What I'm looking for

I seek senior engineering roles building secure, scalable cloud-native products (healthcare/fintech), with strong emphasis on observability, compliance, and team leadership.

I am a results-driven Senior Software Engineer with 8+ years building scalable, secure cloud-native systems for digital health and fintech. I design domain-driven microservices, lead cross-functional teams, and deliver full-stack solutions—improving latency, availability, and developer velocity across AWS, Kubernetes, and modern CI/CD pipelines.

My work spans front-end (React/Next.js/TypeScript, Angular) and back-end (Java/Kotlin, Go, Python, Node.js) stacks, event-driven architectures (Kafka, SNS/SQS), and AI/data tooling. I prioritize observability, security and compliance (HIPAA, PCI-DSS, SOC 2), and have repeatedly driven measurable improvements in Core Web Vitals, p95/p99 latency, deployment frequency, and operational cost savings.
