I've built corporate banking and fund-transfer systems at Intellect Design Arena and Anweb Technologies using Java, Spring Boot, REST APIs, PostgreSQL, and microservices. At Intellect, I delivered 10+ secure APIs for the term-deposit lifecycle and integrated IBM MQ consumers for high-volume core-banking transactions.
I improve reliability and performance through SQL tuning, Redis caching, resilient integrations, testing, and production troubleshooting. I reduced API latency from 5 seconds to 3.5 seconds by optimizing PostgreSQL queries and database access patterns.
