Rehan Q is a senior software engineer with a rare combination of systems-level C++ expertise, modern frontend architecture, and AI platform development experience. He has worked extensively with large, production C++ and Qt codebases, resolving critical stability, performance, and integration issues in native and JNI layers to unblock hardware product launches and ensure reliable metrics and device communication. At Precor, he operated across C++, Android AOSP, Kotlin services, and React-based web overlays, designing IPC architectures with AIDL and Android Intents, implementing accessibility- and RTL-compliant features, and integrating hardware inputs such as HDMI and camera feeds into native applications. In parallel, Rehan has led and delivered complex web and AI systems using React, Next.js, ReScript, and TypeScript, including spearheading the frontend architecture of a no-code RAG platform and building HIPAA-compliant medical chatbots using OpenAI APIs, RxJS, and state management patterns optimized for correctness and maintainability. His experience also includes backend and platform work with F#, .NET Core, Giraffe, Stripe billing, CI/CD pipelines, Docker, and Linux, as well as advanced browser-based 3D rendering with WebGL and React-Three-Fiber. With a strong engineering foundation and a systems-first mindset, Rehan consistently bridges low-level native software, AI-driven platforms, and high-performance user interfaces to deliver robust, scalable, and production-ready solutions.
