Independent solo software builder · 23rd Ave LLC

I build the app you envisioned — or you don't pay. Period.

And that's not just a bold statement. It's how I build — from the very first day, every decision aimed at the impact you're after and at wowing you at the same time. I use AI to build apps, but I don't use AI in my apps. I build the real, finished thing.

The short version

A full product normally means an agency, a team, six figures, and a year. I deliver that alone — I direct a stack of AI models chosen for their strengths, one doing the heavy lifting, so one person moves at studio speed and actually finishes. All the way to a store listing. More than once.

The proof — three products, built solo

PrecisionEdge

iOS · Augmented Reality App Store approved
Point at your target and tap — and watch your shot's trajectory draw itself onto the real course in front of you, with GPS shot-tracking and dispersion analysis. Localized in four languages. ~19,000 lines of Swift.
ARKit world-trackinggeospatial / GPS Vision / CoreMLtrajectory physics

A privacy-first safety app

Android + iOS · Security App Store approved
Genuinely hard tech: an AES / KeyStore encrypted vault behind a PIN, user-trained spoken command words that fire silently with quiet confirmation, gaze detection (knowing when eyes are on you), Bluetooth scanning for unknown trackers, and a reliable background-service backbone. Shipped on two platforms — and the Android build is the more capable of the two. ~69,000 lines.

Multi-model orchestration

Method · How the above gets built
The engine behind it: one builder directing a stack of AI systems, one doing the heavy lifting, so the work stays tight and finishes. The products above are what that method makes when it's aimed at a hard problem.

How I work

You deal with the builder

No account manager, no offshore hand-off, no telephone game. You'll talk to one person — me — and I'm building it.

Studio output, solo overhead

What a team quotes at six figures, I can deliver for a fraction — the leverage is AI, not headcount.

I finish things

Most builders hand you a demo that almost works. I hand you something that passed review and runs in the field.

Very picky — and deliberate

I only take work I find fun and challenging, and what I build is serious tech — so I'm deliberate about what I take on and who it's for.

Where the ~$1M comes from

To be clear: it's not revenue and not a price tag. It's the cost to replicate — what a professional shop would invoice to rebuild these apps from scratch — measured feature by feature from the actual source code, at conventional US contract rates.

Ranges reflect normal estimation uncertainty. A measure of build effort, not market value.

Have something worth building?

Tell me the problem. If it's interesting and I have room, I'll tell you honestly what it takes to ship it — and if the finished app isn't what you pictured, there's no charge.
