About

I build the product — and run what it runs on.

Full stack engineer with five years across fintech, B2B SaaS, and AI products. Most recently the sole engineer at Contera AI, a Techstars Tokyo ’25 portfolio company, where I took a Google Ads automation platform from architecture to production and on to 50 paying customers.

My work sits where product meets infrastructure: Next.js and TypeScript applications on PostgreSQL, multi-stage LLM pipelines, and a self-hosted MCP server that exposes internal tools to Claude — collapsing manual campaign audits into a single conversational query.

I'm comfortable owning the parts that often get handed off: the job queue and its failure modes, Stripe webhooks and billing, the VPS and Nginx, centralized error tracking, and the query-level optimization that keeps it all fast.
