My professional journey in blockchain and full-stack development

Fullstack Blockchain Engineer

Grumble Studio

Aug 2025 - Dec 2025

Remote

Led end-to-end development of a real-time world map game — designed system architecture, built the Next.js frontend, and implemented a NestJS + Prisma + PostgreSQL + Redis backend optimized for performance, scalability, and low-latency interactions.

Shipped room-based real-time chat using Supabase Realtime, Redis Streams for message queuing, and background workers for persistence and data seeding, ensuring high reliability under real-time load.

Built RugRumble, a Web3 gaming platform, where I:

  • Designed and implemented upgradeable EVM smart contracts
  • Developed the fullstack application using Next.js, NestJS, and Supabase
  • Implemented on-chain data indexing using The Graph (subgraphs) for efficient querying and real-time updates
  • Handled complete smart contract ↔ backend ↔ frontend integration
