From 207,476 reviews, clients rate our Linux Developers 4.9 out of 5 stars.My Juniper EX Series switch has suddenly stopped loading the web interface after I made some configuration changes. The CLI is still reachable, but the browser page never appears, so I can’t use J-Web for day-to-day management anymore. I need an engineer who knows EX Series internals to: • Diagnose why the GUI service will not start or respond. • Roll back or adjust the recent configuration edits—without disrupting live traffic—to restore full J-Web access. • Provide a short note outlining what was fixed so I can avoid the problem next time. Ideally we can screen-share or you can guide me over SSH; I’m ready to supply current config snippets and logs on request. Once the GUI loads normally again and I can log in through a browser, the job is d...
Cisco ASA working through ASDM to tidy up and optimize my current firewall pair. The firewalls are already in active-standby high-availability mode, and we use SSL VPN for remote access.

My custom-built site already has an active Mailgun account waiting to be connected. The goal is simple: every order confirmation and account-related notification must leave the server through Mailgun, reach the customer’s inbox reliably, and appear as though it was sent right from my domain. Here is what I need done: • Domain verification and DNS entries (SPF, DKIM, tracking) completed and confirmed. • API key securely added to the project’s environment file, never hard-coded. • Code hooks inserted so Order Confirmation and Account Notification events trigger Mailgun sends. • Template(s) created or migrated for those two email types, with variables pulling live data. • End-to-end test for each flow, including a bounce/complaint check, to show ...

I am ready to launch a fresh Ubuntu-based VPS that will host the TP-Link Omada Cloud SDN Controller, and I want the environment to be production-ready from day one. Your task is to install the latest Omada software, tune the underlying Ubuntu system, and lock everything down with an intermediate security posture: firewall rules, automated updates, and a proven intrusion-prevention layer (e.g., Fail2Ban or similar). Once the controller is up, I will also need a concise document that shows: • every step you took during installation and hardening, • all credentials or certificates generated, • and a clear, vendor-agnostic backup strategy (where to store the archives, how often to run them, and the exact commands or scripts). Feel free to recommend S3, rsync to anoth...
My local Windows-based Odoo 18 sandbox ran perfectly until a contractor pushed an “ops security hardening” change set. Since then: • Login succeeds only intermittently • The screen often turns blank, key menus disappear, and the session becomes unstable (Blank screen, Missing menus, Unstable session) The culprit likely sits in the custom add-on layer or the recent auth/session code the contractor touched during hardening. I do NOT want a fresh install, random module deletions, or a wholesale rewrite. What I need is a precise repair that restores the original, stable behaviour while preserving the security improvements that actually matter. Scope of work – Inspect the custom add-on, any permission tweaks, configuration edits, or related firewall rules introduc...
cPanel / Exim Email Deliverability Expert Needed – 554 Errors Description: We are looking for an experienced cPanel/Exim email server specialist to troubleshoot an inbound email delivery issue on our company domain.

Deliverables • Installed and licensed (our keys) copies of cPanel/WHM, LiteSpeed, CloudLinux, and WHMCS on AlmaLinux 10 • WH...
I need a fresh SMTP server configured and fully integrated with my existing cPanel account so I can push roughly 1 000–10 000 emails per day through Webmail without bumping into the usual sending limits. There is no current SMTP service in place, so the job starts from scratch: provisioning the server, linking it to my domain inside cPanel, and making sure every authentication layer—SPF, DKIM, DMARC, rDNS—is properly applied for strong inbox placement. Once it is live, I want to be able to open Roundcube (or any default Webmail client that ships with cPanel) and send campaigns confidently, knowing throttling is no longer an issue. Please secure the server, tweak Exim or Postfix for high-volume performance, and leave me with clear, concise notes on how to add future domai...
I have a fully-built MERN stack store—including a React front-end, Node/Express API, MongoDB database and live Stripe integration—sitting in a private Git repo.

I need my Asus RT-BE88U running smoothly with NordVPN so every computer and streaming device in the house automatically tunnels through the VPN and lets us bypass geo-restrictions without killing speed or breaking normal web use. Here’s what I’m after: • Load the correct NordVPN OpenVPN or WireGuard configuration files on the router, including any manual DNS settings needed to stop leaks. • Make sure only the computers and streaming boxes go through the VPN while other gadgets (phones, IoT, printers) can stay on the regular WAN if that keeps things faster. • Verify that Netflix, BBC iPlayer, Hulu and similar region-locked services open as if we’re in the chosen country. • Provide a quick screen-share walk-through so I can tweak or add servers la...
I already have an in-house email-sending tool paired with a verification platform. Before we scale further, I want a fresh set of expert eyes to confirm that everything is configured exactly as it should be and to tighten up any loose ends you spot. Here is what I expect: • A thorough review of the current sending application—server settings, DKIM/SPF/DMARC alignment, bounce and complaint handling, throttling rules, and any other factors that influence inbox placement. • Confirmation that the verification platform is running flawlessly and catching invalid or risky addresses without slowing campaigns down. • Clear, actionable fixes applied immediately where issues are found, plus concise notes explaining what was changed so I can trace the logic later.

