At BlackRock's Aladdin Post Trade platform, I develop Java and Spring Boot services that generate, validate, and process SWIFT payment messages for investment settlement workflows. I delivered ISO 20022 MX enhancements alongside legacy MT103 formats and strengthened validation of clearing codes and payment fields.
At Paul Merchants Ltd, I led backend development of a gold loan management platform covering loan accounts, interest calculations, and repayments. I integrated Razorpay for online interest payments and implemented OTP verification and REST API security with Spring Security and JWT.
I also built backend services for Bandhan Bank's DIY savings account-opening journey and developed an ISO 20022 AI Assistant that validates MT103 messages and converts them to pacs.008 XML. The project uses RAG to explain validation errors and Redis to cache answers.
