About
I like turning operational complexity into understandable software.
My work spans business systems, university software, healthcare products, embedded prototypes, C++ projects and games. The common thread is system design: roles, permissions, state, inventory, payments, scheduling, reporting and the rules that connect them.
I use AI tools as part of implementation and iteration, while keeping architecture, business rules, review and security boundaries explicit.
01Model the business before the interface.
02Keep critical rules close to the backend and database.
03Prefer reusable systems over one-off screens.
04Design bilingual and responsive products from the start.
