JOB OVERVIEW

I’m Hans Horlings, founder of SHIFT with Hans.
SHIFT is a live voice-first AI leadership coaching platform (currently a web app). I need one capable developer to rebuild it as a native mobile app for the Apple App Store and Google Play Store.

What you will build:

Core user journeys:
onboarding, 5 Professional coaching steps, Captain’s Card, daily/weekly/monthly check-ins, and “Ask Hans”
Full migration of voice conversations to Grok Voice Agent
All insight-generation prompts moved to Grok’s LLM API
Push notifications, background voice handling, and in-app subscriptions (StoreKit + Google Play Billing)
Keep the existing Supabase backend
Development in Cursor

You will work from a clear scope document. Existing product logic (grounding rules, privacy controls, progressive reveal) must be preserved — no redesign without discussion.

Requirements
Strong React Native experience (Flutter also considered if you can explain why)
Proven mobile app shipped to App Store and/or Play Store
Comfortable integrating voice agents and LLM APIs
Experience with Supabase (or similar Postgres + auth)
Clear English communication
Able to work independently and send weekly progress updates
Willing to sign NDA before any code or data access

Important notes
You will receive a current software and database copy, access to the working webapp used as MVP to test design and user interaction - now it is time to make it a phone app, more efficient and allow pop-up notifications and reminders.

Code ownership transfers fully to me on completion.
Timeline target: solid, usable v1 that can be improved continuously (realistic developer estimate after discovery is expected).

How to apply:

Reply with:
Short intro + relevant experience
Links to 1–2 apps you have published (App Store / Play Store)
Your preferred rate (hourly or fixed per milestone)
Availability start date

Looking for one focused, reliable developer who wants to ship something meaningful and iterate from real users.

After initial project we expect this person to become a valuable asset in the organization and improve product functionality over time, especially with new AI capability, and better user demand insights.

Onwards & upwards ???? — Hans
