What I'm looking for

I'm seeking a role building scalable, high-performance applications with microservices and RESTful APIs, in collaborative teams that value clean architecture and measurable performance gains.

I'm a results-driven Full-Stack Developer with 3 years of experience building backend and frontend systems using PHP (Laravel), Python (Django, FastAPI), and JavaScript (React, Vue.js).

I have a proven track record of optimizing performance — reducing API response times by 15% and page load times by 25% — and implemented server-side caching and microservices-based architectures.

I designed and developed over 20 RESTful endpoints for high-load analytics platforms, executed a seamless migration of legacy modules with 100% service availability, and integrated 5+ third-party APIs including a Telegram bot.

I hold practical training in software development and a Bachelor’s in Integration of Smart Technologies; I've won multiple hackathon prizes and now seek to build scalable, high-performance applications in collaborative teams.
