Digital systems builder — Limbe, Cameroon
I'm Xavier Ninga. I rebuild sites that are quietly losing money, and I automate the manual work behind them — bookings, payments, invoices, follow-ups. Below: what I've rebuilt, what I've shipped, and what I'm building next.
The point of the work
Anyone can build a page. These are the numbers the systems moved.

Selected work
A fintech KYC portal, a luxury storefront with an on-device AI concierge, a full-stack AI SaaS platform, and a hospitality booking engine. Each case study explains the problem, the process, and what was built.
A paper-based credit-union membership process, moved fully online — with in-browser passport-photo verification, adaptive KYC uploads, digital signatures, and a complete staff admin dashboard.
A complete luxury e-commerce experience for watches and fine jewelry — a 33-page storefront, a full admin dashboard, and a rule-based AI shopping concierge that runs entirely in the browser. Zero runtime dependencies.
A self-initiated, SaaS-grade 'AI Business Hub' — a polished marketing site plus a reusable full-stack architecture for auth, AI chat, payments, CRM and a customer portal. 60 routes, prerendered.
A full-stack hospitality platform for a luxury apartment, office and events complex in Limbe — a five-step booking engine, a hospitality management dashboard, and a 13-page site.
Building next
Four systems currently in development. Each one has a full write-up in /plans — the problem, the build, and what it should change.
Restaurant · Coastal Grill & Kitchen
A fresh-catch seafood grill in Limbe. A menu that's actually pleasant on a phone, and a reservation that confirms itself on WhatsApp instead of ringing a busy line.
Tour operator · Mount Cameroon treks
Guided treks and coastal tours sold online — trip pages, live departure dates, deposit payments by Mobile Money, and guide scheduling behind the scenes.
Clinic · Appointments & intake
A clinic site where patients book a slot, fill intake before arriving, and get a reminder — so the waiting room stops being the booking system.
Real estate · Listings & viewings
Property listings with real search, a viewing scheduler that respects agent calendars, and a diaspora-friendly enquiry flow for buyers who can't walk the property.
The automation suite
A website is where your business lives. Automation is what makes it run. These five remove the repetitive work that eats your week — and they plug into a site you already have.
Bookings that confirm, remind and never get lost
A customer fills your form — then waits. Someone has to see it, reply, write it in a book, and remember to remind them. Every step is a place the booking dies. Most no-shows aren't rudeness; they're a missing reminder.
Match every MoMo payment to the right order — automatically
Payments land in MoMo and Orange Money. Orders live somewhere else. So someone sits with a phone in one hand and a list in the other, matching them by eye — every single day. It's slow, it's error-prone, and it's how money quietly goes missing.
Order in, invoice out, nobody types anything
An order comes in. Someone opens Word, types the same details again, exports a PDF, sends it on WhatsApp, then writes it in a book. The same information, keyed in four times — and the fourth copy is always the one that's wrong.
Never lose an enquiry to a slow reply again
Someone asks about your service at 9pm. You see it at noon the next day. They already booked your competitor. Most lost sales aren't lost on price — they're lost on silence.
Turn every happy customer into the next two
Your best customers would happily recommend you — but nobody ever asks them, because asking is awkward and easy to forget. So your reputation stays invisible and your growth stays paid.
About
I build the system, not just the site.
Based in Limbe, Cameroon, I work across two worlds: businesses here who live on WhatsApp and mobile money, and international clients who need the modern stack — Next.js, Supabase, Stripe, multilingual, deployed clean on Vercel.
The thread through every project is the same: take something a business does by hand, every day, and make the software do it instead. That's where the real value is — and it's what I care about most.
In their words
Xavier moved our whole membership process online without losing an ounce of the rigour we need as a credit union.
The platform finally matches the building — and it runs our bookings instead of us chasing them.
