## about

At Kuupanda, a platform that helps local food producers sell directly to buyers, I built the producer mini-sites, the customer order form and checkout, and the back-office purchase invoicing and customer messaging.

As CTO of Podder I built the entire podcast analytics platform end to end: cross-promotion tracking on Cloudflare Workers, audience personas, Beam pipelines into BigQuery, a NestJS API and React dashboard, and an MCP server for AI agents.

AI in production: audience personas, review insights, an in-app assistant and an MCP server, built with the Vercel AI SDK on Claude and OpenAI models.

I care about type safety, test-driven development and domain-driven design.
