Delivered cross-platform applications across fintech, healthcare, aviation, ecommerce, and SaaS domains, with experience leading features, reviewing code, and owning production deployments. Currently building InspectSync, an offline-first field operations platform with synchronization, conflict resolution, and AWS media pipelines, while also developing Paari.online — an AI-powered job matching platform built with React and Node.js. Core strengths include: • Flutter and cross-platform mobile engineering • Backend systems with Node.js and PostgreSQL/MySQL • AWS cloud services and deployment workflows • Offline-first architecture and synchronization systems • Product ownership and scalable engineering practices I enjoy solving real engineering problems and building reliable systems that create measurable user impact.
