Full-Stack Developer

Leonid
Nazarov

I build web apps end to end — the frontend, the backend, the database, and the Linux server they run on.

About

Full-stack developer working with JavaScript / Node.js and Python. I cover the complete development cycle: frontend, backend, SQL and MongoDB databases, and deployment on Linux servers I configure myself.

Beyond web development, I have hands-on experience with networking (Cisco Packet Tracer, Wireshark), Linux server administration, and embedded systems (ESP32 / Arduino). I learn fast — every technology in my stack turned into a working project within months.
