As a former team leader and lecturer with Silicon Valley experience on his GitHub bio, he brings an entrepreneurial mindset and an ability to communicate technical ideas clearly. Currently seeking opportunities as a Junior JavaScript developer, he offers the curiosity and broad exposure of a self-directed engineer who repeatedly bridges between UI, engine internals, and backend robustness.
