Design Systems
Intro
I’m a product designer who partners with teams to turn ideas into real products. I focus on clear interfaces, sharp decisions, and systems that last.
From research and wireframes to high-fidelity prototypes and design systems in Figma, I take products from first sketch to shipped screens — and I write the front-end code too.

IST Legal
IST Legal is an AI legal intelligence platform grounded in Rwandan and Kenyan law. The brief was blunt: the site felt “more SaaS than legal.” I redesigned the full multi-page website so a lawyer understands in seconds that this is a purpose-built legal product, not a generic AI assistant with legal copy. Every demo shows believable legal work with verifiable citations, and the whole site runs on one design system.

Script
Script turns an organisation’s documents, scans, meetings and work tools into answers with sources, matched to what each person is cleared to see. I co-founded it and designed the product, the brand and the site: cited answers as the interface, clearance before the AI sees anything, and workflows written in plain Markdown.

Engineering
I build what I design. Front-end work in React, Next.js and React Native so the shipped product matches the file.
