What I'm looking for

I seek engineering roles focused on distributed systems, reliability, and modernization where I can mentor teams, improve observability, and build secure, high-throughput financial or healthcare platforms.

I am a Staff Full-Stack Engineer with 11+ years building and operating critical financial and healthcare platforms, specializing in distributed systems, event-driven architectures, and regulated environments (PCI/HIPAA). I have led modernization efforts—migrating legacy scheduling to Kafka, architecting retry orchestration services, and integrating ML into payment flows—to improve reliability, reduce incidents, and increase developer velocity.

I focus on production reliability, observability, and developer mentorship, having supported on-call rotations, defined monitoring and tracing standards, and coached engineers in typed Ruby and distributed system design. My work spans backend system design (Go, Ruby, Java), full-stack React/TypeScript interfaces, and secure API design, delivering measurable reductions in defects and incident recurrence while enabling scalable merchant workflows.
