Now at Silo Fortune, previously NVIDIA

M V Nihal Narayan Rao.

I took Kissan Sampurna from an empty repo to Google Play, where 2,100+ farmers use it every week. I also wrote notifkit.dev, an open-source notification engine that sends 7.8M+ notifications a month at Silo Fortune.

Experience

Where I have worked

Aug 2025 to present

Software Engineer @ Silo Fortune

Built a custom real-time voice agent in 12 Indian languages. Speech-to-text and text-to-speech run on the phone, and answers come from a RAG pipeline on pgvector. Moving speech on device cut voice cost from ₹3 a minute to ₹0.01 a minute.
Built the backend for gausampurna.com in Node.js, TypeScript, PostgreSQL, and Redis for 30K+ monthly users, with distributed cart locking to prevent checkout race conditions, Cashfree payments with HMAC-verified webhooks, CRM and ERP sync, and typo-tolerant search in 8 languages.
Built and launched the Kissan Sampurna React Native mobile app from an empty repository to Google Play. It has 2,100+ weekly active farmers.
Replaced Expo EAS Update with a self-hosted over-the-air update server on Cloudflare R2 and D1 that ships delta-patched JS bundles with staged rollouts, cutting hotfix turnaround from 7 days to about an hour.
Deployed notifkit, my open-source project, as the company's notification infrastructure. It delivers 7.8M+ notifications a month across 8 channels.
Built crop recommendations from soil health, weather forecasts, and live market prices, plus satellite field monitoring (water stress, growth, nitrogen and nutrient levels), photo-based crop disease detection, and mandi price forecasting.

Feb 2025 to Jul 2025

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.

Nov 2024 to Feb 2025

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.

featurekit

open-source feature flags

A self-hosted feature flag platform. An in-memory rule engine evaluates targeting rules, user segments, and percentage rollouts with zero network calls per check. Flag changes reach apps in real time over Server-Sent Events, and apps keep working on the last known good snapshot if the control plane goes down.

npm packages

# install server & client packages:
$npm i featurekit-server
$npm i featurekit-client

Packages: featurekit-server, featurekit-client
Evaluator: In-memory, zero network calls per check
Security: Client SDKs get evaluated values only; HMAC-signed user contexts
Runtimes: Browsers, React Native, Node.js, Deno, Bun, edge
Bucketing: Deterministic murmur3, cross-language conformance tests in CI
Built with: TypeScript, Drizzle ORM, Postgres, Redis, Zod

About

A bit about me

I work at Silo Fortune, where I build backend services and low-latency voice AI pipelines. Before that, I built GPU test automation agents at NVIDIA and a mobile trading app at AltQube.

Outside work I maintain open-source projects: notifkit.dev, featurekit, and truecaller-react-native.

I studied Information Science and Engineering at Ramaiah Institute of Technology in Bengaluru, graduating in 2025.

I am open to engineering roles, contract projects, and collaborating on open-source software.
