Hi, I'm Betty

● Full-stack developer · Nairobi · Available remotely

I build what a business runs on, and ship it.

I'm a full-stack developer. I build real software end to end and use AI to ship it in a fraction of the usual time, without cutting the parts that matter. I take messy, manual work and turn it into systems people actually use, whether that's a full platform, a website, or the automation around a business. My biggest build so far is a live, multi-tenant platform I took from spreadsheets all the way to production.

What I do

Services
Systems

Custom business software

From internal tools to full platforms. The complex, data-heavy things a business actually runs on, built to be correct.

Websites

Sites with a custom admin panel

Fast, clean websites, plus your own admin panel so you update the content yourself. Built properly, not dragged from a template.

Portfolios

Sites that make you look credible

Personal and portfolio sites for people who need to be taken seriously online. You're looking at one right now.

Workflows

Automation with AI

Automating the repetitive parts of a business so the boring work runs itself, and people get their time back.

Consultancy

From manual mess to a plan

Turning a tangled manual process into a clear plan for the software that should replace it. I've done the implementation side for years.

● Live in production Multi-tenant platform

A multi-tenant platform that runs an aviation fuel business end to end, from the delivery slip at the aircraft through invoicing, payments, approvals and reporting. A big, real system with a lot of moving parts, designed and built from an empty repo to live production.

TONEYGLAD

Website + admin panel Full-stack

Kitly

Digital products Solo

My own small product line for freelancers and virtual assistants: a pricing and rate calculator, and a Freelance Kit of trackers, sold as digital downloads. This is where I build for a market instead of a brief, and learn the whole product side, not just the code.

How I work

Approach

I spent five years implementing and supporting business software for other companies, so I've seen exactly what makes these systems work once real people depend on them day to day. Now I build them myself, with that hard-won experience baked in from the first line.

I'm a builder at heart, and I think in whole systems, not just features. AI is how I move at the speed of a small team; the architecture, the judgment and the hard calls stay mine. The tools make me faster, they don't make the decisions.

Give me the messy, exact problem.That's usually the one I want.

How we'd work together

Onboarding
  1. 01

    A quick chat

    You tell me what you're trying to do, whether it's a full build, a website, an automation, or just a decision you need a second opinion on. No jargon needed. We work out if I'm the right fit before anything else.

  2. 02

    Scope & a clear quote

    I write back what I understood, what I'd deliver, roughly how long it takes, and what it costs. Plain language, no surprises. You approve before any work starts.

  3. 03

    I build, you stay in the loop

    I work in small, visible steps and share progress as I go, so you're never waiting in the dark. You can course-correct early instead of at the end.

  4. 04

    Handover & support

    You get the finished thing, running, with what you need to use it. I don't disappear after delivery, if something needs a tweak, I'm reachable.
