Turning real needs into AI products anyone can use.
I’m Martin Mac — working at Google after 10+ years across global tech companies. I build products that start from real needs — my own and my family’s — then refine them into webapps and apps anyone can use.

Products that start from a real need of my own
Martin Mac works at Google after 10+ years across global tech companies (Foxconn, Logitech, Google). Every product I make begins with a very real need: I needed to learn Chinese, my kids and family needed to learn English, and we all needed small tools to make studying and getting around easier. I build first for myself and my family to use — then refine and polish them into webapps, apps and content that anyone can use. The experience I gained at large companies helps me build properly: real data, evidence-based methods, and care in every detail. I believe in honest products, and I build everything end to end — design, code and content.
