Full-Stack AI Developer · Cardiff & Birmingham, UK

Code with a human pulse, not a corporate script.

I'm Sarah — a full-stack developer who builds software the way I'd want to use it: clear, fast, and free of jargon. No "bespoke solutions tailored to your needs." Just tools that work, for people who actually need them.

The human bit

The world needs a human touch. That's what I bring to software.

I'm a full-stack developer obsessed with using code and logic to solve real problems for real people — not hypothetical ones in a slide deck. I handle everything from the front-facing experience to the architecture underneath, so the tools I build aren't just powerful, they're effortless to use.

While I've got a solid technical foundation in web systems and AI, I'll always choose real interactivity, clarity, and genuine connection over buzzwords. If a sentence needs a glossary, I haven't finished writing it yet.

Community Uplift

Built Cardiff Community Meals to connect local kitchens with vulnerable neighbours.

Small Business Uplift

Free website audits and Project OS — built for entrepreneurs, not enterprises.

Hackathon Energy

Thrives under deadline pressure — lifts teammates, unblocks code, keeps momentum.

Zero Jargon Policy

If it can't be explained plainly, it doesn't ship until it can.

What I bring

Full-stack chops, human-first instincts.

Three things I take seriously on every build: the code underneath, the person using it, and the team around me.

Dragon Fire Design

"Three seconds is all you get. I build the website that argues back."

Everything on this page — the no-jargon rule, the human-first builds — comes from the same studio I run under Dragon Fire Design: hand-built, accessible websites for tradeswomen and women in business who keep getting pre-judged. Free Doubt Audit on every enquiry; you own the site outright, no monthly rent.

The SJH Process (Project OS)

A twelve-phase project delivery system built on a simple belief: nobody should have to type "any update?" 69 guided tasks, 72 templates, live client sign-in — licensed to other studios for a one-time £39, not another subscription nobody asked for.

Community

Cardiff Community Meals

Lead developer and designer on a bilingual (Welsh/English) platform connecting vulnerable neighbours with meals, donors, and local Cardiff kitchens. Built for every age group and every level of technical confidence — because the people who need it most shouldn't need a manual.

Bootcamp Team Project

Mission Control

Co-built a Pomodoro focus timer with a four-developer Agile team under a hard bootcamp deadline. My job wasn't just writing code — it was keeping the team's momentum high and unblocking whoever was stuck, whenever they got stuck.

CarbMate

A carb-counting and insulin bolus calculator, built because I'm a type 1 diabetic who found every existing app either too fiddly or paywalled. Free to use, built to learn from as you go.
