About

I’m a backend Java developer with 5+ years of experience building and scaling enterprise applications. My core expertise lies in Java, Spring Boot, and microservices, with a strong track record of migrating payment applications from monoliths to microservices—improving scalability, performance, and reliability. Beyond backend systems, I’ve also worked on data engineering projects, including migrating large-scale pipelines from Hive to BigQuery for people and places data. This combination of backend and data engineering experience allows me to bridge the gap between application logic and data infrastructure, ensuring end-to-end efficiency. Currently working with Amazon Business (MCS team), I thrive in solving complex technical challenges, collaborating across teams, and delivering systems that scale.
