Ubuntu Jobs

We are seeking a highly skilled developer with expertise in Aeron and SBE to engineer a greenfield, ultra-low latency cryptocurrency market-making core on AWS. The goal is to achieve an internal tick-to-trade latency of <50 microseconds (p99) on the "Hot Path." Key Objectives: - Implement a single-server, multi-process architecture where Data Ingestion, Strategy, and Execution communicate via Shared Memory (IPC), bypassing the network stack entirely for internal messages. - Leverage Aeron (for transport) and SBE (Simple Binary Encoding) to eliminate garbage collection and object copying. - Ensure the system runs efficiently on AWS c5n instances with Kernel Bypass and CPU Pinning enabled. Deliverables: The project will be divided into three milestones: 1. Miles...

I have an extremely powerful Framework Desktop with 128GB of RAM, 2 storage drives (8TB SSD, and 4TB SSD), 1 gbps+ networking, and an AMD Ryzen AI Max 385 CPU (16 core 32 thread), currently running TrueNas. I’d like to set it up as my own private server, so I can run Jellyfin (and fill the libraries), have an easily accessible Windows VM from anywhere (doesn’t need to be great), a Minecraft server (silly, I know, but setting it up as a college community leader so that housing can play together), and open-webui (or more later). I already have the datasets organized and the “apps” installed in their respective Docker containers (I think). Routed through cloudflare, certain domains are set-up for remote access to every part of the system as well, but I am relatively...

Please install and configure a fully-functional 7 Days to Die multiplayer server on my existing Linux VM. I want the latest stable game build, no mods or custom plug-ins—just a clean, reliable vanilla experience. Key points you should handle: • Install the current stable dedicated-server files. • Configure ports, firewall rules, and any required dependencies so players can join externally without issues. • Create a simple, documented configuration () with sensible defaults I can tweak later—world seed, player slots, basic permissions, and scheduled backups. • Set the service to start automatically on reboot (systemd or your preferred method). • Provide step-by-step notes of everything you touch so I can maintain or replicate the setup if need...

I'm looking for a Docker Compose setup that includes OpenResty, Certbot, and a reverse proxy. Additionally, I need Lua scripting for request/response manipulation. Requirements: - Docker Compose file - OpenResty as web server - Certbot for managing single domain SSL certificates - Reverse proxy configuration - Lua scripts for request/response manipulation Ideal skills and experience: - Proficiency in Docker and Docker Compose - Strong knowledge of OpenResty and Nginx - Experience with Certbot and SSL certificate management - Lua scripting expertise - Familiarity with reverse proxy setups

I need an Ubuntu-based distribution that behaves much like a Kasm workspace image but ships with my own presets baked in. The final result should be delivered both as an ISO (for bare-metal or VM installs) and as a ready-to-run Docker image so I can spin up identical workspaces on demand. Core requirements • Base: latest LTS Ubuntu • Desktop: GNOME, trimmed to essentials so the image stays lean • Security: hardened defaults, pre-configured firewall, minimal services, confined apps where practical (AppArmor or similar) • Network: static and DHCP profiles ready, predefined DNS, proxy support, and a scriptable way to toggle them • UI tweaks: custom theme, branded wallpaper, default apps removed/added per my list (I’ll supply it once we start) Acceptance criter...

I need CentOS 8.2 (2004, minimal) installed on our KVM-based server using the official ISO I’ve placed here: The key requirement is that the machine must stay on 8.2; the automatic leap to 8.5 has broken our vendor-supplied software twice already. Please handle the install in a way that prevents any post-install upgrade (e.g. disabling problematic repos or locking the release stream). I’m specifically looking for someone who has done legacy CentOS or RHEL builds under KVM before and can demonstrate it. Non-KVM generalists really won’t be the right fit. Deliverables • A fully bootable CentOS 8.2 minimal system accessible over SSH • Written notes on the steps taken to lock the version, so we can reproduce the process later if needed Let me know your tur...

I’m looking for someone who can physically come to our New Delhi office—remote work is not an option—to take charge of an urgent Mobodoa mail server assignment running on Ubuntu. The machine is already live on the old Mobodoa build, but I need a specialist who can refine the initial server setup, complete the configuration, and handle a full upgrade-and-migration cycle to new hardware without disrupting mail flow. You’ll be expected to arrive on-site, review the existing Ubuntu environment, adjust any misconfigurations, migrate data and user accounts cleanly, then validate that everything functions exactly as before—or better—once the cut-over is done. Solid knowledge of Ubuntu server administration, Postfix/Dovecot, DNS, SSL/TLS and mail security best ...

Job Description: We are looking for an experienced AWS Terraform DevOps Engineer to join our team for a long-term project. Candidate must have a minimum of 3 years of commercial experience and strong expertise in the technologies listed below.

I need an experienced AWS engineer to spin up and fully configure a new EC2 instance ready for production use. The work goes beyond a vanilla launch—I want the machine hardened and aligned with basic compliance requirements from day one. Core tasks • Configure the EC2 instance with the chosen AMI, correct instance size and network settings. • Implement firewall rules through Security Groups and, if useful, NACLs so only the intended ports are exposed. • Enable data encryption at rest and in transit—this includes encrypted EBS volumes and SSL/TLS for any services you help me install. • Activate compliance auditing with tooling such as CloudTrail and AWS Config, making sure logs are stored safely and immutably. I will provide the AWS account, VPC details and...

I need a clean, command-line–only installation of Ubuntu on a fresh machine. No desktop environment, just the core OS so I can build out services later. Here’s what I expect from you: • Perform (or walk me through) the installation, handling disk partitioning and boot settings as required. • Apply the latest updates and confirm the system boots straight into the CLI. • Enable secure, password-protected SSH so I can reach the server remotely. • Send me a brief summary of the steps taken and any credentials you created. If you prefer to guide me rather than take direct control, that’s fine—just let me know which remote tool you’d like to use and how long the job will take.

