    I have a queue of ongoing web applications that need extra hands right away. Everything is full-stack: html template for front end Laravel powers the back end, so you should feel equally comfortable jumping between components, blades, controllers, and API endpoints. During the first phase you will connect to my development machine through AnyDesk or TeamViewer. From there you’ll reach the private servers and scripts you’ll be updating. Each task arrives in a concise ticket that includes screenshots, a short problem statement, and acceptance notes; I’ll be online to clarify anything in real time. Up to five tickets can be open at the same time. As you add or refactor code, please: • keep formatting consistent with the existing style guide, • write brief doc-...

    My Ruby (Rails) API usually answers in milliseconds, yet at unpredictable moments the same endpoints take seconds to return. Standard logs show no spikes in traffic, and CPU / memory look normal, so I suspect a hidden bottleneck—perhaps DB connection exhaustion, an elusive N+1 query, or a background job starving Puma threads. You will dive into the codebase, profile the request/response cycle, pinpoint the root cause, and supply a clean fix that restores consistent response times. Feel free to use rack-mini-profiler, New Relic, Scout, or your preferred Ruby profilers; the server runs Ruby 3.1 and Rails 7 on PostgreSQL. Deliverables • Diagnostic report summarising findings and root cause • Patch or pull request with the optimised code/configuration • Before-an...

    I’m ready to launch a full-featured social networking web application and need a developer who can take it from concept to production. The core experience revolves around three must-have features: rich user profiles, a real-time messaging system, and an engaging activity feed that keeps everyone up to date on posts, likes, and comments. The site has to be entirely browser-based, mobile-responsive, and built with clean, well-documented code. I’m open to the modern stack you prefer—whether that’s React or Vue on the front end, a Node/Express, Django, or Laravel backend, and a solid relational or NoSQL database—so long as it scales, is secure, and performs smoothly under load. Deliverables I expect: • Wireframes or a clickable prototype to confirm UX...
