About

Hi, I’m a Mobile Engineer with 3+ years of experience building high-performance, scalable applications using React Native and React.js. I specialize in real-time systems, AI-driven user experiences, WebSocket-based communication, and production-grade mobile architecture. I’ve worked across both product and enterprise environments—Futuristic Labs (Klynk) and Cognizant—owning end-to-end development of core features, optimizing performance, and improving app reliability at scale. My experience includes: • AI-based guided cooking with Whisper (OpenAI) + LLaMA (Meta) • Real-time IoT interactions with induction cooktops • ONDC integration for live ingredient delivery • CI/CD automation for faster and stable releases • WebSocket optimization with 95% stability improvement • Large-scale UI refactoring and component standardization • Performance tuning, reducing crash rates and load times significantly I enjoy building intuitive, reliable, and highly optimized mobile experiences. My approach combines strong engineering fundamentals, clean architecture, and a deep focus on user impact. Currently exploring opportunities where I can contribute to high-impact mobile and web teams, solve complex problems, and work at scale.
