Selected work

What this work shows

These are six products I designed and built. Each one has its own page with the problem, my approach, the stack and screens. I work as one engineer, end to end, so the same person who writes the plan also writes the code and runs the release.

The pages cover native apps, real-time systems, WordPress, a community platform, a shared sign-in and AI features. If you want the short version of what I offer, see the services overview.

How to read the screens

Every screen on these pages is either from a product I own or from a demo with sample data. I label them. "Demo with sample data" means a made-up town, made-up people and test accounts. No real residents, no real positions, no real users.

Where a product sits on a third-party base, the page says so. I do not claim results I cannot show: no download counts, traffic or rankings.
