What I'm looking for

I'm looking to build scalable, low-latency backend and data-processing systems, particularly in financial systems where reliable reconciliation, data integrity, and high-throughput transaction processing matter.

At Paytm, I build high-throughput financial data pipelines that process more than 45 million Payment Gateway transactions each day.

I architected an asynchronous, multithreaded ingestion pipeline that reduced data dump time from three hours to 40 minutes while improving memory utilization. I also develop Java and Spring Boot batch systems focused on low-latency processing and stability under load.

I own daily payout reconciliation pipelines handling 18 million transactions per day and build backdated reconciliation workflows to recover missed transactions and maintain accurate settlement with nodal banks.

I’ve built 20+ finance reporting modules with OpenSearch and MySQL, and use Grafana and Kibana monitoring to detect mismatches and protect data integrity. I also enjoy building backend systems for transaction analytics and scalable data processing.
