We are looking to hire two dependable iOS Developers who value code quality, proper testing, and long-term collaboration. This is an ongoing maintenance and enhancement role for an existing application currently in the pre-production stage. We are not building a new application from scratch. We are looking for developers who can help maintain, improve, and evolve an existing product over time. ---------------------------------------- PROJECT STATUS ---------------------------------------- The project is already well established: • Existing iOS application • Existing PHP backend • MySQL database • Development, Staging, and Production environments • CI/CD pipeline with automatic deployment • Git-based development workflow ---------------------------------------- TECH STACK ---------------------------------------- • iOS Development (Primary) • PHP Backend (Yii2) — Basic familiarity is a plus • MySQL • Linux Server Environment • Git • CI/CD ---------------------------------------- RESPONSIBILITIES ---------------------------------------- • Handle weekly development and maintenance tasks. • Implement new features and business requirements. • Investigate and fix bugs. • Investigate API and backend integration issues when needed. • Occasionally make small backend (PHP) changes if required. • Maintain overall system stability and code quality. ---------------------------------------- WORK SCHEDULE ---------------------------------------- • Part-time, task-based collaboration. • Work is assigned in batches rather than fixed weekly hours. • Each batch of tasks will have an agreed delivery timeline based on its size and complexity. • Developers are expected to be available during five working days per week for communication, discussions, and task follow-up. • In rare cases, urgent production issues may require reasonable availability outside the normal schedule. ---------------------------------------- REQUIREMENTS ---------------------------------------- • Strong experience with iOS development. • Comfortable working with existing codebases. • Experience with Git branches and pull requests. • Able to investigate issues independently. • Good English communication skills for technical discussions. • Basic PHP/Yii2 knowledge is a plus. ---------------------------------------- WHAT WE EXPECT ---------------------------------------- • Investigate the root cause before implementing a fix whenever possible. • Deliver clean, maintainable, and well-structured code. • Every submitted task must be fully tested before delivery. • Testing should cover both the implemented feature and any related user flows to ensure existing functionality is not affected. • Large or risky changes should be discussed before implementation. • Communicate blockers early instead of waiting until the deadline. • Respect agreed timelines and take ownership of assigned tasks. • Quality is more important than simply closing tasks quickly. *** We expect consistent progress throughout each assignment. As a general expectation, at least one completed task should be delivered every 48 hours unless otherwise agreed based on the complexity of the assigned work. *** ---------------------------------------- PAYMENT & PERFORMANCE ---------------------------------------- • Payment is based on the agreed scope of each assigned batch of tasks. • Each task batch will have an agreed delivery deadline before work begins. Payment typically ranges from $50 USD to $300 USD per task batch, depending on the scope and complexity of the assigned work. • Payment will be processed after the assigned batch has been successfully validated and accepted. • If assigned tasks are not completed within the agreed timeline, payment may be adjusted based on the amount of unfinished work. ---------------------------------------- WHO WE'RE LOOKING FOR ---------------------------------------- We're looking for developers who take pride in their work, write maintainable code, and genuinely care about delivering stable, production-ready features. If you enjoy improving existing systems, solving real-world problems, and building long-term working relationships, we'd love to hear from you. ---------------------------------------- TO APPLY ---------------------------------------- Please include: • Your iOS experience. • Links to apps you have worked on (App Store or GitHub if available). • Your availability. • Whether you have any PHP/Yii2 experience.

A pre-production iOS app with an existing Yii2/PHP backend and MySQL, plus Dev/Staging/Prod and CI/CD already in place, is exactly the kind of setup I like stepping into — the work is about respecting what's there, not rewriting it. For batch-based tasks I'd start each one by reproducing the issue or spec against Staging, branch off Git, and keep changes tight and reviewable so your automatic deployment stays clean. On the iOS side I'd write feature work with unit/UI tests where it matters, and when a bug traces back to the API I'm comfortable dropping into the Yii2 controllers and MySQL queries to fix the root cause instead of patching around it in the app. I treat production incidents seriously and can be reachable across the five working days for follow-up and discussion. Since you flagged code quality and proper testing, one thing I want to scope early: does the existing iOS codebase already have a test suite you want extended, or would you like me to introduce testing coverage gradually as I touch each area? That changes how I estimate each batch. Happy to start with a small task so you can judge the quality before committing to the ongoing arrangement. Muhammad Saad

Hi, I can help maintain and evolve your existing iOS app while ensuring stability and code quality, especially when working with an established backend. I’ve worked on similar maintenance-heavy iOS projects where we improved API reliability and reduced regressions through better testing, though some legacy backend parts needed careful refactoring. I’d approach this by keeping changes isolated to small, tested updates and using Git workflows to minimize disruption, with the biggest improvement coming from thorough regression testing before each release. I’ll document my work clearly and always flag risks early so you can review before proceeding. The goal is to keep the app stable and easy to maintain without introducing new issues. If the scope matches, I can start right now. Thanks, Denis.

I've maintained and enhanced complex iOS apps with existing PHP backends for three years, working directly with Yii2 APIs, MySQL schemas, and CI/CD pipelines similar to your setup. I'll isolate issues via Git branching, reproduce locally, then patch or extend the codebase while keeping session stability and API contracts intact. For backend changes, I'll modify Yii2 models/controllers sparingly, validate with staging CI runs, and avoid introducing tech debt during hotfixes. Code reviews will enforce clean architecture before merging to main. Available for immediate start. Thanks, Andrii

I have solid experience maintaining and enhancing existing iOS applications, especially in long‑term setups with CI/CD, Git workflows, multi‑environment pipelines and backend coordination. I’m comfortable working inside established codebases, investigating issues independently, and delivering stable, well‑tested features that don’t break existing flows. I’ve worked on apps involving API integrations, MySQL‑backed services, and PHP/Yii2 adjustments when needed. My focus is always code quality, structured commits, clear communication and consistent progress. I’m used to task‑based collaboration, delivering updates every 48 hours, and handling urgent production fixes when required. I can share App Store links and GitHub repos upon request. I’m available part‑time across five working days for discussions, follow‑ups and batch‑based delivery. I also have basic experience with PHP/Yii2, enough to handle small backend fixes when necessary. If you want, I can start by reviewing your current codebase and proposing a stable workflow for weekly maintenance, new feature development, or bug investigation.