I need a genuine, ISP-issued static IPv4 address (Only I use, not shared) that is geographically located inside Pakistan. The line will front-end a small production web server, so uptime, clean routing, and unthrottled ports 80/443 are essential. I’ll also be running my own mail services behind the same address and will therefore require Socks 5 to be open and fully usable. Here’s what I expect from you: • Provision of the static Pakistani IP with clear documentation of the assignment. • Quick walkthrough (or concise guide) showing how to bind the IP to my on-prem machine (Linux) and verify reachability. Once the IP is reachable externally and the basic connectivity tests for the web server, Socks5 succeed, I’ll consider the job complete.
I need an experienced FreePBX professional who will teach me what I want to learn about freepbx operation and backup You can share your freepbx installation or use mine. You will look over my current installation if needed and help me fix the issues so that I can run it smoothly. So the focus is strictly on troubleshooting and ongoing support rather than fresh installation. I plan to use your experience instead of AI support. If you routinely work with Asterisk/FreePBX CLI, have a solid feel for SIP tracing tools such as sngrep or Wireshark, and are comfortable working/teaching on production systems where downtime needs to stay minimal, you are exactly who I’m after. I would like to use a help convenient with my work hours so that I don't cheat with my boss.
I already own the domain; now I need a fully-operational MailWizz environment that I can start using the moment you hand it over. You will supply and configure everything—dedicated Windows server, clean IP address, valid MailWizz license, and any underlying mail transfer agent—so I don’t have to purchase additional components or subscriptions. The build must be optimised for high-volume transactional emails. Rather than relying on third-party relays like Amazon SES, SendGrid, or Mailgun, I’d like to send directly through MailWizz itself, so please install and tune the SMTP/MTA you feel delivers the best inbox placement on a Windows stack. Key deliverables: • Provisioning of a Windows server with a fresh IP • Installation and activation of MailWizz unde...

I’m ready to move past the basics and gain solid, real-world confidence with AWS. The focus is intermediate-level coverage of the three services I touch most—EC2, S3 and Lambda—taught face-to-face rather than online. Here’s what I have in mind: an instructor-led programme that blends concise theory with plenty of hands-on lab time so I can design, deploy and troubleshoot workloads on the spot. Best-practice architecture, security considerations and cost-optimisation techniques for these services should be woven throughout the sessions. We can schedule the training across one to two weeks (I’m flexible on exact days and times). Please let me know where you can deliver the sessions or if you’re able to travel to my location.

I have a small React.js web application ready for production on a private domain. The cPanel account is already live, so I only need help with specific tasks—things like creating the production build, configuring the document root, handling SSL, setting environment variables, and making sure the deployment script runs smoothly each time I push fresh code. Once the site is live, I also need a clean, documented API that external partners can call securely. A lightweight REST endpoint is fine; just be sure it validates requests, returns JSON, and is ready for basic authentication or token headers so it can plug straight into their platform. Please bring solid cPanel experience, comfort with React-friendly build tools (npm, Yarn, Webpack or Vite), and the ability to test the new API fr...
I run several production workloads in AWS here in Singapore and need a partner who can jump in any time—day or night—without the lag a distant time zone creates. Fast, reliable WhatsApp communication is non-negotiable; that is how my team escalates issues and approves changes. Core stack you will care for: • EC2 instances that host our main applications • S3 storage buckets for static assets and backups • RDS databases (primarily MySQL / PostgreSQL) We also lean on Elastic Load Balancing, IAM, and Shield/WAF, so familiarity with those services is important. Beyond break-fix help, I’m looking for proactive value: • Consultation on architecture and cost-/performance best practices • Regular system-health monitoring with early-war...
Two Cisco ASA 5512 appliances • Integrate Microsoft Active Directory authentication for every local and VPN user, • Build an active-standby fail-over pair between the two ASAs • Upgrade the firmware to the current long-term-support release • Add a secondary Internet uplink that rides over a 4G/LTE modem; the ASA should keep the static fibre circuit as primary and fail over automatically to the mobile link only during outages. It is production system so credentials cannot be shared, all work needed to be done on a shared screen. Please bid If you know ASA CLI/ASDM inside out and have handled AD integration and dual-ISP designs
Our network relies on Cisco Identity Services Engine, but recent posture checks are failing and several policy sets are no longer behaving as intended. I need an engineer who lives and breathes Cisco ISE to dive straight into the security-centric side of the platform, isolate the root causes, and rebuild any broken logic so users are authenticated and authorized exactly as our compliance rules demand. The immediate focus is policy development, enforcement, and the associated troubleshooting workflow—no fresh installs, just refining what is already in place and making sure every posture requirement is met without disrupting production traffic. You will have full access to the existing ISE nodes, logs, and current policy matrix, plus remote console time with our network team for c...
My brand-new AlmaLinux 10 server is still empty and I already have full root access, so I’m looking for an experienced systems engineer who can turn it into a production-ready hosting platform in one sitting. Here is what I need done: • Install and license cPanel/WHM, then apply the recommended security hardening. • Replace Apache with LiteSpeed (Enterprise) and ensure the global and per-account settings are tuned for performance. • Enable CloudLinux with CageFS, LVE limits and PHP Selector so future user accounts are fully isolated. • Add Softaculous and verify that one-click installs work out of the box. • Create at least one WHM reseller package that I can clone for future resellers. • Verify that all services (DNS, Exim, Dovecot, FTP, Aut...
I’m looking for someone who can take me from a blank or malfunctioning drive to a fully-functional operating system, ready for everyday use. The task is strictly technical support focused on the installation itself—I’ll supply the license key or image, you guide or carry out the setup. Here’s what I expect: • Selection and verification of the correct OS image • Clean or upgrade installation, including basic partitioning if required • Activation, first-time updates, and driver checks to be sure the machine boots and runs smoothly If any minor post-install hiccups appear, I’d like quick pointers to resolve them, but we’re not stepping into full troubleshooting or long-term system maintenance for this project. Let me know your preferre...
I run a service center and I’m ready to streamline two key touch-points at once: inbound customer support calls and WhatsApp messaging. I am not working on CRM and ticketing system, so the solution must plug directly into both of those platforms—ideally through secure APIs or webhooks—so every interaction is logged automatically without any manual data entry. I only need straightforward rule-based flows: IVR menus for phone calls, and button- or keyword-driven replies on WhatsApp. Natural-language understanding is not required; speed, reliability, and clear routing rules are the priorities. Please propose the tech stack you’ll use (Twilio, 360dialog, Asterisk, Vonage, Dialogflow CX in “no-NLP” mode, or any other you prefer) along with the integrati...

