At Mastercard, I built a Spring Boot REST API for S3-backed chargeback uploads in an Axon event-driven architecture and fixed a message-consumption failure blocking status updates.
I also updated a shared cryptography library used by 5+ microservices to integrate Distributed Crypto-as-a-Service, moving cryptographic operations to a distributed architecture and standardizing AES-256-GCM encryption. At TrueFoundry, I improved multi-tenant tracing and corrected OpenTelemetry status propagation, adding 10+ TypeScript tests.
I built AI usage analytics at TrueFoundry and replaced spreadsheet-based FX holiday pricing with automated Spring Boot and SQL logic at Bank of New York. In my TaskFlow project, I built a durable PostgreSQL job queue and validated its failure recovery with a 5,000-job chaos test.
