Hi! This is something we can definitely take on. Before committing to a scope or price, a couple of things I'd want to understand first. The "85–90% complete" framing can mean very different things depending on the codebase state — have you got a repo we can review before we lock in anything? A short technical audit upfront is the only honest way to give you a real estimate, since fixing someone else's native media pipeline and rendering bugs without seeing the code first is a bit of a blind bet for both sides. Also: is there any existing documentation or technical context from the previous engineer — architecture notes, known issues list, anything? That'd cut audit time significantly. On the stack, this fits squarely in what we do — React Native, Expo, TypeScript, Node.js, Cloudinary, native iOS/Android media handling. The areas you flagged (HEIC/iCloud import, camera recording, narration, memory crashes, render pipeline) are solvable, but the sequencing and effort depend entirely on what's actually in the code. Happy to start with the audit, map out the issues, and give you a proper breakdown from there rather than guessing at a fixed number now. Gustavo & the DoTheCode team

Hi, You're at a stage where a mature React Native/Expo app with media, camera, and creator tools needs stability and a production polish before launch. The operational realities, native module quirks, memory pressure, and cross-platform quirks, require careful audit and targeted fixes. I've steered production RN apps through audits, bug triage, and release readiness for video, camera, and media pipelines. I'll start with a focused audit of the media, camera, and story pipelines, isolate flaky paths, then apply stabilising fixes and regression checks. I'll validate on real devices, tighten memory usage, and prepare a repeatable build and test flow for submission. iOS media import and HEIC handling can surface tricky edge cases in bridging native modules. What should happen if assets disappear and reappear later during a session? What are your target release metrics and test coverage for iOS and Android before submission? If we're aligned, I'd be happy to walk you through the implementation plan before we get started. Best regards, Brandon

Hi there, Based on my understanding, I can see that you are looking for a senior React Native/Expo engineer to take over an already well-developed AI creator app, perform a technical audit, resolve critical stability and media-related issues, optimize performance, and prepare it for a successful App Store and Google Play launch. My approach would be to first conduct a detailed audit of the existing codebase, identify the root causes of crashes, memory leaks, and media issues, then systematically stabilize the camera, recording, rendering, and Story Builder workflows before optimizing performance, polishing the user experience, and preparing production-ready builds for both iOS and Android. Before we proceed, I just have a couple of quick questions: Which Expo SDK and React Native versions is the project currently using? Is the backend and Cloudinary infrastructure already production-ready, or are there outstanding backend tasks as well? There are also a few recommendations I'd like to share regarding the audit process, native iOS media handling, memory optimization, and launch readiness. Unfortunately, Freelancer.com's character limit doesn't allow me to include everything here, so please open a chat, and I'd be happy to discuss your project in more detail.

Your React Native app is close enough that the remaining bugs matter more than new features. Taking over an 85–90% complete codebase starts with understanding why the same issues keep resurfacing, not patching them one by one. I'd begin with the technical audit you described, trace the unstable paths, then focus on the launch blockers: native iOS media import, camera and AV reliability, memory usage, and the rendering flow. With Expo, problems around HEIC, iCloud assets, and FileSystem handling often need careful native debugging rather than changes in the JS layer alone. The goal is a stable release, not another round of temporary fixes. I'd keep each change measurable, verify it on both platforms, and avoid introducing regressions while improving performance and navigation. Which of the current launch blockers is still preventing internal testing the most: media import, rendering, or the Studio crashes?

I’ve handled React Native apps with complex media workflows, including camera features and video editing, so I understand the challenges you’re facing. The native iOS media import issue and camera recording bugs sound like they stem from deep integration quirks, which I’ve resolved before by auditing native module usage and memory handlers. My first step would be a thorough technical review to pinpoint instability and crashes, especially around Story Builder and the rendering pipeline. For example, I once improved video processing in a Creator Studio app by optimizing async tasks and media caching, which cut crashes and sped up export times. For a smoother Finish Video workflow, I’d suggest simplifying the user flow by batching render tasks and pushing processing to background threads to avoid UI freezes. Also, fixing iCloud asset imports often involves adjusting asset permission and format handling—can you clarify if HEIC and iCloud assets fail consistently in all contexts or only certain devices? I’m ready to jump in and stabilize SnapBumz fast, so it meets App Store and Play Store requirements and offers users a polished, bug-free creator experience.
