[04] WEB3 ENGINEERING

Web3 / Full-Stack Engineering

The application around the contracts: React and Next.js front ends, Node.js APIs, PostgreSQL, authentication and wallet connectivity, and the integration that reads chain data into the product.

Next.js · React · Node.js · Web3

A contract is only as useful as the application in front of it. I build that application as well — the front end, the API behind it, the database, sign-in and wallet connection — and the integration that brings blockchain data into the product reliably.

This site is an example: Next.js and TypeScript on PostgreSQL, with a background GitHub sync, signed webhooks and an admin behind real authentication.
