Description
Experience Level: Expert
You are likely European or American to do this job. The requirement is normal, but endless lies and false promise has now made me take a substantial step I am looking to hire an expert for this task, not an amateur. The requirements are straightforward but must be executed with precision and professionalism. I expect proper error handling, thorough code commenting, and the ability to work independently without constant guidance.
To be considered for this role, you must meet the following criteria:
1. Experience working on a Mac M1/M2, including compiling code on this platform.
2. A proven ability to handle and obtain necessary certificates.
3. Previous experience in developing and delivering high-quality code with proper testing and debugging.
Please note: I am hiring an expert who can deliver results without false promises or unnecessary delays. If you meet the criteria and can deliver top-quality work, I look forward to hearing from you.
Overview
We are urgently hiring an expert Flutter developer to reconnect existing API workflows, resolve minor GUI issues, and ensure proper handling of native libraries and pods for both iOS and Android. The project is straightforward as existing production code from the master branch already contains correct API calls. The remaining work involves reconnecting workflows, minor debugging, testing, and ensuring all native dependencies (libraries and pods) are properly configured.
Scope of Work with Hourly Estimates
- Reconnect API Workflows: Reconnect `_sendDataToApis` to send data to API 127 & 98 in `file_over_provider.dart` – 1–2 hours.
- Fix Selfie and Colour Data Workflow: Adjust and reconnect `sendColoursAndSelfieToAPI98` using existing code – 1–2 hours.
- Update Login Workflow: Add API trigger after login in `login_screen.dart` – 0.5–1 hour.
- Fix Visualisation Crashes: Debug and adjust rendering logic in `selfie_view_area.dart` – 2–3 hours.
- Reconnect Questionnaire API: Reuse and reconnect `submitQuestionnaire` and `fetchQuestionnaireData` in `questionnaire_api.dart` – 1–2 hours.
- Resolve GUI Issues: Fix menu overlays, camera issues, and ensure seamless navigation – 3–4 hours.
- Ensure Native Libraries and Pods Are Properly Configured: Verify and fix any issues with iOS pods and Android native libraries – 1–2 hours.
Testing
- Conduct end-to-end testing on both iOS and Android platforms, including verifying native libraries and pods – 2–3 hours.
Requirements
- Must have prior experience deploying and debugging Flutter apps for both iOS and Android.
- Existing production code works correctly for most workflows except API triggers after login. You will primarily focus on reconnecting and reusing existing logic.
- Must verify and ensure native libraries and pods are properly configured for iOS and Android builds.
- Own an M1/M2 Mac and be fully capable of handling iOS-specific builds, including pod installation and troubleshooting.
- Strong expertise in Flutter, API workflows, GUI debugging, and handling native dependencies.
- Ability to work independently with minimal supervision.
Important Notes
- Existing production code from the master branch is correct and working for API calls and workflows. You are expected to reuse this code and ensure proper integration during login.
- The last developer lacked iOS knowledge, which caused delays. You must be highly skilled in iOS development, including handling pods and native libraries.
- This is a high-priority role with immediate start.
We look forward to hearing from you!
ALSO: I should not need to specify every millimeter of the job. Some things are given, Its like you need to eat when you are hungry, do I then need to tell you to get food and cook it? If you are a developer you know how things work.
LASTLY: do never ever tell me the code is bad and it takes many many days. I know this argumentation and its nothing you get from me. You get a detailed specification on file level what code is wrong and how it should change.
NB: Do not ask for calls. I am not interested simply.
