About

I’m a Senior Software Engineer with 10+ years of experience building scalable backend platforms, distributed systems, and cloud-native applications. I specialize in designing reliable microservices and integration patterns using Python and Java, and I’ve modernized legacy systems into platforms that are easier to maintain and faster to evolve.

I also bring strong hands-on experience with AWS serverless architectures, multi-tenant SaaS, and production reliability practices like observability, performance tuning, and failure isolation. In recent work, I’ve integrated LLM-powered capabilities into enterprise workflows and built end-to-end orchestration and data transformation pipelines that help teams automate complex processes securely and efficiently.
