The Challenge

Joined a startup as technical lead to build a knowledge-management platform. Small codebase, no infrastructure, an aggressive timeline — every architectural decision was mine to make and own.

What I did
  • Architected and built the full stack: a React / Next.js frontend, a Hono RPC backend, and PostgreSQL with Drizzle ORM.
  • Stood up the entire cloud setup on Hetzner Cloud with Kubernetes, CI/CD pipelines, and automated testing.
  • Integrated LLM features end to end with the AI SDK, designing the prompt flows and streaming UX.
  • Adopted an AI-first workflow for code review, refactoring, and rapid iteration on complex features.

An enterprise aviation client ran a business-critical application on aging .NET WebForms. I was brought in to define and lead the migration to a modern Angular frontend.

What I did
  • Defined the migration strategy and target architecture for the new Angular frontend.
  • Drove the key technical decisions and set the patterns the team built on.
  • Prioritized technical excellence and performance from the start.
