I build and ship production software on my own — design, engineering, release and support. 20 apps are live right now across the web, macOS and iOS; 10 of them went through Apple review. Every one is free, everywhere, with nothing to buy.

All free, no paid tier anywhere. One product ships on both the web and the Mac, so the three columns count 21 entries for 20 apps. Every link goes to the live product, not a screenshot.

Four worth opening

Picked for range rather than rank — a study platform, a hazard system, a native Mac app, and one built around a hard privacy constraint.

MSRX Planner

Students juggle a planner, a notes app, a flashcard app and a reminders list that never agree with each other.

Offline-first. Writes queue locally and reconcile on reconnect, so the planner keeps working with no network.

MSRX WeatherWatch

Weather apps report conditions but not risk, and hazard warnings live on separate government portals.

Fifteen independent hazard engines behind one API, with a provider abstraction so the model layer can be swapped.

MSRX Canvas AI

Annotating a screenshot of something confidential should not involve a round trip to someone's server.

On-device inference through Apple's frameworks. Nothing is uploaded and no API key is needed.

IncognitoCV

Resume tools ask you to upload the most sensitive document you own to a server you do not control.

No accounts and no server-side storage. The key stays in the browser and the document never leaves it.

How I work

End to end, alone
Each of these went from an empty repository to a live URL or an approved App Store listing without a team to hand it off to. Design, build, ship, then support it.
Three runtimes, one standard
Swift and SwiftUI on Apple platforms, TypeScript and React on the web. Different tools, same expectations for correctness, accessibility and speed.
Free, and not the trial kind
All 20 are free everywhere, with no paid tier, no subscription and no upsell. 19 of them do not even ask for an account — open one in a private window and it works.
Privacy as a constraint
Several process entirely on the device — no account, no upload, no server-side copy. It is harder to build that way and it is the right default.

Building something, or hiring someone to?

Email is the fastest route and it reaches me directly. Tell me what you are trying to build and where it is stuck — that is a more useful first message than a request for a call.
