Hi, I’m Sujan Bhattarai, a senior cross-platform mobile app architect and full-stack engineer with 5+ years of hands-on experience delivering large-scale deployments, backend microservices, and performance-optimized engines. I specialize in Flutter and Dart for mobile development, and I scale corporate cloud systems with PHP and Laravel. I also build low-latency native C++ bindings through Flutter FFI and OpenCV-powered pipelines to maintain fluid 60fps render loops while protecting user privacy on-device. I’ve led organic growth through ASO/SEO strategies and designed end-to-end ecosystems such as multi-tenant CRMs and POS integrations. I thrive on turning complex requirements into robust software architectures, guiding teams through Agile processes, and delivering reliable software from inception to production.
