Principal Software Engineer and Open Source Maintainer with 7+ years of experience as a core contributor to open source platforms. I'm a versatile full-stack developer with deep experience in backend architecture, distributed systems, and building complete data/ETL pipelines.

Beyond coding, I am focused on creating business value and bridging the gap between engineering, customers, and operations. I recently led the end-to-end delivery of a multi-tenant B2B compliance SaaS that tracks over 50M retail-ready units per month. I have also authored 10 comprehensive technical proposals for state government projects and deployed an OpenClaw agentic AI system into a phone-support CRM that slashed agent recovery time by 75%.

I'm looking for a senior to principal-level role where I can solve complex technical challenges and drive business value.
