“Arem took our exam prep concept from idea to launched platform in 8 weeks. 250+ students active in launch week, 87% retention through exam date. He thinks like a founder, not just a developer.”

I build systems that connect all your different tools together so nothing breaks once you start scaling up.
I build things that make it easier for your customers to find you, trust you, and actually buy from you.
I build products end to end — from architecture to shipped code — so you get outcomes, not just output.
I build products end to end, from architecture to shipped code. I also write about self-custody and DAO tooling.
Six lanes of work, each with a track record behind it. The projects list and client words further down are the receipts.
Tutorials and field notes that turn working code into something the next person can follow.
End to end builds: schema, API, UI, auth, payments, and the deploy after.
Scoping and sequencing, the decisions that decide what ships this week instead of next.
Multisig, self-custody, and DAO tooling, explained and deployed in the same breath.
Interfaces and design systems built to stay consistent as the product keeps growing.
Third-party services stitched in cleanly: payments, auth, data, and the edge cases between.
Why me
Here is the honest version. Plenty of people can write code. Fewer people can take a rough idea, own the whole thing end to end, and actually ship something that works and makes you money, without disappearing halfway through or running way over budget. That is the part I actually care about.
I do not just build what is asked for, I figure out what the business actually needs first, build it clean enough to grow instead of breaking the moment it gets real traffic, and stay on it until it is genuinely working, not just handed off and forgotten. If you want someone who treats your problem like it is their own problem, that is me.
Below are a few of my many projects.

Dr. Adebayo
Founder, Propeida
“We hired Arem for a fractional CTO engagement. In 90 days: migrated legacy React to Next.js 14, cut bundle 40%, set up CI/CD with preview deployments. Shipped 3 major features on schedule.”
Sarah Chen
CTO, Stealth HealthTech
“Our new clinic site went live in 3 weeks. Booking inquiries up 3x first month. Patients specifically mention the doctor profiles and 4-step process — they trust us before they call.”

Work history, current and previous, with the stack each role ran.
Building Propeida, an entrance exam prep platform (formerly PrepIQ). I own the product, the architecture, and the engineering.
Self-employed
Contract work across fullstack and product engineering: dApps, dashboards, and client sites, scoped and shipped end to end.
University of Ilorin
Studying electrical engineering. The coursework feeds directly into the product work: signals, circuits, and systems thinking.
I can help. Whether it's a web app, a product, or something in between, I'm down to work on it. Email is the reliable channel. X works if you are already there.
These projects, with their current status. The status column is part of the information, not decoration.
Launched
Launched. UNILORIN Post-UTME is the first supported exam.
General entrance exam prep platform, rebranded from PrepIQ. Practice questions, per-exam leaderboards, referral tracking, and admin question management.
Did not win
Did not win. A submission-blocking SDK version mismatch prevented the deposit flow from completing; documented in the submission rather than hidden.
Non-custodial stablecoin privacy app built on Monad for a hackathon. ZK privacy layer for private balance management, client-side duress mode.
Postponed
Postponed. Pending equipment funding.
B2B SOC 2 compliance orchestration platform. Tenant-aware architecture with enterprise pricing tiers.

Not a biography. The route from circuits to products, and why the writing came with it.
I came to software through electrical engineering. Circuits and signals taught me that nothing fails without a reason, and that the reason is usually findable. I carried that instinct into code, and it has not let me down since.
The writing came from the building. Every time I worked a problem out to the end, I wrote the note, then tightened it into a tutorial. The answer is the easy part. Keeping the reasoning is the work.
Propeida started as that same instinct pointed at my own situation: exam candidates with no reliable practice ground. It is now a product with accounts, payments, and leaderboards. I build the way I study, one layer at a time, checking the load at every step.
