What I'm looking for

I’m looking for a remote or relocation-friendly team where I can build secure full-stack MERN/Next.js apps, ship real-time WebRTC + Socket.IO features, and deploy microservices with Docker and serverless tools—while collaborating closely with clients.

Full-Stack JavaScript Developer specializing in MERN, TypeScript, and Next.js, with hands-on experience deploying containerized microservices (Docker) and real-time systems (WebRTC, Socket.IO).

I bring 3 years of client relationship management experience to every project, which means I don't just write code — I understand business goals and communicate clearly with stakeholders throughout the development lifecycle.

Recent work:

Built Quick Poll, a real-time voting app with Next.js 16, Express, Socket.IO, and Redis on Railway

Developed Healthy-Connect, a telehealth platform with WebRTC video consultations, JWT security, and CI/CD pipelines on Vercel/Render

Reduced API latency by 40% through strategic database indexing

Tech stack: React 19, Next.js, Node.js, Express, PostgreSQL, MongoDB, Redis, Prisma, Docker

Available immediately for remote full-time or contract roles. Open to European time zones.