I already have a CloudFormation template that launches EC2 instances and an ECS cluster to run a Python-based Docker container. The stack works, but several resources now need tweaks and clean-up rather than wholesale replacement. Once we connect, I’ll share the current template, the running stack’s state, and the change log I’ve collected so you can dive straight in. Scope of work • Update or refactor existing EC2 and ECS resources so the service starts cleanly with every deployment. • Tidy up IAM roles, security groups, and any hard-coded parameters that could be moved to the parameter section. • Align task definitions with the latest Docker image (Python 3.11) and confirm logging/monitoring still flows to CloudWatch. • Validate the modified...

I’m looking for a patient, hands-on mentor who can accelerate my journey toward production-ready mastery of Kubernetes. Containerization with Docker is the next priority, and I also need guidance on managing endpoints across both Linux and Mac fleets, plus a primer on tying everything together with solid API management practices. Here’s what I need from you: • A structured learning path that starts with core Kubernetes concepts—deployment objects, networking, Helm, RBAC—and quickly moves into day-to-day cluster operations and troubleshooting. • Practical Docker containerization exercises: writing efficient Dockerfiles, multi-stage builds, image hardening, and pushing to registries. • Best-practice workflows for endpoint management tools that su...

I am building a claim-style userbot that must beat roughly forty competing bots in the same Telegram channel. Using Telethon with raw MTProto, I need a solution that: • Opens and maintains a single Telegram client session on Linux. • Listens to channel traffic in real time and reacts to every new message the moment it arrives—in practice, I’m aiming for sub-second latency measured from server receipt to callback press. • Immediately clicks the first available inline callback button associated with that message. • Provides a simple way for me to adjust the target channel, keyword filters (if any) and the exact callback index without digging through code. I will consider the project complete when the script consistently triggers before the majority o...

Each time I push my project from GitHub to DigitalOcean and hit redeploy, all of my PostgreSQL records vanish. The application itself comes back up but the database is completely empty, so I clearly haven’t configured persistence correctly. Here’s what you’ll walk me through in a live video call (no hands-on coding from your side, just guidance and screen-sharing while I do the typing): • Identify exactly how my Postgres instance is running in DigitalOcean (managed database, Docker container, or one-off service) and confirm whether a volume or external DB is needed. • Show me the correct way to attach or mount persistent storage so data survives every redeploy. • Help me migrate the current credentials out of the GitHub repository and into proper en...

The goal is to set up an on-premise server that will act as our central hub for file storage and sharing. Fewer than ten employees will access it daily and the data will mainly be documents and spreadsheets, so speed, reliability, and straightforward permission control matter more than heavy multimedia performance. Here is what I need done: • Specify suitable hardware or a cloud-ready small form factor that fits a typical office environment. • Install and configure the operating system of your choice (Windows Server, Ubuntu with Samba, or another stable platform) and keep it fully patched. • Create shared folders, user accounts, and permission groups so each team member has the correct read or write access. • Enable simple remote access for staff working from ho...

I am forking the open-source Outline VPN code-base and need it rebuilt under my own brand. The priority is a rock-solid Windows desktop release first, with the architecture kept clean so we can move on to Linux, iOS and Android later. Here is what I already have and what I need from you: • Brand assets: a complete colour palette and an app icon are ready to drop in. • Open-source starting point: Outline’s client and manager repositories will be the foundation. • Subscription model: the finished client must talk to a simple licence server or Stripe-backed API so users can create, renew and cancel paid plans. • Global server pool: please provision—or show me how to provision—secure VPS nodes in multiple regions, wire them into Outline’s...

I want to run a full-featured XIBO signage server inside the container environment that Mikrotik RouterOS v7 offers. In other words, the end goal is a self-contained “Mikrotik Docker container with XIBO signage” that boots with the router, serves the CMS over the LAN (and, if I open ports later, the WAN), and survives firmware upgrades and power cycles. The container must be based on a Linux image, use persistent storage for the database and the CMS library, and expose the usual Xibo ports so that players can connect without extra NAT tricks. I also need a concise set of commands or a script I can paste into the Mikrotik terminal that: • pulls the correct Linux image • copies the XIBO files and creates volumes • maps ports and assigns an IP / bridge &bull...

**No AI or Automated Bids Please** I am looking for someone to help redploy a Kubernetes cluster we have setup for high availability in a few days. The previous one was compromised so you will need to follow a small documentation to redeploy it the same way. Odoo is hosted on high availability K8 pods within Proxmox VMs using Longhorn for storage. Only parts that need to be setup includes redeploying the control plane with kube-vip, reinstalling Longhorn with properly sized storage, rebuilding the CloudNativePG PostgreSQL cluster with correct replication and backup settings, and reconfiguring ingress/load balancing. It will require a strong background with experience with the following technologies in the order of importance and excellent communication in English: - Kubernetes - Docke...

I run an Ubuntu VPS on IONOS and already have three cron jobs that drive a Chrome browser through Selenium. Right now the box is missing a properly configured Selenium server, so the jobs are failing. Here’s what I need from you: • Install Chrome (or Chromium) together with a matching Selenium Server/Driver. My version preferences are flexible—as long as the pairing is stable and well-supported, I’m happy. • Register Selenium as a systemd service (or equivalent) so it starts automatically after a reboot. • Verify that each of my three existing cron jobs launches, runs, and exits without errors. • Hand over a brief text file with the basic installation and restart steps, nothing elaborate—just enough for me to repeat the process if I eve...
