What I'm looking for

I’m looking to build and modernize distributed backend systems for SaaS, with strong engineering standards, test coverage, and reliability-first practices. I want hands-on ownership, great CI/CD and observability, and room to apply AI to debugging and search.

I’m a Senior Software Engineer with 15+ years building production B2B and SaaS platforms. I focus on distributed services, clean architecture, and reliability practices—delivering and modernizing systems using C#/.NET, Go, and Node.js/NestJS, with strong experience in API design (REST, gRPC) and safe change practices.

I lead backend and platform efforts hands-on: CI/CD, containerized environments (Docker, Kubernetes, GCP GKE, AWS), and observability (OpenTelemetry, Jaeger, Grafana, Kibana) to speed up debugging and production monitoring. I also actively use AI-assisted dev workflows (Claude, Cursor, Copilot) and explore AI-driven features like embeddings, semantic search, and LLM assistants in my projects.
