At Fidelity Investments, I owned API development for migrating Transfer of Assets from a legacy .NET monolith to Java microservices, enabling ACATS-based inter-brokerage transfers. I also built Kafka event processing with retry queues and dead-letter topics.
I designed and developed Electronic Fund Transfer APIs sustaining about 60 TPS against a 3-second SLA, and delivered 15+ production APIs across customer accounts and money movement. At BNY Mellon Technology, I built Java/Spring services for securities splitting and real-time security inquiries, and enhanced collateral portfolio services to support zero-downtime releases.
