Work experience

Full Stack Developer · Kreedalabs

Pune · Aug 2024 – Present

  • Worked on Syncora — an AI data marketplace — building and maintaining frontend (React/Next.js), backend APIs (Node.js/TypeScript), and HuggingFace integrations for model fine-tuning workflows.
  • Built a Rust service (Actix-web) to stream blockchain event data to the frontend without hammering RPC nodes.
  • Wrote and deployed smart contracts (Solidity, UUPS proxy on Base L2) and a Solana Anchor program for on-chain contribution records and token rewards.
  • Integrated Stripe subscriptions and automated credit recharge flows, reducing manual billing work significantly.
  • Built React Native screens and cross-platform mobile features alongside web work.

Full Stack Developer · MixR

Remote · Mar 2024 – Aug 2024

  • Built backend services for a social commerce platform using Golang, PostgreSQL, Redis, and GraphQL.
  • Built an AI shopping agent (Vercel AI SDK + OpenAI) that can autonomously browse and purchase products on behalf of users.
  • Built MixR Pay — a crypto checkout system using Privy embedded wallets so the AI agent could handle payments end-to-end on-chain.
  • Rewrote backend APIs with agent-friendly response structures so the AI agent could reliably consume and act on them.
  • Integrated Shopify product catalog via the Rye API wrapper; added Redis caching and PostgreSQL trigram search for faster product queries.
  • Set up Docker Compose deployments on VPS with basic CI/CD; automated order and notification flows via webhooks and cron jobs.

Full Stack Developer (Freelance) · Hench Solutions

  • Shipped Mera Coach, a React Native/Expo mobile app, with EAS build setup for Android and iOS.

Full Stack Developer (Freelance) · Vyloo

Remote · 2025 – Present

  • Built a full pharmacy operations suite of five applications: customer-facing web app, merchant portal, pharmacy ERP, admin dashboard, and a shared serverless backend API.
  • Backend (Node.js/Hono) uses MongoDB, Redis, AWS S3, AWS SQS, Firebase Admin for push notifications, and Puppeteer/Chromium for PDF generation (receipts, reports).
  • ERP and customer web include Google Maps integration for delivery zone management and live location-aware order tracking.
  • Merchant portal handles real-time order acceptance, delivery workflow management, and live status updates.
  • Admin dashboard covers merchant onboarding, order oversight, analytics, and billing operations.
