Launch plan
I take it from scope to the App Store: design, app, paywall, analytics, and the store submission itself. A TestFlight build is on your phone from day 8, not a status report.
New app, end to endCrashes, jank, a codebase nobody wants to touch. I audit it, fix the foundations, and leave you with releases that don't feel like gambling.

You talk to the engineer writing the code. I reply within a day.
On it. Build coming Friday.
Boring, battle-tested tools. Exciting apps.
Phase 01
You walk me through the idea or the codebase. I tell you honestly whether and how I can help.
Scoping call
Here's my idea. Is it buildable?
Yes. Here's how, and what it costs.
You walk me through the idea or the codebase. I tell you honestly whether and how I can help.
I turn your idea into screens and a locked feature list. You approve the scope and the fixed price before a line of code ships.
TestFlight builds land on your phone while it's being built. Real product, not Figma promises. You steer while it's cheap to steer.
Store assets, submission, review handling, release. You own the code, the accounts, and the docs.
Exact fixed quote after a short scope review, before any work or payment begins. No hourly billing.

I'm Ankit Kumar. Nine years building React Native products: senior engineering at MPL, a gaming platform with 90M+ registered users, four years of B2B fintech architecture at OpenEnvoy, and an AI consumer app on Google Play as frontend lead.
Then I proved the whole pitch on myself: Stretcho, my own posture app, went from empty repo to App Store approval in 8 weeks, built entirely solo. I work alone on purpose: no handoffs, no project-manager layer, no surprises.
Send me your app idea, or your existing app's App Store link, and I'll reply with a two-minute video of exactly what I'd build or fix. If it's useful, it's yours either way.
A 20-minute call, no pitch deck needed. If I'm not the right fit, I'll say so and point you somewhere better.
