What I'm looking for

I’m looking to lead backend/platform initiatives—event-driven services, CI/CD standardization, and observability—while partnering with US-based stakeholders to ship reliable production systems on AWS and modern .NET/Node stacks.

I’m a backend and full-stack engineer with 7+ years shipping production systems on .NET/C# and AWS, with hands-on depth in Node.js, TypeScript, and PostgreSQL. I design REST APIs, integrate third-party ERPs and SaaS platforms, and own cloud infrastructure end-to-end—comfortable partnering with US-based stakeholders in English.

I’ve led platform-level initiatives like event-driven messaging, CI/CD standardization, and observability (OpenTelemetry, Grafana, Loki) used by ~20 engineers across 20+ production sites. I also delivered high-impact ERP work—building SAP Business One add-ons and internal tooling that reduced deployment time by ~4 hours per project—while continuously modernizing systems through migrations and performance-focused engineering.
