I've taken products from scratch to scale: building from day zero, stepping into mature systems, and driving growth from 0→millions of users and 10M→15M scale across very different domains and teams\. My tools change based on the problem\. I've built and shipped across native Android \(Kotlin, Java\), iOS, cross\-platform apps with Flutter, React JS, and backend systems with Node\.js and Python — choosing the right tool for the job instead of chasing trends\. My core engineering mindset revolves around architecture, system design, scalability, trade\-offs, and technical direction\. I enjoy solving complex product and engineering problems that directly impact real users\. AI is part of my daily workflow — helping me write and debug code faster, automate repetitive work, improve testing, and ship with higher velocity\. I use AI as a multiplier, not a crutch\.' With 4\.5\+ years of experience building, scaling, and shipping products across platforms, I thrive in high\-ownership environments where solving hard problems and moving fast both matter\. ## Location Bengaluru ## AI stack antigravity claude code claude gemini geminicli mcp ## Work experience Software Engineer at Roro, Oct 2025 \- Present · 11 mos, San Francisco, CA, Roro is an AI\-native product innovation studio that builds intelligent software for global clients including L'Oréal, Precision Pro Golf, and Luxer One across mobile, AI, IoT, and connected experiences\. • Contributing to highly experimental and research\-driven products across platforms\. • Turning ambitious ideas into shipped software through relentless execution\.
