I build secure Java microservices for high-volume banking, payments, and ride-sharing platforms.

I've built Java/Spring microservices for UCBL and ABBL internet banking platforms serving 2 lakh+ users, delivering bulk payments, fund transfers, Visa card transactions, and account management.

At Brain Station 23, I architected the Khajna tax/VAT system and ABG Wallet with Java 17, Spring Boot, JHipster, Redis, Kafka, and microservices. I also managed Jenkins CI/CD pipelines and SSL updates for City Bank to reduce deployment downtime.

I'm currently implementing User, Driver, and Fare Calculation microservices for a ride-sharing platform at Technonext Software, using Java, Kafka, Redis, and Cassandra for high-performance real-time processing.
