Currently
Frontend engineer at Pagrin, shipping interfaces for Tita Group, maintainer of open-source SDKs, and proprietor of a school in Jos, Plateau State. I build at the seam of software, business, and education — and I write code with Claude Code in the loop every single day.
About
I build things that have to work — in production, and in the real world that leans on them. Code that ships to users. Businesses that have to make payroll. A school that opens its doors every morning. I live at the seam where engineering meets ownership, because that's where software stops being a demo and starts changing how people earn, build, and learn.
01 · Engineering
Five years of building production software across web, Web3, and AI-native tooling. Frontend engineer at Pagrin, where I design and ship the interfaces — partners dashboard, embeddable web SDK, shared AI chat and analytics packages — across a multi-app Turborepo. Maintainer of Rabit, a MIT-licensed embedded wallet SDK with non-custodial key recovery.
02 · Operating
Inside Tita Group I've built TitaCenter (fintech: on-ramp, off-ramp, exchange, invoicing, wallet) and Stim (real-money Web3 PvP gaming on Base). I know what it takes to spec, ship, and operate a product, not just write the code. That perspective shapes every interface I design and every architectural decision I make.
03 · Education
Firm Foundation & Dominion Academy is one institution in Jos, Plateau State — nursery and primary, with a secondary section we just opened. My parents founded it; I recently took on its proprietorship, bringing the same systems thinking I use in software to running it. In my own time I'm building SkoolBox, an offline-first AI tutor in Tauri + Rust, so children with intermittent internet can still learn with AI in the room.
Selected work
Frontend engineer · Pagrin
Partners dashboard + embeddable web SDK on a multi-app Turborepo with shared AI chat, analytics, and i18n packages.
Two product surfaces ship from one source of truth. Designed and shipped the partners dashboard UI, the embeddable web SDK, and the shared design system that powers both.
Lead frontend engineer · Tita Group
Fintech super-app: on-ramp, off-ramp, exchange, trade, invoicing, payment-gateway, and wallet — one product, one team.
Shipped seven financial product surfaces inside a single coherent interface. Built the design system, animation language, and data-fetching patterns the rest of the engineering team now extends.
Full-stack engineer · Tita Group
Real-money Web3 PvP gaming PWA. Tic-tac-toe in USDC on Base, with a minimax AI fallback when no opponent is online.
Wallet-connected PvP, real-money escrow, minimax + alpha-beta AI for solo play, full-stack i18n, PWA installability. Shipped admin panel separately on Next.js + wagmi.
Creator · Maintainer · Open source
Open-source embedded wallet SDK. 11-package Turborepo, EVM + Solana, 2-of-3 Shamir Secret Sharing for non-custodial recovery.
MIT-licensed SDK with a `create-rabit-app` scaffolder, full CONTRIBUTING / SECURITY / CoC, and key recovery that doesn't require a custodian. The wallet layer that should have existed.
Product engineer · Foniolabs · school pilot
Offline-first AI tutor for Nigerian classrooms with intermittent internet. Tauri 2 + Rust + local LLM. Built under Foniolabs, designed for the school I run.
A ~12MB desktop app that gives teachers AI-assisted lesson planning and students an AI tutor — without depending on the internet. Pilot deploys into the school I run.
Founder · solo build · Personal lab
My personal lab for tech in education and web3. Migrated its site to Sanity + Next.js with Claude Code MCP wired into the editor flow.
I publish content by prompting Claude Code. Lighthouse 95+ across the board, zero SEO ranking drop after DNS cutover.
Stack
Leadership & Education
Code is one half of my work. The other half is operating Firm Foundation & Dominion Academy — the school my parents founded in Jos, Plateau State — with the same rigor I bring to a codebase: clear systems, observable outcomes, and tools that let small teams move like large ones.
Proprietor · since 2026
Jos, Plateau StateThe established core of Firm Foundation & Dominion Academy, founded by my parents. I recently took on its proprietorship — bringing systems thinking to admissions, reporting, parent communication, and modern classroom infrastructure.
Proprietor · since 2026
Jos, Plateau StateThe newest section of the school, launched this year. Standing it up means owning the academic calendar, faculty operations, and piloting SkoolBox as the in-classroom AI tutor.
Operating principles
01
I don't design for users I haven't observed. Every system I ship gets used by people I can name — students, partners, marketing operators, traders.
02
AI-native tooling lets a small team operate like a large one. Claude Code is in my flow every day; on Foniolabs, my personal lab, Sanity MCP runs the publishing pipeline so I ship content by prompting. The leverage is real.
03
SkoolBox is offline-first because the school that needs it most doesn't have reliable broadband. TitaCenter speaks Naira-first because that's where its users live. Constraint becomes feature.
In the field
Timeline
Proprietor · Jos, Plateau State
Took on the proprietorship of the school my parents founded — nursery, primary, and a newly opened secondary section. Running academic operations, faculty oversight, and piloting SkoolBox, an offline-first AI tutor I build in my own time, as in-classroom infrastructure. Treating school operations like a product: clear systems, observable outcomes.
Frontend Engineer · Remote
Lead the frontend across a multi-app Turborepo: partners dashboard, embeddable web SDK, and the shared @pagrin/ai-chat, /analytics, /i18n, /ui packages. Designed and shipped the dashboard interface, the embeddable SDK surface, and the i18n + analytics pipeline that powers both apps.
Senior Frontend Engineer · Remote
Lead frontend across Tita Group's product portfolio. Shipped TitaCenter (fintech super-app — on/off-ramp, exchange, invoicing, payment gateway, wallet) and Stim (real-money Web3 PvP gaming on Base, plus a separate Next.js + wagmi admin panel). Built the animation language, design tokens, and data-fetching patterns the engineering team extends.
Founder — Personal Lab · Personal project
Foniolabs is my personal lab — where I experiment with tech for education and web3 in my own time. Most recently I migrated foniolabs.xyz to Sanity + Next.js + Vercel: 9 document types, 8 reusable section blocks, custom Studio components (slug-with-auto-redirect, SEO preview, OG preview, presentation tool), and Claude Code + Sanity MCP wired in so I publish content by prompting. Lighthouse 95+ across the board.
Full-Stack & Web3 Engineer · Jos, Nigeria
Built and maintain Rabit, a MIT-licensed embedded wallet SDK with non-custodial Shamir-based key recovery — 11 packages, EVM + Solana, `create-rabit-app` scaffolder. Earlier: shipped wallets, on/off-ramps, PvP dApps, and fintech tools for clients across Africa and Europe.
