The founder.
Sean Nkiwani
Founder & lead engineer
Sean is a developer who builds across the whole stack: brand and interface at one end, databases, auth, payments, AI services and deployment at the other. A voice-first chess tutor, a gourmet catering brand, a cafeteria ordering platform and a lead engine for the Los Angeles HVAC market are all his work. They share almost nothing except the standard applied to them.
He founded YellowCC after watching the same thing happen over and over: businesses with real customers and real reviews losing work to competitors who simply had a faster website and a booking form. The gap was never talent or price. It was engineering.
That is still the whole thesis. We build one kind of thing: websites engineered to turn search traffic into booked work. HVAC contractors in Los Angeles, restaurants in Cape Town, professional services in between. Different industries, one question every time: how does this page produce a phone call.
Sean leads a small team of specialists in design, content, and local SEO, brought onto a project when the work calls for them. Deliberately small, so the person who architected your build is still the person answering when you call.
Things we've built.
An agency brand, an AI product, a catering business, ordering software, and a lead engine. The range is the point.
School cafeteria ordering system
Full-stack
An ordering platform for a school cafeteria, structured like a proper e-commerce flow rather than a form: browse the menu, add to a cart, check out, and track the order through to collection.
How we work.
Four commitments that shape every project. They are the reason clients stay past the first build.
The founder is on every project
Not an account manager
Sean scopes, architects, and reviews every build personally. Nothing gets lost being relayed through a middle layer, and nothing gets promised that the team cannot ship.
Fixed scope, fixed price
Written before we start
Every project starts with a written scope and a number. No hourly billing, no change-order games, no invoice that lands 40% over the estimate.
Boring technology
Next.js, Tailwind, Vercel
We build on a stack that is fast, stable, and easy for any competent developer to pick up after us. You are never locked into something only we can maintain.
Measured, not guessed
Analytics from day one
Every build ships with tracking configured. We can tell you which page produced a phone call, not just how many people visited.
Let's see if we fit.
Fifteen minutes on a call. We will tell you honestly whether we can help, and if we cannot, who might.
