    I have several full-stack products in production—an online course manager, a housekeeping management tool, an HR portal, and an online bookstore—and I’m now focusing on squeezing every millisecond out of their Django back-ends. Your task is to step into one of these projects (the choice will depend on your past experience and interest) and raise its performance ceiling. Database queries, caching layers, asynchronous tasks, and deployment tweaks are all fair game as long as they translate into faster response times under load. What I’ll share once we start: • Source code and current deployment setup (Docker + PostgreSQL + Redis) • Baseline benchmarks and target response-time goals • A short list of user flows that must remain unchanged functio...

    I need a clean, conversion-oriented landing page that presents my PHP script as a premium digital product and drives visitors straight to purchase. The copy and layout should highlight the script’s key features in an eye-catching section and funnel users toward a prominent call-to-action button that links to my existing checkout flow. Design notes • Modern, responsive layout that feels trustworthy on desktop and mobile • Visual emphasis on the feature block—icons or concise graphics are welcome • Single, unmistakable CTA button (“Buy Now” / “Get the Script”) fixed or repeated near the fold • Smooth scroll, lightweight animations, and fast load speed (HTML5, CSS3, JavaScript) • Easy for me to update text or add future t...

    My site works fine on desktop, but on phones and tablets the interactive parts fall flat. Forms and other input fields can be tapped all day without a cursor ever appearing, and key buttons or links refuse to react—no clicks registered, no navigation, nothing. It isn’t a speed or layout problem; the issue is pure interactivity. I need someone to dive into the mobile styles and scripts, spot whatever is blocking touch events, then patch it so every form element and call-to-action responds smoothly on current iOS Safari and Android Chrome. A quick audit of any JavaScript libraries, event listeners, and CSS overlays that might hijack taps will probably be required, and I’m happy to supply repo access and staging credentials straight away. Acceptance criteria • All...

    We’re ready to bring an experienced QA engineer into our remote product squad so every build leaves our pipeline bullet-proof. Your first job will be to craft and run thorough functional test plans for our iOS and Android apps, partnering daily with backend and mobile devs through Slack and the CI dashboard. The immediate focus is to walk every user-facing flow end-to-end—authentication, payments and real-time sync—on real devices and emulators. You’ll log defects in Jira with crystal-clear reproduction steps, confirm fixes on the next build and keep a tight feedback loop going until the issue count hits zero. Regression and integration coverage for our REST APIs will follow once the core mobile work is stable. If you’re comfortable layering in automated tes...

    I am fine-tuning an AI system that uses retrieval-augmented generation to turn uploaded source documents into polished SDD (Software Design Description) sections. The current YAML prompt set is drifting: I see hallucination in the output—mostly content that the model half-understands or slightly twists rather than outright fabricates—and that small inaccuracy snowballs into wrong field mappings and cluttered tables. Your main mission is to open the existing prompt files, compare them line-by-line with the business template, and tighten the instructions so the model only returns evidence-based facts. Template alignment is the area that clearly needs the most love, yet the retrieval and synthesis rules also deserve a second look to be sure we are not hard-coding project-specif...

    Bug fix in a real-time chat application. Context: chat messages are stored as generic ChatEvent rows in Postgres, with no dedicated flag distinguishing a private message from a public one — private messages currently arrive with a text-based marker prefixed to the message body (e.g. a bracketed tag at the start of the string). The frontend chat component already has a fully built, distinct rendering path for private messages (different visual treatment) — it just never gets used, because the API route that serves chat events to the frontend maps every single row to the generic "chat" type regardless of content, so the private-message type the frontend already knows how to render is never actually emitted. Task: update the API route so it correctly detects the priv...

    I’m looking to build a clean, timeless website that simply tells visitors who we are and what we do. The project is strictly informational—no carts, check-outs, or complicated back-end logic—yet I still want it to feel premium. My visual preference leans toward modern, minimalist layouts: generous white space, crisp typography, subtle motion, and a colour palette that lets the content breathe. Content scope The heart of the site is a single, well-structured Services page. I’ll provide the copy, basic brand colours, and any supporting images or icons; your job is to turn that material into an elegant user experience that loads quickly on mobile and desktop. Tools & build approach I’m open to WordPress, Webflow, or a lightweight custom build in HTML/CS...

    I’m looking to turn our commercial-excellence vision into a working MVP that every member of the sales organization can open, understand, and act on. The core of the job is a web-based dashboard that plugs directly into our CRM, ERP, and Datalake, consolidating those feeds into one clear view. What the dashboard must do • Display real-time performance metrics so managers and reps immediately see where they stand against target. • Generate an automatically refreshed list of priority actions for each user, guiding day-to-day execution. • Show concise integration status indicators so everyone can trust the underlying data at a glance. User scope Both managers and sales representatives will use the same interface, so role-based filtering or permission logic will be nee...
