SuperLauncher: full-stack work on an IDO launchpad and staking platform

I was a core member and full-stack web developer on SuperLauncher at BlockDevs (Feb 2020 to Jan 2022), an IDO, staking, and marketplace platform: the Node.js and Express backend, The Graph subgraphs, and a custom Vue 3 wallet module.

SuperLauncher is an IDO, staking, and marketplace blockchain platform. An IDO is an Initial DEX Offering - SuperLauncher was an IDO launchpad. I was a core member and fullstack web developer from the start of the project, at BlockDevs, with the project running Feb 2020 to Jan 2022.

What I shipped

Core member on a blockchain platform spanning IDO launches, staking, and a marketplace. I set up the platform architecture - Node.js/Express backend and web app - with REST APIs, auth and sessions, PostgreSQL schema and queries, and The Graph subgraphs with GraphQL for on-chain data.

How I worked

I set up the platform architecture, developed a custom blockchain wallet module for Vue v3.x, contributed bug fixes to the WalletConnect open-source project, maintained platform stability and resolved UI issues, conducted code reviews, and maintained code quality standards.

The wallet module

I built a custom blockchain wallet module for Vue 3. It integrated MetaMask, TrustWallet, Safepal, Solflare, and Onto via WalletConnect, Web3.js, and Ethers.js.
