I build scalable Java services, event-driven pipelines, and reliable APIs.

At HireRight, I build and operate production services that move structured data reliably across systems. I designed an event-driven RabbitMQ migration pipeline from SQL databases to MongoDB, reducing manual data handling by 80%.

I've modernized a production application from Java 8 to Java 21, built vendor-fallback workflows for external verification APIs, and improved search latency through debounced and batched API handling. I also optimized PL/SQL packages to reduce average query execution time by 25% and added structured logging for clearer production observability.

I build concurrency-safe distributed systems in Java and Spring Boot, including a Redis-backed rate limiter using the Token Bucket algorithm and Lua scripts to prevent race conditions under parallel load.
