What I'm looking for

I seek a technical leadership role where I can design scalable, secure systems, mentor engineers, and drive cross-team reliability and performance improvements.

I am a Principal Development Engineer with 8 years building distributed, fault-tolerant infrastructure and high-performance APIs across industries including e-commerce, finance, insurance, retail, and healthcare.

I design and implement scalable microservices, API gateways, and telemetry pipelines using Java, C#, Python, TypeScript, cloud-native tooling, and observability stacks to improve reliability and latency.

I have led cross-team migrations from monoliths to microservices, reduced deployment time and MTTR, mentored engineers, and standardized observability and federation practices adopted org-wide.

I prioritize secure, testable, and maintainable systems, driving architectural decisions, implementing CI/CD and SRE practices, and delivering measurable improvements in throughput, latency, and operational visibility.
