I build scalable backend systems and developer-focused platforms with a practical, results-driven approach. My work blends Java and Spring-based microservices with event-driven architecture to deliver resilient APIs and production-ready deployments.

As a co-founder and developer, I shipped a TypeScript web app using GPT-4 for AI-driven resume rephrasing, job matching, and dynamic voice interviews, and implemented client-side PDF parsing into editable JSON to streamline resume ingestion.

On infrastructure and platform work, I designed a multi-tenant authentication and authorization platform featuring RS256 JWT signing, JWKS endpoints, Kafka-based event streams, Redis-backed rate limiting, Resilience4j for circuit breaking, and thorough JUnit/Mockito test coverage.

I enjoy solving system design challenges—dispatch optimization, geospatial assignment using the Haversine formula, modular strategy patterns, and observability—while learning quickly and iterating to ship reliable MVPs and production services.
