About

Jelena, Full-Stack Developer

I'm a full-stack developer based in France, working mainly with the MERN stack. I started with a front-end development program at Studi in February 2025 and graduated in April 2026. I then moved to the back end because I wanted to build complete products, not just interfaces.

Today I build React front ends, Node.js and Express APIs, and MongoDB databases, and I enjoy connecting all three into something that really works. My projects, including a restaurant app and a hotel booking app, are on GitHub, and most of them are deployed online.

I'm currently open to full-time positions and freelance projects. I enjoy collaborating with a team, I can also work independently, and I'm always eager to learn new tools.

Frontend Development

Responsive, accessible interfaces built with React, TypeScript and Tailwind CSS, from reusable components to smooth interactions.

Backend & REST APIs

Server-side applications and REST APIs with Node.js and Express, connected to MongoDB databases.

Full-Stack Applications

End-to-end web apps on the MERN stack: from database and API to the interface users interact with.

Design to Code

I turn Figma designs into pixel-accurate, responsive interfaces that work on desktop, tablet and mobile.
