I build secure, scalable web services and identity platforms for regulated, high-volume products.
United StatesWhat I'm looking for
I've built secure web applications, identity platforms, and data-handling services for Memorial Sloan Kettering Cancer Center, Expel, and Fidelity Investments.
At Memorial Sloan Kettering, I delivered identity and access management features for a clinical portal serving 12,000+ staff. I built self-service React and Redux administration workflows, automated provisioning through SCIM, and reduced manual access requests by 35%.
At Expel, I developed Go and Python microservices for subscription and access APIs serving 30M+ monthly active users. I modernized AWS workloads, strengthened API reliability with gRPC, and led a configuration-service consolidation for six downstream teams.
At Fidelity, I built Python services and event-driven clinical trial workflows that reduced manual chart review by 35%. I enjoy shipping reliable systems in regulated environments, mentoring engineers, and partnering across product, security, compliance, and design.
