Personal workshop & tool library

I build things that make life a little easier.

Some are useful. Some are experiments. A few might actually be brilliant.

Welcome to my little corner of the internet where ideas turn into calculators, tools, apps, and the occasional happy accident.

The Workshop

Fresh from the workbench.

Here's where the projects live. Some are ready to use, some are still evolving, and others are waiting for me to figure out what they want to be when they grow up.

Coming Soon

Calculators

Calculators

Quick math for decisions that matter — loans, ROI, savings, and the occasional what-if.

Coming Soon

Everyday Tools

Everyday Tools

Small utilities for the repetitive stuff — time, text, units, and the things you do ten times a day.

Testing

Experiments

Experiments

Half-formed ideas in public. Mostly for curiosity, sometimes surprisingly useful.

Coming Soon

On the Bench

Coming Soon

Things on the workbench that aren't quite ready to leave the bench yet.

Why this exists

I keep running into problems. So I build things.

I build tools to solve problems I keep running into.

Some start as quick experiments. Some turn into systems I use every day. A few might become real products.

Most of them just help me think better, move faster, and stay out of my own way.

You're welcome to explore, use, or break anything you find here.

Have an idea?

Got a problem worth solving?

I'm always curious about the little frustrations people deal with every day. Sometimes a spreadsheet, calculator, or tiny app can make a surprisingly big difference.

Have an idea? I'd love to hear it.

No pitch decks. Just the problem.