I need a Coordinated Vulnerability Disclosure system built entirely from open-source components and delivered as software only—no appliances or proprietary add-ons. The core feature I must have is a robust workflow for tracking and managing reported vulnerabilities, from initial submission through resolution and disclosure. The application has to run smoothly on a Linux server, so please choose libraries and frameworks that are well supported in that environment. For user access, multi-factor authentication is mandatory; I want researchers, internal engineers, and any third-party responders to sign in with something stronger than a simple password. You are free to select or combine existing open-source projects (for example, Bug Bounty platforms, ticketing systems, or secure mess...

Please document each command you run so I can repeat the procedure in future emergencies. Deliverables • Root login via SSH or console confirmed working • Step-by-step notes (command history and short explanations) • No data loss or service disruption during the process ...
I need a reliable way to pull full-length movies and TV episodes from popular streaming platforms that sit behind Cloudflare, trigger Turnstile / reCAPTCHA, and deliver their streams through Widevine-protected playlists. The goal is a single tool—CLI or small library—that can: • Negotiate every Cloudflare layer automatically (token / challenge handling, TLS fingerprinting, rotating proxies if required). • Detect and solve any captcha that appears, handing the solution off to a third-party service key I will provide. • Acquire the playable video once the page is reached and either expose the raw HLS/DASH URLs or decrypt the Widevine L3 stream on the fly so the final output is a clear MP4 or TS file.

Admin Dashboard (Single User): Secure login for me (the admin) only. Client Management: Add, modify, or delete clients. Sensor Management: Assign temperature/humidity sensors to each client. Contact Management: Store client phone numbers and emails for alerts and monthly reports. 2. Alert System: Configure alarm thresholds (min/max temperature, min/max humidity)...
I have a set of raw FASTQ files from a personal research project and I want to take them all the way through to biological insight. My primary goal is to identify differentially expressed genes, and I already have both the reference genome and its matching GTF/GFF annotation ready for you. Here is the pipeline I want to see implemented: • Initial quality check with FastQC followed by an aggregated MultiQC summary. • Adapter and low-quality base trimming. • Alignment to the reference (or transcript-level quantification if you prefer Salmon/kallisto) under a well-documented, reproducible Linux environment. • Gene-level count matrix generation, then differential expression with DESeq2 in R. • Exploratory visualisations: PCA, heatmap, and a volcano plot highl...
I run all of our transactional and marketing messages through a custom-built SMTP server, and I now need every single message we send to show a new “from” address. That address has not yet been added or verified on the server, so the first step will be setting it up properly, completing whatever SPF, DKIM, and verification steps are required, then updating the server configuration to make it the default sender. Once the address is live and trusted, I want the change enforced globally—no edge cases where an older identity slips through. After you update the SMTP settings, I’ll need a quick proof: send a few sample messages my way and show the headers so I can see the new address, correct DKIM signature, and a pass on SPF. If you have experience with Postfix, Exim, ...
