Descrição da demanda

We are looking for a highly qualified Mid-Level or Senior Developer to perform a comprehensive technical audit, stabilization, and controlled bug fixing on our platform, infinitifood. This is a SaaS platform dedicated to restaurants, offering features such as delivery, pickup, dine-in service, QR code ordering, digital menus, a PWA, and native apps for both Android and iOS.

It is crucial to understand that this is not a project to "rewrite everything." Our goal is to find a responsible professional who can understand legacy code, accurately diagnose bottlenecks, safely implement fixes, perform rigorous testing, and document every step of the process.

Initial Project Scope:

1. Detailed analysis of the technical architecture of the PWA and the Android/iOS applications.
2. Identification of the main risks and existing technical issues within the platform.
3. Creation of an objective report detailing the root cause, impact, priority level, and a remediation plan for the identified issues.
4. Fixing one small-to-medium complexity bug (to be agreed upon before starting the work).
5. Delivering fixes via Git (branch/pull request) or through a traceable package.
6. Providing clear testing evidence, such as screenshots, logs, builds, or a validatable step-by-step test plan.
7. Providing guidance on next steps and technical recommendations for the future evolution of the project.

Desired Technical Skills:

- PWA (Progressive Web Apps)
- JavaScript, HTML5, and CSS3
-PHP (with specific experience in CodeIgniter or legacy PHP structures)
- MySQL
- REST APIs
- Ionic / Cordova / Capacitor
- Android Development (including Gradle, current Target SDK requirements, and Google Play publishing)
- iOS Development (including App Store publishing)
-Service Workers and caching strategies
- Git (version control)
- Debugging and log analysis

Important Note on Security: Access to the environment will be strictly controlled. Initially, we will not provide keys, keystores, Apple certificates, production credentials, tokens, or direct access to the live production database. All work must be conducted in a dedicated staging/homologation branch.

We do not accept temporary workarounds, undocumented code changes, deliveries without adequate testing, direct modifications to the production environment, or promises of a complete system rewrite without a prior diagnosis.

Screening Questions (Please answer in your proposal):
1. What is your experience with PWAs and hybrid mobile applications?
2. Do you have hands-on experience with Android, Ionic, Cordova, and Capacitor?
3. Have you successfully published and updated apps on Google Play and/or the Apple App Store?
4. Have you taken over and managed legacy codebases before?
5. How do you validate and test a bug fix before delivering it?
6. Are you comfortable working strictly with Git, branches, and Pull Requests?
7. What would be your technical approach for the first 7 days on this project?
8. What is your fixed-price quote for the initial diagnosis report + the first bug fix?
9. What is your weekly availability (hours per week) for this project?
10. Can you provide examples or describe equivalent experiences from your portfolio?

We prefer a fixed-price arrangement for this initial phase, with a strong possibility of ongoing, recurring work after successful delivery and validation.
