Evgenii G.

Full-Stack Developer specializing in JavaScript, TypeScript, React, Next.js and Node.js. I work with businesses and product teams as a B2B contractor, helping build, extend and maintain production web applications. I can take ownership of a feature or an entire frontend, work with an existing codebase, build new functionality, integrate APIs and third-party services, and handle the technical work needed to get it into production. My main stack: • JavaScript / TypeScript • React / Next.js • Node.js • PostgreSQL • REST APIs / WebSockets • Tailwind CSS / shadcn/ui • Material UI / Bootstrap • Docker / Nginx • AWS infrastructure and deployment I have hands-on experience with both frontend and backend-related tasks, including server setup, deployments, Nginx configuration, AWS services and storage buckets. I’m comfortable working across the application rather than being limited to just one part of the stack. Some of the products I’ve worked on include: • A production dApp frontend built from scratch as the sole frontend developer • A scalable AI chat widget distributed as NPM modules, with multi-tenant architecture, WebSockets, audio chat, Markdown and tenant-specific configuration • A document automation platform for a Spanish company, including dynamic PDF generation and data-driven graphical documents I focus on practical, maintainable solutions and getting features shipped to production. If you need an external developer to build a feature, improve an existing application or provide ongoing development capacity, send me the details and I’ll be happy to discuss the best approach.
