Need an online shop?, a mobile app?, a marketplace?, M-Pesa payments?, an AI assistant?, more Google traffic?
I'm Wanjiku. I build online shops, mobile apps, marketplaces and business systems for Kenyan companies, with M-Pesa wired in and Google in mind from day one. Five of them are live right now. Open any one and judge for yourself.

What I do
Pick one, or combine them. Each is a job I do myself.
Everything I take onFast, clear sites that tell people what you do and make it easy to buy or get in touch. Built for phones first, because that is where your customers are.
Android and iOS apps for your customers or your team, built with React Native. One build for both phones, sharing accounts and data with your website.
Custom platforms with accounts, listings, bookings, dashboards and admin tools. The kind of thing a spreadsheet and three WhatsApp groups can no longer hold together.
STK Push, payouts, callbacks and reconciliation, tested properly. Cards and Airtel Money too, so nobody walks away at checkout.
A chat assistant that answers customer questions in English and Kiswahili, then hands the serious ones to you with a phone number attached. Try the one on this page.
Clean structure, quick pages and the right markup, so Google can read your site and visitors do not wait for it. I also take over sites that were left half-finished.
Why me
You do not have to take my word for it. Check the work, ask the assistant, then decide.

Quickest way to start
No long forms. Your name, your number and what you need. I reply within one business day, usually sooner.
How it works
Not the feature list. What should this bring in? Orders, bookings, enquiries, fewer phone calls? A short chat or a WhatsApp message is enough.
What I will build, what it costs and when you will see it. No surprises halfway through.
You see real progress as it happens, not a big reveal at the end. Then we launch, and I stay around to fix and improve.
About
Who takes the orders? Who chases payments? Where do things get lost? I want those answers first, because that is what the software has to fit.
I work for myself. No agency, no company and no boss sits behind me, so every decision on your project is mine and every message you send is read by me. I build with the tools Kenyan businesses actually run on: M-Pesa, WhatsApp and the phone in your pocket. When you hire me, you deal with me, not a salesperson and not a project manager.
That includes mobile applications. I build Android and iOS apps with React Native, the same way the RentBoxGo app sits alongside its website. Your customers get a proper app on their phone, and it shares accounts and data with everything else I build for you.
Questions
Something not here? Ask the assistant. It answers in seconds.
Because you can check before you ever message me. Five of my products are live, so you can open them, use them on your phone and see how they behave. You deal with one person who builds the site, the app, the payments and the search setup, and I answer to nobody but my clients.
It depends on what it needs to do. A simple business site and a marketplace with M-Pesa payments are very different jobs. Send me a short brief and you will get a clear quote, not a vague range.
Yes. I build Android and iOS apps with React Native, and they can share accounts and data with your website. RentBoxGo has an app alongside its site. Sometimes a fast mobile site is the better first step, and I will tell you honestly which one you need.
Yes. I have built assistants that answer in English and Kiswahili, like Soko AI on Agrisoko and the AI tutor on Kenyaplex. You can try the one on this page by clicking Ask Wanjiku AI.
Yes. Broken forms, slow pages, payments that fail, a developer who stopped replying. I will look at what is there, tell you honestly whether to fix it or rebuild it, and go from there.
Yes. I have built STK Push payments and B2C payouts into live products, including handling the callbacks properly so payments and your records agree.
I build for search from day one: fast pages, clean structure, proper titles and markup. Rankings take time and nobody honest can promise page one, but a well-built site gives you the best possible start.
I call or WhatsApp the number you left, usually within one business day. I ask a couple of questions, then send you a plan and a quote. You decide from there.
Yes. Most of my work happens over WhatsApp, calls and shared screens, with clients in Nairobi and elsewhere in Kenya and abroad.
