01 / About

I'm a Senior Full-Stack Engineer with 5+ years of experience designing, developing, and delivering scalable web and mobile applications across international teams.

Expert in modern JavaScript frameworks — React, Angular, Next.js — backed by powerful server-side stacks including Node.js, NestJS, Django, and Python. I deploy on cloud infrastructure with AWS and Docker, and have shipped AI-driven features, microservices, and automation pipelines.

Beyond engineering, I lead. I've grown and managed teams of 8+ developers, introduced Agile practices that measurably improved delivery speed, and mentored engineers at every stage of their careers.

Outside of code: bodybuilding teaches discipline and consistency. Philosophy sharpens how I approach problems. Gaming keeps my strategic mindset sharp.
