About this gig

Backend Software Engineer (SDE-2) at Zeta, building high-scale payment and card-processing systems. Previously at Media.net, where I worked on ad-tech platforms handling 200K+ requests/minute.

I specialize in Java, Spring Boot, Apache Flink, Kafka, Redis, and AWS (S3, Redshift). Recent work includes migrating batch processing to Flink (~70% faster for 1L+ daily financial statements), building ETL pipelines with Airflow, and designing multi-tenant + Kubernetes-based systems.
