Building practical software from real-world experience

I’m a journeyman welder turned independent developer building software around problems I’ve actually encountered — not problems invented for a pitch deck.

My work currently focuses on two areas:

🔧 Practical tools for the trades

Pipe Layout Pro is an Android app built for welders, pipefitters, fabricators, apprentices, and other tradespeople who need fast, accurate pipe layout calculations in the field.

It includes tools for trunnion layouts, 45° and 90° branches, miter cuts, saddles, saved calculations, metric/imperial measurements, and offline use.

Pipe Layout Pro is now live on Google Play, and I’m continuing to improve it based on real-world feedback from the people actually doing the work.

💪 Technology for recovery and personal change

I’m also building software focused on recovery, accountability, habit building, and helping people make meaningful changes without turning every useful feature into another subscription.

Privacy, accessibility, and practical usefulness matter more to me than adding features just because they look good on a product page.

❤️ What sponsorship supports

I’m an independent developer, so GitHub Sponsors directly helps cover:

Development and testing
Android devices and testing costs
Google Play publishing and maintenance
Hosting and API expenses
Bug fixes and ongoing support
New calculators and features
Documentation and accessibility improvements

You’re not funding a giant software company.

You’re helping one guy keep building tools that might actually be useful to somebody.

If one of my projects saves you time, solves a problem, or simply seems worth keeping alive, I’d appreciate your support.

Thanks for helping me keep building.

@thatappguy71

The first milestone isn’t some ridiculous venture-capital number. It’s ten people saying: “This is useful. Keep going.” Reaching 10 monthly sponsors will help cover ongoing development, testing, publishing, and maintenance while Pipe Layout Pro grows and TrueTether moves toward release. Every sponsor helps keep independent development moving.
