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. ***** • The initial project value of $30 is for the trial phase only. • During the trial, you will be assigned two tasks to evaluate your code quality, problem-solving approach, communication, and overall workflow. • Upon successful completion of the trial, we will proceed with regular task batches under the payment terms described above. ***** ---------------------------------------- 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.

Hello, With years of experience at Our Software, I have honed my skills in PHP and software development, making me an excellent candidate for this iOS maintenance and enhancement role. My portfolio speaks volumes for my ability to work with existing codebases, implement new features, and troubleshoot problems independently. My familiarity with Git branches and pull requests will enable me to seamlessly fit into your Git-based development workflow. While my iOS development expertise remains my primary strength, I am not unfamiliar with PHP backend systems like Yii2, which you mentioned as a plus. Efficiency is key, but so is quality. As a team leader known for implementing clean, maintainable, well-structured codes in challenging environments, I intend to apply the same standards to your project. I value proper testing and believe it is essential for maintaining system stability and code quality - attributes you were seeking in prospective candidates. Additionally, my strong English communication skills make technical discussions smoother, thus ensuring we're on the same page throughout the project duration. Creativity thrives when relationships are nurtured based on mutual understanding and trust - two facets I vow to build with you through this collaboration. Thanks!

A long-term maintenance and enhancement role on an existing pre-production iOS app with a Yii2/PHP backend, MySQL, and dev/staging/production environments on a CI/CD pipeline — task-batched work covering new features, bug fixes, API and backend integration issues, and occasional small PHP changes, with steady weekday availability for follow-up. That batch-based, code-quality-first rhythm is exactly how I like to run ongoing engagements. On approach: I start any task from the existing conventions rather than imposing my own — read the module, branch off Git for the fix or feature, and keep changes tight so diffs stay reviewable. For bug work I reproduce first against staging, trace whether the fault is client-side or an API/backend issue, and fix at the right layer, dipping into Yii2 controllers/models for the small backend changes when the root cause is server-side. New features go in with tests where the code supports them, and I verify through the staging environment before it rides the CI/CD pipeline to production, so stability is protected. For urgent production issues I can be reasonably reachable outside the normal window. Is the iOS app Swift/SwiftUI or Objective-C/UIKit (or mixed), and what's the minimum iOS version you support — that shapes how I handle new feature work? Muhammad Saad

Hey, sounds like you need someone who can actually live inside an existing codebase, not just bolt on new screens. I always start by tracing the bug or feature through the existing flow before touching anything, so I don’t break things that already work downstream. I’ve worked plenty with Git branch workflows and CI/CD pipelines, and picking up Yii2 basics for small backend fixes isn’t a problem at all. What’s the current task batch look like, and is there a repo walkthrough before I’d start?

Ongoing maintenance work like this lives or dies on someone who investigates before patching and doesn't disappear between tasks, that's clearly what you're protecting for with the 48 hour cadence and trial batch. I'm not looking for a one-off build either, longer collaborations where I actually learn a codebase tend to produce better work than jumping between throwaway projects. On iOS specifically, my mobile background runs through native Swift work alongside Flutter and React Native builds, plus real Git branch/PR workflows and CI/CD pipelines (GitHub Actions), so plugging into an existing repo and deployment setup isn't unfamiliar territory. Backend-wise I don't have Yii2 hours specifically, but I've built and maintained production PHP apps with Laravel and WordPress, Yii2's MVC structure is close enough that I'd be productive fast rather than learning PHP from zero. Availability is five days a week for communication and task turnaround, and I'm fine starting at the $30 trial with two tasks so you can judge the code and process before committing further. My usual rate sits around $10/hour, which fits inside your posted range. If that works, send over the trial tasks or the repo access details and I'll get moving.

Hello, I’ve maintained and enhanced several iOS apps built on existing codebases, fixing memory leaks and stabilizing API integrations that were causing crashes in production. The work kept the apps responsive and the backend calls efficient. For this role, I’d handle maintenance the same way—prioritizing clean, tested changes that don’t introduce regressions. I’ll isolate each fix in its own branch, test it thoroughly in staging, and only merge after review. You’ll never face surprises; I’ll flag blockers early and give regular progress updates. The goal isn’t just to ship tasks—it’s to keep the app reliable and maintainable so future updates stay fast and predictable. If the approach sounds right, I’m happy to start with the trial tasks. Thanks, Lazar.

The kind of work you need is exactly where careful iOS maintenance pays off. Joshua here. You need a dependable iOS developer for ongoing maintenance, feature updates, and bug fixes without risking stability. One thing that often gets missed in existing apps is how a small change can break an old flow, so I always trace the full impact before shipping. I would work directly in the current codebase, keep changes focused, and use Git branches, pull requests, and thorough device testing before delivery. I can also review API and backend touchpoints, and make small Yii2 or PHP edits when needed. I am comfortable working across five days a week and can align with your time zone for steady communication. Q: For the trial phase, do you want the two tasks handled in separate pull requests so each one can be reviewed and validated independently? If that fits, I would be glad to discuss the first batch on a quick call.

I noticed that the current CI/CD pipeline may skip unit tests when a fastlane lane is triggered, which can let regressions slip through. I'll add a step that forces the test suite to run on every build and set the Xcode scheme to fail on warnings. Ready to start immediately and will open a fresh branch for the first task batch. A common mistake is editing a view controller without updating its storyboard identifier, which leads to runtime crashes. I always run the app on a clean simulator after each change to catch such issues early. You will see stable builds where new features integrate without breaking existing user flows.

Hello There, We have experience in maintaining and enhancing existing iOS applications with PHP backends, focusing on bug fixes, new feature development, code refactoring, database optimization, and long-term system stability within established CI/CD workflows. Couple of quick questions: - Is the iOS app built with Swift, Objective-C, or a combination of both, and are there any critical modules that require immediate attention? - Since your backend uses PHP, are you working with Yii2 or another framework, and should we also handle server optimization and database improvements alongside the mobile app? Our company has 17+ years experience in IT service development. You might see our profile is new, but not new in this business. Kindly open the chatroom, we even provide you some free additional development if require. Also release the payment once we are finish the task as you prefer. Give us a opportunity and we won't fail you. Thanks, Sandeep K.
