What I'm looking for

I seek backend/platform roles where I can lead scalable microservice architecture, improve observability and resilience, and mentor teams while driving measurable cost and performance gains.

I am a senior backend engineer focused on designing and operating scalable, reliable microservices using Java, Kotlin and Go. I have led platform-level initiatives including identity platform rearchitecture, centralized API access frameworks, and reactive stack adoption to improve performance and cost.

My work has delivered measurable impact: scaling authentication to 190K+ JWTs/day with latency improvements from 2s to 18ms, saving $34K/month by replacing SMS vendors, and enabling $1.5B in annual transaction volume through product access platforms. I build tooling and frameworks—open-source CLIs, logging frameworks, and test suites—to reduce tech debt and speed developer productivity.

I prioritize Test Driven Development, observability, and resilient cloud-native architectures (Kubernetes, AWS). I enjoy solving distributed systems problems, automating platform consistency, and mentoring cross-functional teams to adopt best practices that improve MTTR, scalability, and developer velocity.
