LLM platform

LLM at scale

Architected and implemented LLM integrations used across all products of a YC startup. Reliably needs to serve, store and monitor all LLM requests. Built and validated prompts for all core workflows using human-in-the-loop and LLM-as-a-judge techniques.

  • • 20+ complex prompts created and validated
Healthcare AI

German healthcare AI

After delivering several AI tools to a healthcare company, I was hired to rapidly build a MVP that integrated those and assisted users in a complex medical coding workflow. This system ended up being marketed and sold and was used in production for years.

  • • Outlier detection and predictions on medical data
  • • Working with domain experts to understand and automate their workflows
  • • Handover of the system to the in-house dev team
Product leadership

Zero → one → many

Led initial development of two product offerings for a YC start-up, one long-term. From discovery calls and scoping, over coding to onboardings and ongoing support. Demos of the product during development lead to 60k+$ in sales, already before it went live.

  • • Proposal generation tool
  • • AI Email management + Outlook integration
  • • Gathering customer feedback before and during development
