About

I'm a Principal Software Engineer with 17 years of experience building distributed systems and platform architecture at scale. Currently at Workday, where I lead architecture for Orchestrate — a suite of Kotlin and Scala microservices handling async workflow orchestration across thousands of enterprise tenants.

My work spans the full backend stack: from designing multi-tenant PaaS platforms and compiler pipelines, to async state management, auth systems, and performance engineering on AWS (ECS, Kubernetes, SQS, Aurora, ElastiCache). I thrive at the intersection of technical depth and cross-team leadership — shaping roadmaps, aligning stakeholders, and mentoring engineers across distributed teams.
