“Systems-focused C++ engineer who built a 32-bit CPU simulator end-to-end (custom ISA, full memory model, fetch-decode-execute loop) and solved tricky recursion/stack-frame correctness issues through heavy instrumentation and tracing. Has strong Linux and user-kernel boundary experience (procfs) plus modern build/test tooling (Docker, CI/CD, pytest), and is confident ramping quickly into ROS/ROS2 despite not having used it directly.”

“Frontend-focused developer with startup/co-op experience who ships end-to-end UI features—from Figma/Canva designs to JavaScript/React implementation. Notably refactored a Bootstrap codebase to fix tablet responsiveness across every page in ~1–2 weeks, improving maintainability via semantic HTML and cleaner CSS organization. Built a React + TypeScript movie-tracking app using Firebase auth and Context-based user state, incorporating user feedback and pragmatic QA practices.”

“Frontend/mobile engineer with iOS and React/TypeScript experience who built an app (Tokidos) from proof-of-concept to production at Neuronic Works Inc.
