I take products from an empty repo to production.

What I build

• 01

  Backend & data pipelines

  Cron-driven sync jobs, batched ingest, rollups and dead-letter queues — the parts that have to keep running when nobody is watching.

• 02

  Analytics & instrumentation

  Event schemas, dedup and rate limiting at the edge, then the dashboards that make the data answer a question.

• 03

  Mobile — React Native & WebView

  Native shells over existing web apps, store releases, push notifications, and bridges that let the two halves talk.

• 04

  CI/CD & cloud

  GitHub Actions to S3 and CloudFront, OIDC instead of long-lived keys, Cloudflare Workers at the edge, and deploys measured in minutes rather than coffee breaks.

• 05

  Frontend — React & Next.js

  Server rendering, typed content layers and interfaces that stay fast as they grow.

• 06

  Realtime & integrations

  WebSocket rooms with server-anchored state and clock sync, plus Google Calendar, Zoom, Airtable and S3 — wiring systems together without inheriting their failure modes.

Selected work

• 01

  Analytics platform

  Batched, compressed event ingest with schema validation, rate limiting and batch-level dedup, feeding raw events, feature events and cron rollups into a self-serve dashboard for DAU/WAU/MAU, funnels and per-user timelines. Replaced a paid third-party tool.

  • Node.js
  • Express
  • MongoDB
  • Redis
  • React
• 02

  Musing — synchronized listening rooms

  A serverless app where every listener hears the same track at the same position: one Durable Object per room with SQLite-backed WebSocket hibernation, so there is no database and idle rooms cost nothing. NTP-style clock sync and drift correction hold clients within 150ms.

  • TypeScript
  • React
  • Cloudflare Workers
  • WebSockets

• 03

  Athena mobile app

  A thin native shell rendering the existing React portal in a WebView — one codebase serving browser, iOS and Android for 800+ scholars and parents, with a two-way postMessage bridge for auth, secure storage and deep links.

  • React Native
  • Expo
  • JWT
  • Push notifications
• 04

  Meeting booking engine

  Merges busy intervals across multiple consultants' Google Calendars by sort-and-sweep, then grid-scans working hours for shared free slots — auto-provisioning Zoom meetings with an audit trail and a dead-letter queue for failed writes.

  • Node.js
  • Google Calendar API
  • Zoom API
  • MongoDB
• 05

  Config-driven campaigns

  Replaced hardcoded per-banner components with MongoDB campaign documents carrying tap actions, S3 artwork behind presigned URLs and Airtable-synced targeting. A new banner went from 6–8 hours of frontend work to minutes.

  • MongoDB
  • S3
  • Airtable API
• 06

  Airtable → MongoDB sync

  A cron poller picking up record changes every 20 minutes and task updates every 10 seconds, with every read served from MongoDB instead of the upstream API.

  • Node.js
  • cron
  • Airtable API
  • MongoDB
• 07

  Blog platform

  A server-rendered blog with an admin dashboard that let non-technical users publish independently, secured with JWT auth and CSRF protection. 60% faster page loads, 50+ active members.

  • Next.js
  • MongoDB
  • Tailwind CSS

Experience

1. May 2026 — Present

   Gurugram, India

   Software Engineer

   Athena Education

   • —Built the product analytics platform from scratch — batched, compressed event ingest with schema validation, rate limiting and dedup, cron rollups, and the self-serve dashboard the team reads DAU/WAU/MAU, funnels and per-user timelines in.
   • —Engineered a cron-driven Airtable → MongoDB sync that keeps Airtable as the team's source of truth while every app read is served from MongoDB, reflecting task updates within seconds.
   • —Built a meeting-booking engine that merges busy intervals across consultants' Google Calendars by sort-and-sweep, auto-provisioning Zoom meetings with an audit trail and a dead-letter queue.
   • —Shipped a config-driven campaign system that cut a new in-app banner from 6–8 hours of frontend work to minutes.
   • —Replaced manual recording-link sharing with an in-app Zoom pipeline: cached OAuth tokens, expiring signed playback URLs and S3-hosted thumbnails.

2. Mar 2026 — Apr 2026

   Remote

   Software Engineer Intern

   Athena Education

   • —Architected and shipped the iOS and Android app as a native shell around the existing React portal — one codebase serving web, iOS and Android for 800+ scholars and parents.
   • —Decoupled UI releases from store review with a server-driven version check, so ~90% of updates ship in under 10 minutes instead of 2–3 days.
   • —Cut deploy time from 15 minutes to under 3 by automating CI/CD to S3 and CloudFront with GitHub Actions, and removed long-lived AWS keys by moving to OIDC.
   • —Built the two-way postMessage bridge carrying auth into the web layer and native secure storage, downloads, fullscreen video and deep links back out, plus push notifications routed to the right in-app screen.

3. Mar 2025 — Nov 2025

   IIT Kharagpur, India

   Founding Engineer

   Drippit — Stylai Technologies

   • —Led a 4-person team building Drippit, a React Native shopping app with 1,000+ downloads across the App Store and Play Store — owning the order pipeline end to end: placement, returns, real-time tracking and automated notifications.
   • —Co-designed the microservices backend on GCP behind a load balancer, and built the admin panel that let the operations team run the store without engineering support.

What people say

• “He joined us just as an intern and within 3 months built and deployed complex tech stacks — from React Native app to CI/CD pipeline — contributed to our groundbreaking AI search, and now owns ESOPs in Drippit.”

• “The best intern I've worked with. He picks things up remarkably fast — you explain something once and it's done. He's going to grow very quickly.”

• “It was a pleasure working with him, and I would welcome the opportunity to collaborate with him again in the future.”
