I'm a software engineer with 8+ years of experience building tooling platforms, infrastructure, and distributed systems.
Today I build engagement data and payment platforms at Sony Engagement Platform Services, a new Sony Group company.
Before that: API platforms and SDKs at ClickUp, and full-stack internal tools for PlayStation cloud gaming.
Most of my work is in TypeScript, Java, and Go on Kubernetes and AWS, backend through frontend. I build with LLM-agent workflows across Codex, Claude, and Cursor.
