Hey, I build small tools
that solve real problems.

I'm a solo indie maker. I find an annoying problem, ship a tool that fixes it, then move on to the next one. Most of them are free. A few make me coffee money. All of them are built by one person with way too many tabs open.

Stuff I've built.

12 products

Each one started as a problem I had — or a problem someone close to me had. None of these had a business plan. They just shipped.

Long-form writing

Notes from building 12 products solo — plus deep guides on the topics my tools cover.

About the studio

One person. 12 products. Zero VC.

Peak Apps Studio is one indie maker shipping software. Every product here started as a scratch-your-own-itch — a tool I needed, a problem someone close to me had, or a niche I noticed that nobody was serving properly.

The rule is simple: ship lean, no dark patterns, no friction tax on the user. If a product can't earn its place by being genuinely useful, it doesn't ship.
