Software engineer and technical lead with 13 years building financial platforms, identity systems and high-throughput backends at JPMorgan Chase, Vanguard and Capital One. Since June 2026 I’ve worked independently: shipping products solo across mobile, real-time trading, Rust desktop tools, reverse engineering and LLM pipelines, alongside AI model evaluation contract work.
My enterprise work spans fund pricing and payments platforms, batch and messaging pipelines, credit card originations middleware, and identity governance at scale. I’ve led teams, owned delivery end to end, and been the technical point of contact for executives, security and audit. Identity is one area I’ve gone deep in, not the whole picture. Open to senior engineering roles and contract work.
