What I'm looking for

I seek backend roles focused on high-scale .NET systems, performance optimization, and building resilient data pipelines in teams valuing clean architecture and measurable business impact.

I am a Senior Backend Engineer focused on building high-scale, data-intensive systems in the .NET ecosystem, with deep experience in SQL Server and PostgreSQL. I have a proven track record of transforming legacy distribution systems into high-performance engines, delivering dramatic latency reductions and substantial operational throughput gains.

I design resilient ETL pipelines, automation engines, and high-concurrency processing solutions that produce measurable business results — from 90% query time reductions to multi-million-dollar profit improvements. I follow DDD, Clean Architecture, and SOLID principles to create maintainable systems prepared for microservices evolution.
