Hi, Your marketplace app is already in pre-production with Swift (iOS) and a PHP Yii2/MySQL backend — so this phase is all about smart stabilization, refactoring, and preparing clean builds for App Store release. I’ve worked on taking ownership of existing codebases, fixing edge-case bugs, improving performance, and managing backend services without disrupting current infrastructure. I’m comfortable handling Git workflows, server configs, and long-term maintainability so your launch is smooth and scalable. I’d be glad to step in as the technical owner and grow with the product post-launch. Looking forward for your positive response in the chatbox. Best Regards, Arbaz T

Hello, Your app is already close to launch, so the priority now is technical stability, clean architecture, and a smooth App Store release. I can take ownership of the existing codebase by reviewing the Swift iOS project and the PHP Yii2 backend to identify bugs, performance issues, and areas that need refactoring before production. I’ll focus on stabilizing the marketplace flow such as listings, messaging, and purchases, while improving backend reliability and database queries in MySQL. I’m also comfortable managing Git workflows, server configuration, and handling TestFlight builds and App Store submissions. You’ll receive clear progress updates, structured bug tracking, and ongoing support as the platform transitions from pre production to live operation. I’m ready to begin reviewing the codebase. Best Regards, Shabahat Habib...

Hi, This sounds like you’re at the most important stage — not building from scratch, but making sure everything is stable before launch. That phase needs someone careful, not just fast. I’m comfortable stepping into existing codebases and reviewing them properly before making changes. I’ve worked with Swift-based iOS apps and PHP backends before, so handling Swift + Yii2 + MySQL together isn’t an issue. Here’s how I’d approach it: • First, review the architecture and identify weak points • Fix bugs and stability issues without introducing new ones • Refactor only where it actually improves performance or maintainability • Clean up backend logic if needed • Manage builds and prepare for App Store release properly Since this is technical ownership, I’d treat it seriously — not just “task-based” work. I’m fine starting part-time and supporting ongoing improvements after launch. The budget range works for an initial stabilization phase, as long as expectations and workload are clearly defined. If this aligns, I’d suggest starting with a short technical review of the current codebase and outlining a 2–4 week stabilization plan.

Hello there, I’m a solo developer with solid iOS Swift experience and hands-on backend chops in PHP Yii2 and MySQL. I’ve led end-to-end fixes and architecture tweaks, always focusing on stability and maintainability, while keeping the user experience smooth for launch-readiness. I’ve previously owned similar marketplaces: I’ve fixed critical bugs, refactored legacy code for performance, streamlined builds, and managed App Store submissions, handling both client apps and server/config layers to deliver reliable releases without downtime. I can own the project going forward: review the current codebase, stabilize the app, perform targeted refactors, optimize backend/services, and manage builds and releases. I’ll keep changes incremental and well-documented to ensure a clean transition into ongoing development. Please feel free to reach out so we can discuss scope, timelines, and your launch plan. I’m looking forward to the chance to work together. Best regards, Billy Bryan

Hey — saw your post about needing a technical owner/dev for your existing iOS marketplace app with a PHP Yii2 backend. Keeping an older stack stable while still shipping new features is usually where things start to drag and break. Quick question before I suggest an approach: Do you already have a clear list of current bugs / tech debt items, or is part of this role to audit the app and define that roadmap from scratch? I’ve led and maintained production iOS apps tied to legacy PHP backends before, including refactoring, stabilizing, and then iterating without downtime. If you can share the current App Store link, backend repo details, or any existing docs/specs, I can review and give you a concrete plan on what needs to happen first.

Hello there What are the main challenges you see in stabilizing and fixing bugs in the existing iOS app and backend? How do you envision managing ongoing improvements and support after launch? Tackling bugs and stability issues is complex because existing code might have hidden side effects. Managing continuous updates needs clear structure to maintain performance and user experience. I would prioritize reviewing the full codebase to identify risks and plan targeted fixes. Then I would set up a streamlined process for builds, testing, and releases to keep the app stable. I would be happy to discuss further on chat.

I have solid experience with Swift (Xcode), PHP (including MVC frameworks), and MySQL-backed systems. I’m comfortable reviewing existing codebases, fixing stability issues, refactoring where needed, and preparing apps for App Store release. I’ve also handled post-launch maintenance and ongoing improvements before. Your setup (Swift + Yii2 + MySQL) is straightforward for me, and I can work independently while keeping things organized and documented. I’m available part-time to start and open to a long-term collaboration as the app grows.
