Taking on new projects
I build the systems your business runs on.
I'm Johnson, a senior backend engineer. For six years I've built payments, banking and e-commerce platforms that handle real money, and I'll build yours to the same standard.

About me
I've spent six years building the systems behind money: bank accounts, wallets, cards, payroll and payments. I've done it for a live digital bank, a payment service bank, a core banking platform used by hundreds of institutions, and SaaS products that whole companies run on.
That's the standard I bring to client work, whether it's an online store that has to take payments safely on sale day or a fintech product that has to pass a security audit before launch.
I started out in IT support, which taught me that the job isn't done until the person using it is happy. So I explain things in plain language, show progress early and document everything. I'm based in Lagos and work with clients anywhere.

Common questions
Something else? Ask me on WhatsApp.
How much will my project cost?
Every project gets a fixed quote after a short scope call, broken into milestones. You see the full price before any work starts, and you pay as milestones are delivered, not all upfront.
How long does it take?
It depends on scope. After our call you get a written timeline with dated milestones, plus regular demo links so you can see it taking shape.
Can you build the whole website, not just the backend?
Yes. I deliver complete web applications end to end. My specialty is the hard part underneath: payments, security, data and integrations that have to work every time.
Can you take over or fix an existing product?
Yes. I start with an audit of the code and production logs, tell you plainly what's wrong, then fix it in priority order.
Which payment providers can you integrate?
I've integrated NIP inter-bank transfers, CoralPay, GTBank GAPS bulk payments and core banking systems. For online stores I set up whichever gateway fits your market, such as Paystack, Flutterwave or Stripe.
Will you sign an NDA? Who owns the code?
Yes, I'm happy to sign an NDA, and much of my work is confidential. You own the code and everything built for you once the project is paid in full.
Do you work with clients outside Nigeria?
Yes. I work remotely from Lagos (WAT, UTC+1), which overlaps fully with UK and European working hours and partly with the US.
What happens after launch?
You get documentation and a proper handover, plus a support window after delivery for fixes. Ongoing maintenance and new features can be agreed separately.
Tell me what you're building.
Send a quick brief and I'll reply within a day. If it's not a fit, I'll tell you that too.
