ABOUT

cat about.txt

I'm a senior backend developer with more than ten years of building and maintaining high-load web applications, distributed systems and scalable backends. My core is the PHP/Symfony ecosystem: asynchronous processing, relational databases, infrastructure tooling and backend optimization.

I've modernized legacy systems, worked with microservices and orchestration services, and run production environments with large volumes of data. I care about maintainable architecture, performance and pragmatic engineering — and I actively use modern development and automation tools to ship faster.
