Senior Software Engineer at Sofy.ai building Java microservices and a Kafka-based platform for enterprise clients.

At Sofy.ai, I built the Java and Spring Boot microservice architecture behind the platform, with Kafka events and REST APIs used by clients including Royal Caribbean, SeaWorld, AllTrails, and SAP. I also built real-time mobile-to-browser streaming that cut lag from 2 seconds to 800 milliseconds.

At Snoonu, I tech-led three teams while writing about 30% of the code, and built an event-driven Order Service and Operations Portal. The work cut operational costs by 28% and order latency from 30 seconds to 14 seconds.
