Summary
👤
Senior🎓
Top SchoolAndrew Hauptmann is an Industrial Technology teacher with 11 years of experience combining hands-on classroom instruction and a strong background in systems-level software maintenance. Certified to teach PLTW courses including Introduction to Engineering Design, Physics of Engineering, and Digital Electronics, he brings practical engineering practice into secondary education in Waukee, Iowa. Outside the classroom he contributes to low-level open-source projects—fixing cross-platform bugs and memory leaks in widely used libraries like libuv and core OCaml—demonstrating deep familiarity with concurrency, I/O, and Windows/Unix interoperability. That mix of education and systems troubleshooting gives him a rare ability to translate complex platform-level issues into teachable lessons and reliable, pragmatic fixes.
