About
Building systems that hold up under pressure
I am a full-stack developer with solid experience in backend systems, scalable architecture, and data optimization. I started my academic journey in Archaeology, but I have always been drawn to software and technology since high school — and in my fourth year I left university to fully focus on my software career.
Since then, I have worked with companies like Kentkart, Bisu, and Gomeed, led development teams, contributed to open-source projects, and built production-level systems using Node.js, MongoDB, Redis, and PostgreSQL. I keep growing through hands-on experience and lifelong learning.
In my current work I actively use AI coding tools such as Claude CLI, Antigravity, and Codex to go beyond standard workflows and meaningfully improve development speed, code quality, and overall productivity.
I'm a backend-first full-stack developer. I can ship a working frontend end to end — especially with today's AI tooling — but UI and UX aren't my craft. Where I deliver real value is the backend: making systems fast, reliable, and built to scale.
