What I'm looking for

I'm looking to build secure, scalable, high-availability platforms that improve customer experiences and operational reliability, especially across healthcare, fintech, APIs, and distributed systems.

At VillageMD, I led the design and development of scalable healthcare and telehealth platforms supporting virtual care workflows for patients and providers.

I architected a real-time virtual waiting room for patient check-in, provider coordination, and appointment management. I also designed event-driven microservices, integrated third-party healthcare systems, and advanced platform reliability, performance, and observability.

Previously at Walmart, I developed and maintained API Gateway capabilities including authentication, authorization, traffic routing, rate limiting, monitoring, and service integrations for distributed internal and external services.

Earlier at FIXER, I built secure fintech and internal management systems for Japanese banking clients, including Hokkoku Bank.
