Projekthistorie
Co-founded an AI-native data platform for mid-market companies. Owns the architecture and roadmap. Built most of the Rust platform core including an event-sourced API, a DataFusion query engine over a Delta Lake lakehouse, and Arrow Flight SQL access for BI tools. Designed and built the LLM agent harness with tool calling, approval policies, streaming and evals, exposed as an MCP server for Claude, ChatGPT and Copilot. Built most of the React/TypeScript frontend and helped build the Kubernetes platform.
Co-developed the rewrite of a Python/Postgres data pipeline in Rust on Delta Lake achieving 80x faster performance, fewer failed runs, and reduced infrastructure cost. Rewrote a legacy XML job-sync service for Indeed as a Rust service on their new GraphQL API. Built a reporting service on top of the new Delta Lake tables.
Developed and maintained features across several full-stack web apps. Built a local service interfacing with medical hardware over serial port and TCP. Built a module for end-to-end encrypted transmission of confidential patient documents, used by many doctors practices and the Vienna Airport health centre.
