As a Backend and DevOps ∞ engineer, I specialize in designing services that behave consistently — whether they’re running in a staging cluster on a quiet Tuesday afternoon or handling production traffic during a peak load spike. For me, resilience, observability, and predictability aren’t afterthoughts — they’re built in from day one.

My experience spans distributed systems, cloud-native infrastructure, and production-ready microservices. I’ve scaled high-throughput systems, managed workloads across Kubernetes clusters, and integrated LLMs into real-world apps using AI Agentic and Retrieval-Augmented Generation (RAG) techniques.
My goal? To build systems that make future developers nod in appreciation and think: “Yep, they knew what they were doing.” 🚀
