Systems Engineer at Tata Consultancy Services building encrypted TReDS exchange integrations for SBI Trade Finance.

At Tata Consultancy Services, I built the TReDS exchange integration for SBI Trade Finance using encrypted, key-pair-signed API calls and user-wise logging for traceability and audit. I also developed features to support regulatory and business requirements, with changes checked using HP Fortify Scan.

Previously, I developed features and integrated AI-based APIs at Adbrew, and built REST APIs and dashboards at Optionlogy. At Dopamine.fit, I optimized database queries and added indexing and caching, cutting API latency from 12 seconds to 300 milliseconds.
