We're a pre-launch sports event app (Flutter mobile app + Django REST backend) preparing for App Store and Google Play submission. We need to migrate our subscription billing from Stripe to native in-app purchases (Apple StoreKit + Google Play Billing) before we can ship. The work is well-scoped: monthly + annual subscriptions, 7-day free trial, one subscription tier. No legacy users to migrate (no current Stripe subscribers). We have a written strategy document covering subscription lifecycle, edge cases (grace periods, refunds, restores), and store-side configuration — shared with shortlisted candidates.

Subject: Invite: Rapid Fixed-Price $500 App Stabilization & Integration Sprint Hello, I am looking to immediately onboard a top-tier domestic engineer to clear our workstation runway for a rapid, fixed-price $500 Framework Stabilization Sprint to drive our core multimedia application straight to a live grand launch. Our application architecture is pre-coded and fully intact on our master branch. Your terminal will focus strictly on targeted backend surgery and API integration to clear legacy regressions: The Sprint Scope Matrix: 1. Media State Management: Patch our 6-zone media player buffers where tracks cut out after 2 seconds. Cleanly un-brick the hardware microphone recording paths inside the vocal booth loop to stabilize audio-video lip-sync processing. 2. Gateway Sync: Synchronize our RevenueCat transaction product ID configuration strings so they match our live app store profiles. 3. Soundraw API Integration: Activate and validate our pre-built Soundraw API backend channels to stream multi-genre backing tracks over the air networks. This is a high-velocity, pay-for-performance sprint requiring a working build delivered to device glass on an accelerated holiday timeline. Let me know your immediate terminal availability so we can transfer our repository access tokens today.

We need someone who is an expert in Flutter, Firebase, Stripe, to create a Progressive Wed App from an app that has been approved for Android but not yet approved for IOS. The app has already been built, we need an expert to now create a web app version, add the link to the website, handle the Stripe integration for a subscription model. Once this is complete there is a chance to remain on the team to update the app as needed and handle updates. As the app was built in Flutter this should nto take long at all to convert to a web app.

Firstly, I want to state that I am not a coder. At all. The code I'd like you to review was entirely "vibe coded" using Antigravity and Claude. I don't intend to create a complete product using this method, in fact, I'd like to use real people as much as possible for my business. I used AI during this phase simply to see my ideas made material. I understand that this means the code itself is likely compromised in all sorts of ways, but I'm hoping that you can help me with that. Please speak with me as you would a fifth grader about the technical aspects of the code, assuming you'd like to work together from this point forward. My app is a free-to-user dating and date planning app that connects people through locally owned businesses. It serves two audiences: - **Singles** looking to meet and go on dates with other singles in their area - **Couples** looking for date night inspiration through a linked accounts mode

We are looking to do a new build of our patch bay label designer tool. Customers are currently able to pick their model of patch bay, add text labels, colorize, and group. They can then checkout and it creates print ready artwork for our team to produce. The UI is a bit clunky and there are some features we want to add such as an admin tool to add and edit labels.
