Where I have worked
Software Engineer @ Silo Fortune
- Built the backend for gausampurna.com, using PostgreSQL, Redis, job queues, and distributed cart locking to prevent checkout race conditions across hundreds of daily orders.
- Built and launched the Kissan Sampurna React Native mobile app from an empty repository to Google Play with over-the-air updates.
- Integrated an AI voice assistant supporting 10 Indian regional languages with latency under 700 ms, costing under $0.50 per user for a full day of conversation.
Software Developer Intern @ NVIDIA
- Built an AI agent that parses test steps from Jira tickets, translates them into executable test sequences, and runs them autonomously on remote GPU test servers.
- Wrote a Node.js service with live terminal session streaming over WebSockets so QA engineers could trigger, monitor, and debug remote test executions in real time.
- Extended the internal Python test framework with core automation APIs and helper functions, enabling QA engineers to author and automate test suites across new hardware features.
Software Engineer Intern @ AltQube
- Built the mobile trading app in React Native and TypeScript, connecting directly to Zerodha, Upstox, and Angel One broker APIs.
- Implemented live portfolio tracking with websocket price feeds, multi-asset analytics, and interactive charts.
- Wrote a FastAPI microservice to send transactional alerts through WhatsApp, push notifications, and email.
- Containerized backend services with Docker and set up automated CI/CD pipelines on AWS.

A bit about me
I am a software engineer. I build mobile apps, backend services, and developer tools.
Currently, I work at Silo Fortune building backend services and low-latency voice AI pipelines. Previously, I developed GPU test automation agents at NVIDIA and mobile trading software at AltQube.
I also maintain open-source projects including notifkit.dev, featkit, and truecaller-react-native.
I am open to engineering roles, contract projects, and collaborating on open-source software.
