JS Ekspres Jobs

I want to launch a lean but fully working social network that feels familiar to Instagram users and is built entirely with React on the front-end, Node.js on the back-end and PostgreSQL as the data store. Core features I need from day one are: photo and video sharing (upload, display, feed), real-time direct messaging between users, and rich user profiles with avatar, bio and basic follow / unfollow mechanics. For authentication I only need a solid email-and-password flow right now, but the codebase should be organised so that OAuth providers can be slotted in later without a full rewrite. Please structure the project as a modern SPA: React (hooks, context or Redux if you prefer), responsive UI, lazy-loaded media, and clean routing. The server may use Express or a comparable Node fra...

I’m ready to turn a new idea into a fully functioning web application and need an experienced full-stack developer to make it happen from the ground up. The scope covers everything: planning the architecture, designing a clean front end, wiring it to a secure and efficient back end, and deploying the finished product to a production-ready environment. Front end I’m flexible on the framework—React, Angular or Vue.js can all work—so feel free to recommend the stack you’re most productive with, provided it delivers a fast, responsive user experience across modern browsers. Back end & data layer You’ll own the server-side logic, API design, integration with third-party services, and database modelling. I’m open to the language and database yo...

I’m building a desktop-first web application and need a full-stack developer who can own the project end to end. The core features I want online in the first release are real-time notifications (think WebSocket or Server-Sent Events speed) and a solid data-analytics layer that lets me surface key metrics in clear dashboards. Right now I’m targeting desktop browsers exclusively; mobile and tablet support may follow later, so clean, modular code that can be extended is important. I’m flexible on the exact tech stack, but I’m already familiar with React, Node.js, PostgreSQL and would prefer to stay in that ecosystem if it speeds us up. If you have a better suggestion I’m open to hearing it, as long as we don’t compromise on performance or maintainability...
