MORE WORK
Every tool here has been used in production. Every skill comes with proof.
Proof · Educator at JAARC, alongside engineering.
Proof · True Worshippers Church’s team runs its own platform without a developer.
Proof · Client projects delivered with designers and other developers.
Proof · Built Buydair solo, with admin recovery tools and a deliberate ₦2,000 risk cap.
Proof · Buydair’s idempotent payments; the CBT “cannot load exam” fix; the Bankoo → Buydair pivot.
When software moves money or runs exams, “mostly works” isn’t good enough. I plan for failed payments, dropped requests and edge cases before launch, not after.
Slow networks, power cuts, low-end phones. I design for the environment people actually use software in, like an exam system that runs with no internet at all.
I use AI tools to move faster, but nothing ships until I’ve read it, tested it and understood it. If it’s in production, I can explain every line.
Teaching developers every week has made me clear by habit: readable code, honest updates, and handovers your team can actually pick up.
Clear updates while I build, honest estimates, and documented handovers, so you always know where things stand and your team can pick the work up after me.

02 — ABOUT
aka devpeter
Olatunji Peter, known online as devpeter, is a full-stack and frontend engineer based in Ogbomoso, Nigeria, currently Full-Stack Engineer & Educator at JAARC. With 4+ years of building production web software and a B.Sc. in Computer Science, he builds products where reliability matters: payments, exams, and platforms people depend on every day.
He is the solo developer behind Buydair, a payments-first wallet for airtime, data, electricity and TV subscriptions, funded through Paystack with webhook verification, automatic recovery of stuck purchases and audited refunds, and paired with free courses that teach people to recognise scams.
At JAARC he built an offline computer-based testing system used by more than 1,000 students. He also built the website and admin platform for True Worshippers Church, where members stream and download sermons.
Alongside building, he teaches: mentoring 10+ students in HTML, CSS & JavaScript, React, AI, digital literacy, from their first web page to shipping real projects. Explaining decisions every week keeps his own engineering clear and well reasoned.
