Services · Prototypes & MVPs

Your fintech idea,
built to hold up
in the room.

I'm a banking product lead and certified business analyst (CBAP). I turn fintech and financial-services ideas into working prototypes that account for compliance from day one, so they hold up in front of investors, bank partners and regulators.

    A written scope, timeline and price. You approve it and pay 50% to start.

  3. 3

    Final payment, then the live link, the code and the documents are yours.


Case Studies

Things I've built

Personal finance · Live

SaryMoni

The problem
People climbing out of debt lose track of what they owe, what's left after essentials, and which debt to clear next.
What I built
A mobile-first, installable app (PWA) that shows the monthly surplus at a glance, orders debts smallest-first, tracks the emergency reserve, and logs job applications with a reader that pulls details from the posting link.

Screens shown with sample data. Live demo on request.

9jaStickas

The problem
Finding the right WhatsApp sticker means scrolling through hundreds. Nothing searches them the way you search GIFs, least of all for Nigerian slang.
What I'm building
A sticker organizer with search built around Nigerian expressions and local sticker culture.

Demo coming soon.

Merchant tools · In build

ReceiptFlow

The problem
Paper receipts get lost, and merchants lose the chance to stay in touch with their customers after a sale.
What I'm building
Digital receipts for merchants and their customers, with onboarding that starts at the first scan.

Demo coming soon.

Why Work With Me

A builder who has sat on the bank's side of the table

Seven years inside Nigerian banking, designing savings, lending and diaspora products and taking them through credit, risk and compliance sign-off. I know what a bank partner or regulator will ask before they ask it.

Regulatory fluency

Your prototype is shaped by the rules that will actually apply to it.

FAQ

Good questions to ask

How long will my project take?

Idea to Prototype takes 1–2 weeks, an Investor-Ready MVP 3–5 weeks, and Product Strategy + Prototype 4–6 weeks. The brief fixes your timeline before any work starts, and the clock starts once the deposit is in.

How many revisions do I get?

Feedback rounds are built into the weekly check-ins, and the brief sets how many there are. Changes that stay inside the agreed scope are included. Anything new gets quoted separately before I build it.

Who owns the work?

You do. Full ownership of the code, designs and documents transfers to you on final payment.

Will you keep my idea confidential?

Yes. I treat every idea as confidential and I'm happy to sign your NDA before the discovery call. I never show client work publicly without written permission.

How does payment work?

50% upfront to start, and the balance at handover. Prices are in US dollars; Nigerian clients are quoted in naira.
