RomeoApps Written fit check

RomeoApps / build-to-proof studio

Buy one proof-bearing slice before you buy a software build.

I take one written symptom and return a bounded decision, a working vertical slice, or an agentic workflow with tests and evidence. The first milestone is small on purpose: it makes the next decision safer.

No generic “AI developer” pitch. The buyer can inspect what was checked, what remains unknown, and what the next paid milestone buys.

Uncertainty is the expensive part.

Make the first decision inspectable.

Three routes to a useful first payment

Choose the seam where a small proof can unlock a larger build.

These are not open-ended consulting packages. Each starts with fit, freezes one outcome, and leaves a trace the next engineer can run.

01

Agent workflow reliability

Make an agent useful without making it ungovernable.

Tool permissions, sandbox boundaries, traces, evaluations, recovery paths and an operator-readable handoff for teams moving from a demo to a dependable workflow.

02

Native and cross-platform reliability

Turn a fragile mobile path into a measured working surface.

Kotlin, Jetpack Compose, Media3, Paging, Flutter and browser/integration repairs with a focused test harness and a device- or emulator-backed receipt.

03

Payment and operations control planes

Replace a revenue leak or admin bottleneck with a visible control path.

Stripe flows, receivables evidence, membership rules, reporting and integrations: model the state transitions, expose the exception path, and prove one safe handoff.

Owned capability proof

The work is shown, not asserted.

The public artefacts below are RomeoApps-owned labs. They demonstrate the delivery mechanism without pretending to be customer results.

The contract is the advantage

A four-step path from symptom to shipped evidence.

  1. 01

    Fit

    Send a safe public or redacted target. I answer in writing whether the requested result is feasible and what evidence is missing.

  2. 02

    Freeze

    Agree one workflow, one acceptance test, safe inputs and the exact handoff before implementation begins.

  3. 03

    Build and verify

    I implement the smallest useful surface, run focused tests and capture evidence tied to the delivered source.

  4. 04

    Extend

    Only an accepted first unit earns a larger milestone or a reliability retainer. No scope leap based on a sales call.

Start with the problem you can name

One written symptom is enough to begin.

Do not send passwords, secret keys, private customer records or unrestricted access. A public URL, redacted log, fixture or short screen recording is enough for a fit decision.
