Businesses I've built for and worked with

About

I build software that businesses run on.

I'm a full stack developer in Nairobi. For more than six years I've designed and built websites, business systems and mobile apps for companies in logistics, property, retail, employment and education, in Kenya and abroad.

I like work that people depend on every day: the till that has to keep selling when the internet drops, the rent ledger a landlord checks every morning, the operations system a whole team logs into. That means starting with how your business actually runs, then building something that fits it.

I scope carefully, show progress early and often, and stay reachable after launch. If something breaks, you message me, not a ticket queue.

What I do

Software for the way your business works.

From a first website to the system your whole team runs on.

    Fast, clear websites that explain what you do and make it easy for the right people to get in touch.

    • Business websites

    Cloud platforms and back-office tools your team logs into every day.

    • Cloud platforms

  • AI Automation, Data & Chatbots

    Less copy-pasting, fewer errors: automations, chatbots and data that answer real questions.

    • Workflow automation
    • Databases and dashboards

  • Technical Consulting & IoT

    A second opinion before you build, support once you have, and hardware prototypes when software is not enough.

    • Platform support
    • Arduino and IoT prototypes

Every project is priced on scope. After a discovery call, I prepare a project scope, SRS and project document, then a detailed quotation, so you know exactly what you're getting before any work begins.

  • Built around your work

    Software shaped to your process, not the other way round.

  • Offline-first thinking

    Systems that keep working when the internet does not.

  • Support you can reach

    A real person on WhatsApp or the phone after launch.

  • Built for Kenyan businesses

    SMEs, retailers, landlords and startups, with M-Pesa where it matters.

Process

My process is simple.

  1. 1

    Discover

    A free discovery call to understand your business, goals and constraints. I then prepare a project scope, SRS and project document, and a quotation.

  2. 2

    Build

    Iterative delivery with regular demos and feedback, so there are no surprises.

  3. 3

    Launch & Support

    Testing, deployment, training and ongoing support you can actually reach.

Clients

In their words.

  • Dennis built us a site that works the way we sell. Customers fill a cart and it reaches us on WhatsApp as a proper itemised order, and my team can update products and photos ourselves without calling a developer.

    Billy K., Owner, Bilvista Hardware

  • Dennis turned ExpertBridge from an idea into a working platform. He was clear about scope from the start, delivered in stages we could review, and was easy to reach whenever we needed a change.

    Felix G., Founder, ExpertBridge

  • Our clients are in the US, UK and Europe, and the site Dennis built explains what we do for them clearly and professionally. He kept us informed at every step and the whole process was straightforward.

    E. Mugo, Founder, Academianomads

  • Dennis built the RAJI Global website, our operations system and the GraceWorks platform from the ground up. Our teams use them every day, and he is the one who keeps them running and improves them as we grow.
