Software Engineer at Sony | Building Full Stack Systems | Open Source Contributor | SIH 2020 Winner 🏆

About

I'm a software engineer who splits my time between cross-platform mobile apps and backend GenAI systems, both in production. On mobile I work in React Native: shipping new product surfaces, accessibility, feature-flagged rollouts, and increasingly edge AI inside the app. On-device inference, model integration at the client layer, and making AI features feel native rather than bolted on. On the backend I build the systems that support that: REST APIs, event-driven pipelines, and LLM observability that tracks latency, token usage, and errors once agents are live. Python (FastAPI), Node.js, PostgreSQL, RabbitMQ. Plus RAG pipelines, multi-agent workflows, and tooling that solves a real problem instead of looking good in a demo. I care about the full path from model to user: ingestion and persistence on the server, visibility when something breaks at 2am, and a mobile experience that doesn't fall apart under real network and device constraints. Code should be functional and maintainable. The kind that doesn't turn into a nightmare three months later. Open source contributor. SIH 2020 winner. Shipping under pressure is its own skill.
