location: Bengaluru, India 🇮🇳I treat mobile apps not as static UI canvases, but as real-time, high-concurrency distributed engines. Over the last 5+ years, I've engineered systems powering India's top consumer tech products, contributed to tier-1 developer toolchains, and built ambitious 3D simulations and transit engines from scratch.
