Introduction
Overview.
Software engineer with over 10 years of experience, from game server systems written in Lua and C++ to full stack web applications. I have spent most of that time on live production systems where stability matters, working across C++, Lua, PHP, MySQL, TypeScript and React. I care about clean architecture, performance and code that stays readable and maintainable long after the first release.
