// about me
Lisa Welsch
Founder, developer, and endlessly curious about what's next.
I'm a software developer and founder based in Vienna, Austria. I run TasteHub GmbH, where I build products that range from AI-powered developer tools to mobile apps and bioinformatics platforms.
I'm passionate about efficient code, LLMs, context compression, and cutting-edge research. I've shipped everything from low-level C++ game engines to Go-based code intelligence systems to Python bioinformatics pipelines. What ties it all together is a drive to solve hard problems with clean code — and an inability to stop learning new things.
What I Do
Developer Tools & AI
I created CKB (Code Knowledge Backend), a code intelligence system that gives AI assistants structural understanding of codebases. Semantic search, impact analysis, dead code detection, architecture mapping — 80+ tools via CLI, HTTP API, and MCP. Built in Go with SCIP indexing, supporting 10+ languages.
Game Development
I'm the lead developer and top contributor on Cytopia, a free, open-source city building simulation with 2.1k+ GitHub stars. I wrote the custom isometric rendering engine in C++/SDL2 and have 1,500+ commits on the project, managing a team of 21 contributors. I also built JewelFall, a pixel-art puzzle game for iOS.
Mobile Apps
TasteHub is a recipe management app for iOS and Android that I co-founded with Martyna. Offline-first architecture, Firebase sync, web scraping for recipe imports, and collaborative sharing. Available on both App Store and Google Play.
Bioinformatics & Science
OpenLab is an open bioinformatics platform for cancer research — autonomous AI agents that produce fully-cited gene dossiers, variant interpretation across six databases, and a public ResearchBook feed. Built on top of BioLab, which integrates genome analysis, LLM-powered evidence synthesis, and whole-cell simulation.

Beyond Code
When I'm not writing code, I'm probably cooking, gaming, 3D printing, or deep in VR. I love exploring new tech, whether it's the latest in context compression for LLMs or a new filament for my printer. Always curious, always learning.
