Party Pocket, my live vendor-marketplace app for events, needs a reliable developer who can grow with it. The immediate priority is clear: fix existing bugs and boost performance on iOS so users experience fast loading, smooth navigation and zero crashes. Once the core is stable, we will roll into UI/UX refreshes, expanded booking flows, richer vendor dashboards, subscription logic and eventually an Android build. First milestone – performance & stability • Pinpoint and squash critical bugs on the current Swift codebase • Optimise memory usage, startup time and API calls • Implement basic regression tests and crash-report monitoring • Deliver a short report each week outlining issues found, fixes applied and next steps After we hit an acceptable crash-free rate and sub-second screen transitions, we will move on to the visual overhaul and new feature work. I see this as an ongoing partnership, potentially full-time as revenue grows, so clean, well-documented code and proactive communication are vital. Tech environment The app is built natively for iOS with standard Apple frameworks and a cloud-based backend. If you are comfortable with Swift (or SwiftUI), RESTful APIs, payment integrations and scalable architecture, you will feel at home here. Familiarity with Firebase or AWS is a plus as we plan for larger user spikes. Success for the first phase is simple: the latest build passes TestFlight without crashes, scores noticeably better on performance metrics, and receives positive beta feedback within four weeks. Let me know how you would approach the bug sweep, the tools you prefer and your typical cadence for weekly updates.

Hi! This sounds like a great opportunity getting the app stable and smooth first is exactly the right move before adding new features. The focus here is making sure users feel speed, reliability, and zero friction. Here’s how I’d approach it: • Go through the app to identify crashes and performance bottlenecks • Improve loading speed and smooth out navigation • Optimize API calls and reduce unnecessary processing • Set up crash tracking so issues are caught early • Add basic testing to prevent regressions • Share weekly updates with clear progress and next steps Once everything is stable, we can move confidently into UI improvements and new features. I focus on making apps feel fast, stable, and user-friendly. Quick question: are most issues happening during specific flows (like booking or browsing), or across the app? Would love to help you turn Party Pocket into a smooth, reliable experience users enjoy. Best, Jasmin

I can help with this, I will stabilize your Swift codebase — hunting down crashes, reducing memory leaks, and optimizing API call patterns — then deliver weekly reports covering each fix and its impact on performance metrics. For the bug sweep, I will start by integrating Firebase Crashlytics (if not already present) to rank crashes by frequency and user impact, then profile startup time with Instruments to catch retain cycles and redundant network calls. This data-driven approach ensures the highest-impact fixes land first, getting you to a crash-free TestFlight build faster. Questions: 1) Is the UI built with UIKit, SwiftUI, or a mix of both — and is a SwiftUI migration on the table for the visual overhaul phase? Looking forward to your response. Best regards, Kamran

Hi, the right way to handle this first phase is to treat it as a stability and performance pass, not just bug fixing. A real flow would be: user opens the app -> initial data loads for events and vendors -> navigates between listings and detail screens -> interacts with booking or vendor profiles -> returns to previous screens without reload delays or crashes. That full path is what needs to feel fast and consistent, not just isolated screens. These apps often look fine in testing, but fail when multiple API calls, heavy images, and navigation stack issues combine under real usage. One real issue is memory pressure building after repeated screen transitions, leading to slowdowns or crashes, so I would handle it by profiling allocations, optimizing API usage, and tightening view lifecycle handling. The part to get right early is the performance baseline and crash tracing setup, because that drives every fix that follows.

Hi there, I’m Shamshad, and I’m excited to help Party Pocket reach a stable, fast, crash-free iOS experience while laying a solid foundation for future UI/UX updates and new features. My plan starts with a focused bug sweep and performance uplift across the current Swift codebase: identify memory hotspots, reduce startup time, optimize API usage, and ensure smooth navigation with sub-second transitions. I’ll implement lightweight regression tests and crash monitoring from day one, and deliver a concise weekly report detailing issues found, fixes applied, and the next steps. Approach: I’ll begin with a targeted bugs-and-slow-path analysis using Xcode Instruments, Firebase/Crashlytics crash reporting, and network profiling to pinpoint bottlenecks. I’ll establish a minimal regression test suite and a simple, scalable crash-report workflow, then iterate toward a crash-free build in TestFlight. Documentation will be clean and accessible for future contributors, and I’ll maintain proactive communication with weekly status updates. After stabilizing core performance and reliability, I’ll align with your plan for a visual overhaul, enhanced booking flows, and vendor-dashboard features in subsequent phases. What tools do you prefer for error tracking and performance monitoring (e.g., Firebase Crashlytics, Sentry, Instruments), and what is your preferred cadence for weekly updates? Are there any known flaky APIs or third-party SDKs we should account for from the outset? What ar

Hi I have strong experience with native iOS development in Swift, API-driven mobile apps, and stabilizing existing codebases that need better performance, lower crash rates, and cleaner long-term structure. The main technical challenge in Party Pocket is not just fixing visible bugs, but identifying the deeper causes of crashes, slow screen transitions, memory pressure, and unstable API behavior across real user flows. I would approach this by auditing the current Swift codebase, profiling startup and navigation performance, reviewing network and threading patterns, and tightening error handling so the app becomes measurably more stable and responsive. I’m also comfortable adding practical regression coverage and crash-monitoring tools so fixes are validated instead of becoming temporary patches. Once the first milestone is stabilized, the codebase can support cleaner UI/UX improvements, booking flow expansion, vendor dashboard enhancements, subscription logic, and a smoother path toward Android later. My focus is always maintainable code, clear documentation, and weekly technical updates that explain what was found, what was fixed, and what should be prioritized next. This fits well with an ongoing partnership where reliability and proactive communication matter as much as feature delivery. Thanks, Hercules
