I need a clean, up-to-date installation of the open-source ERPNext suite deployed on my existing shared-hosting account. At the moment I’m not even sure whether the host is running cPanel, Plesk, or DirectAdmin, so the first step will be to look at the control-panel details with me and confirm the environment. Once we know the panel you can decide whether the built-in tools are enough or if we should work over SSH to set up the full Frappe bench stack (Python, MariaDB, Redis, Nginx, etc.). For this first phase I am only after the standard ERPNext package—no extra modules, no code tweaks, just the out-of-the-box build running smoothly, secure, and ready for data entry. I will supply the hosting credentials and a sub-domain; you take it from there and hand back a working ...

The job is simple but brisk: slice open cartons of non-perishable goods, lift the contents out, set them neatly on a pallet for identification as some items have been incorrectly labelled.

We’ve organised the floor so the pallets are close by, so you won’t be hauling anything far.

Here is what I need from you: • A step-by-step walkthrough of the signal paths that handle UART traffic between the ESP and the PIC18F, including any level-shifting, buffering, or hand-shake lines that support the link. • A guided tour of the PCB layout that shows where those signals travel—layer changes, vias, ground references, decoupling, and any routing choices that affect integrity or noise. • Simple notes on any supporting circuitry (power rails, oscillators, reset circuits) only as they influence that communication channel.

I’m open to your preferred framework—Electron, WPF, C++, or another—so long as the final deliverable is a single installer or portable .exe. Please inclu...

ONPAGE AND TECHNICAL SEO ONLY FOR 5 pages. My website needs a tight, on-page tune-up that puts proper indexing front and center. I’m focusing first on meta-tag updates—titles, descriptions, canonical tags and structured data—so every page signals clear relevance to Google, Bing and other engines. I already have a seed list of keywords and I want you to grow it only where it can win significant, high-traffic search volume. Please validate my list, map the strongest terms to their most logical pages and adjust the meta tags accordingly. Beyond the tags themselves, I also want technical checks that directly influence crawlability and indexation: XML sitemaps, robots directives, core web vitals warnings, schema implementation and any stray noindex or can...

Basically what I need is: • I have list of words which should be created as a page (sub-page to dictionary) • The list includes link to a site where you have all the text. • Use ChatGpt plus to rewrite the full text (h1, h2, main text etc).

I run a data platform built on Spark and Python, and I need an experienced engineer who can sit with me in Pune three to four times a week (hardly 2 hours in a day) to keep it running smoothly.

I want our website to surface more often—and more prominently—when users ask questions on ChatGPT, Gemini and Bing AI. The primary metric of success for me is a clear uptick in qualified organic traffic that can be traced back to these answer engines. Where I believe we can make the fastest gains is in refining the site’s content quality. Much of our existing copy feels thin or fragmented, so I need an AEO-savvy specialist who can audit current pages, identify gaps, and rewrite or expand material so that large language models select our domain as an authoritative, well-structured source. Solid understanding of entities, schema markup, conversational keyword research and on-page SEO best practices will be essential; however, templates and fluff are not what ...
