I'm a Senior Software Engineer & Software Architect with 20+ years of experience building backend systems, distributed architectures, and cloud‑native solutions. My core background is .NET / C#, with strong hands‑on experience in Java + Spring, event‑driven architectures, and DevOps / CI‑CD.
I enjoy working on complex systems, critical integrations, and platforms that demand scalability, resilience, and clean architecture. I'm naturally curious, pragmatic, and strongly driven by engineering best practices.
