Each one does a single job, in your browser, on your device. Nothing you open is ever uploaded anywhere.

Things I've built

Games, apps and business software. Some public, some built privately for one company and its exact headache.

Island Settlers

A Catan-inspired real-time 3D strategy game for mobile. Run an island, gather, trade, build, and race three AI settlers to thirteen points.

Sudokle

Sudoku, but the digits are letters and the answer is a word. A quick puzzle you can finish with your morning coffee.

Tressle

An AI-assisted study tool: turn what you're learning into questions, and practise until it sticks.

Daily Wins

A personal tracker for small daily wins — the habits and moments that add up. Built for me, kept private.

Simple automation tools

Small scripts and tools that take a repetitive office job off someone's plate: the retyped report, the monthly spreadsheet, the form that gets copied by hand.

Weather camera dashboard

A live dashboard of weather cameras and conditions, built as custom WordPress plugins for one site.

Why these are free, and what that tells you

Every tool here runs inside your browser. There is no server to pay for, so there is nothing to charge you for. They are the honest version of a portfolio: real software doing real work that you can try before you ever talk to me.

Built for the exact headache

Not a platform with 200 features you'll never touch. One thing your team actually does, made fast and obvious.

No accounts, no bloat

People shouldn't need a login to finish a five-minute job. The tools here prove it, and yours can work the same way.

Fast to ship, easy to keep

Small, plain, dependency-light software that keeps working after I've gone home. You own it outright.

Have a job that should be easier?

A form that gets retyped, a report rebuilt every month, a spreadsheet nobody trusts. Describe it in plain words and I'll reply by email.
