Marvellous Nwachukwu

Built an end-to-end business product for law firms: an on-chain anchored, court-admissible version history. Implemented Soliditiy-based smart contracts plus an offline-first web app where documents are encrypted in the browser, stored on Arweave, and anchored on Fraxtal mainnet. Designed workflows so lawyers never handle wallets and do not pay gas. Implemented idempotent commit queuing and client-generated IDs to ensure anchoring cannot be double-issued and remains irreversible. Added multi-tenant firm-level organizations, role-based access, ethical walls, and time-limited sharing links for opposing counsel.

Worked on KRWQ, a Korea-based stable-coin project built with Frax and IQAI, live on six chains with 100% asset backing. Implemented Frax Net P2P for USDT/USDC/FRXUSD and KRWQ including local fiat payment methods. Built krwq.me claimable handle pages for freelancers (work samples, tips, and payment requests), KRWQ Gift and KRWQ gift cards on Base, and KRWQ Live donation alerts for Korean streamers with server-side on-chain receipt verification before pushing alerts.

Full-stack engineering across the IQAI product suite. Built the IQAI website entry point and developed the Agent Tokenization Platform front end (agent creation, bonding-curve trading, real-time updates, search, and analytics). Rebuilt the Brain Vault web interface from scratch, implemented a DeFi vault on Frax (deposit/withdraw and P&L tracking), and created a Frax Ramp fiat on-ramp with a NestJS API, operator console, and an installable React package. Contributed to IQ.wiki, a crypto encyclopedia, and developed an internationalized white-label prediction-market platform with order-book trading, portfolio tracking, notifications, and i18n.
