About
Build it. Then teach it.
B.Sc. Computer Science, Ignatius Ajuru University of Education, 2014–2018. CGPA 4.09 / 5.0.
I started writing software in Port Harcourt a little over a decade ago. The early years were product work: React apps, APIs, admin dashboards, the usual full-stack mix. Around 2020 I moved into Ethereum and Solana. In 2022 I started Dapp Mentors because too many people were stuck on half-finished tutorials and had nothing to show for it.
The teaching load is real. 5,800 people in the Discord. 140 YouTube videos. 45 technical articles on Dev.to, Medium, and HackerNoon. Three paid courses that run about 10, 12, and 20 hours. I also wrote developer courses for the DFINITY Foundation and the Sia Foundation, taking people from a blank editor to a project on a public network.
I still ship. OpenBench, Rebit, RumbleCourt, and dappmentors.org are systems I designed and built, not slide decks. Build it, then teach it. That loop is the whole practice.

Selected work
Things I designed, built, and put in front of people
Filter with the role chips at the top if you only want frontend, AI, chain, DevRel, or teaching.
OpenBench
2026
An AI dataset curation platform with a nine-stage pipeline. CrewAI agents probe each task, an LLM judge scores on 11 criteria, and every approved artifact is stored on Sia so anyone can fetch the CID and check it. I built the Next.js frontend (passkeys, role-based admin, a first-run setup wizard) and the durable pipeline behind it.
- Next.js 16
- TypeScript
- FastAPI
- CrewAI
- Inngest
- Sia
- PostgreSQL
Rebit
2026 · In development
A self-hostable video engine that cuts long videos into short vertical clips. Whisper and Ollama run on the operator’s machine. No cloud AI API. Outputs go to Sia. Docker Compose, a setup wizard, and a job tracker that shows each stage as it happens.
- Next.js
- FastAPI
- Whisper
- Ollama
- FFmpeg

RumbleCourt
2026
A live multi-agent debate: two LLM advocates, a judge, streaming output, and on-chain records. Built for the Commit To Change AI Agents Hackathon. FastAPI for the agents, Next.js for the room, Solidity for the record. Re-renders dropped about 40% after a state pass.
- Next.js 16

Timeless NFT
2022
An NFT marketplace with Solidity ERC-721/1155 contracts for minting, listing, bidding, auctions, and royalties. IPFS metadata, OpenSea-compatible, MetaMask in the UI. Hardhat tests, then Ethereum and Polygon. About 30% less gas after a contract pass. 46 stars on GitHub.

Teaching
Dapp Mentors, YouTube, and a Discord that answers back
I started Dapp Mentors in 2022. The point was simple: stop leaving people with a 12-minute video and no project. Courses end in something you can deploy. The Discord is where the leftover questions go.

Writing
Technical writing that ends in something you can run
About 45 articles across Dev.to, Medium, and HackerNoon. Most of them walk through a system I actually shipped: a contract, a RAG path, a wallet flow. The same habit as the courses. Explain the work by showing the work.
