At Hackberry Technologies, I build backend workflows and APIs for a Python retirement-services platform that manages mortgage-backed securities for institutional investors. My work covers transaction processing, security validation, and portfolio data.
I define and validate business rules and data requirements for UMBS, Supers & Giants, and REMIC products. I also troubleshoot cross-system data issues and resolve workflow defects to support testing and production readiness.
At Google, through HCL, I improved application search performance by 78% and cut infrastructure costs by 23% through API, schema, and query changes. I also built automation tooling across Spanner and BigQuery that eliminated manual work and permanently resolved data-consistency failures in multi-database services.
My other work includes REST APIs and an executive reporting dashboard at Verizon, plus PostgreSQL and AWS S3 ETL pipelines at Mindtree. I also built an open-source Fintech Wallet Service with a double-entry ledger, optimistic concurrency control, and idempotency keys.
