I build systems that stay steady — the kind that don’t panic when traffic surges or when no one’s around to babysit them.
Most of what I build runs quietly in the background: distributed services, event-driven pipelines, and cloud infrastructure that keep things running without fuss. I like making complex systems feel simple — predictable under load, graceful under failure, and boring in the best possible way.

My work spans Backend, DevOps, and AI-systems — designing scalable microservices, automating deployments, and wiring up LLM and RAG components that actually earn their keep. My toolkit includes Go, Java, and Python, alongside Spring Boot, Kafka, Kubernetes, Postgres, and AWS/Azure.

I’m not here to chase hype or reinvent what already works. I’m here to build foundations — code that holds up under pressure, infrastructure that explains itself, and systems that make future engineers nod and say, “Yeah, this was built right.” 🚀
