What I'm looking for

I seek senior backend roles where I can drive scalable, high-performance systems, mentor teams, work with cloud and distributed architectures, and solve complex production challenges in a collaborative culture.

I am a Senior Software Engineer with 9+ years of experience building and optimizing backend systems using Java and microservices. I specialize in debugging, performance optimization, scaling systems to handle millions of telemetry events, and integrating distributed components including blockchain and crypto wallet integrations.

I have led work across legacy-extension, over-the-air firmware updates, microservices performance improvements, P2P messaging and private blockchain networks using Hyperledger Fabric, and data curation pipelines. I prioritize reliable production support, RCA-driven fixes, and pragmatic engineering that bridges product and infrastructure needs.
