What I'm looking for

I'm looking for opportunities to architect and modernize high-load web systems, lead full-stack development, improve legacy codebases, and build reliable Laravel, React, DevOps, and Linux infrastructure.

I architect high-load web systems at Renisance art group, including the Studylancer platform built from scratch with Laravel, React, TypeScript, SOLID principles, CI/CD, and Linux server orchestration supporting 99.9% uptime.

Across Infoflot and Neoline, I've built responsive interfaces, integrated REST APIs, improved loading speeds by 30%, optimized SQL databases, and refactored legacy PHP and jQuery modules into reusable, maintainable components. I also design distributed systems with SSO, JWT access control, transactional wallet flows, real-time classrooms, and secure media management.
