Summary
🤩
Rockstar🎓
Top SchoolJürgen Baier is a Senior Software Engineer with 11+ years focused on rule engines, deductive databases and high-performance multithreaded systems. He has driven core database and reasoning engine development at ontoprise and now architects backend rule processing (IRIS/datalog) at Semedy using Java, C++ and SQL. His work spans in-memory index structures, negation/recursion support in rule engines, and production-grade concurrency — areas that demand both algorithmic depth and pragmatic engineering. He has led product responsibility for a small team and repeatedly translated research-grade reasoning techniques into robust commercial software. Based in Karlsruhe, he blends academic rigor from a Master in Computer Science with hands-on system building dating back to early R&D and embedded UI experiments. Colleagues describe him as someone who makes complex inference engines practical and performant in real-world backends.
