O Gymru i'r Byd — From Wales to the World

We build stuff
and plant seeds

/ar·LOY·see/ — Welsh for "innovation"

An experimental showcase exploring what happens when AI collaborates with a solo developer across multiple industry domains. These apps are built for learning and showcasing — not as commercial products.

Yr hyn rydym yn ei gredu

One developer. AI as a partner. Eight experiments.

Every app you see here was designed, built, and shipped by a single developer in Wales working alongside AI. They exist as experiments — to explore the boundaries of what AI-assisted development can achieve across completely different industry domains.

Ship fast, learn faster

We put real software in front of real users within weeks, not quarters. Feedback is our fuel.

🤖

AI is a teammate, not a buzzword

AI isn't just our tool — it's our collaborator. Every line of our code has been shaped by human-AI partnership.

🏳

Deep domain, not shallow demos

Each experiment dives deep into a different industry. The challenge is learning new domains fast, with AI bridging the knowledge gaps.

🤝

Users are friends, not tickets

We talk to our users like human beings. No jargon walls, no corporate speak, no hiding behind a helpdesk.

🏴‍☠️

Proudly Welsh, globally ambitious

We build from Wales with the audacity to serve the world. Cymru am byth.

🚀

Vertical integration wins

These apps don't just coexist — they share patterns, components, and lessons learned. Each experiment improves the next.

One person. AI-augmented.

The experiments. Eight domains.

Each app explores a different industry domain — built to test how far AI-assisted development can go. All data is from public sources; all content should be treated as experimental.

A fo ben, bid bont.

"He who would be a leader, let him be a bridge."

— Welsh proverb

Built with AI,
not just about AI

These experiments don't just use AI as a feature — AI is genuinely part of the development process. Every architecture decision, every algorithm, every user experience has been shaped through human-AI collaboration.

This isn't outsourcing thinking — it's augmenting it. A solo developer brings curiosity and a willingness to dive into unfamiliar domains. AI brings relentless capability and a fresh perspective. Together, they produce what would normally require a much larger team.

"One developer, one AI, countless experiments — exploring the future of software."
