    Weekly iOS Code Review Lead

    Every Monday our pull-requests pile up and I need a battle-tested iOS Tech Lead—someone who has spent at least a decade deep in both Swift and Objective-C—to give them a sharp, independent review. The scope is straightforward: open the Git repository, step through the outstanding PRs, and leave clear, actionable comments that raise our bar for code quality and standards, tighten performance, and surface any security weaknesses you detect. No mentoring sessions or team training are required; the goal is strictly to refine code, flag problems, and suggest solid fixes before we merge. Typical Monday workflow • Clone or pull the latest branch updates from Git • Review each PR line-by-line, checking architecture choices, memory management, threading, and API usage ...

The first priority is to put every screen and flow under a microscope—especially the Login/Register process, the full payment pathway, and user-profile management—so I know exactly where things break, lag, or confuse users. Also, there is an error with AI api configuration. Once a clear, reproducible bug list is in hand, the same engagement rolls straight into fixing those flaws in the codebase.

    I need the “Dynamic Pricing / Dynamic Price Range” plugin on my WooCommerce store to ignore the regular price and calculate all discounts from the Wholesale Suite price whenever a customer is logged in as a wholesale user.

    I need a dedicated desktop application that will let me monitor and control my inventory from a Windows machine. The system must run smoothly on current Windows versions without relying on a browser or cloud-hosted service. Core functions I expect: barcode or manual item entry, real-time stock level tracking, easy search and filtering, low-friction data import/export, and straightforward reporting that I can save or print. A clean, intuitive UI is a must because it will be used daily. Please build the executable and provide the full source code so I can maintain it long-term. If you already have experience with C#, .NET, JavaFX, or similar Windows-friendly frameworks, let me know; I’m open to whichever stack you feel delivers a stable, responsive result. I will clarify the specifi...

    My production API is running on Node 16, and I now need it fully upgraded to Node 22. The jump breaks several dependencies—some are deprecated, others removed entirely—so the work goes beyond just bumping versions. You will: • Analyse the current dependency tree, pin what still works, and replace or manually migrate anything that no longer compiles under Node 22. • Refactor hotspots you encounter for cleaner, faster execution; I’m aiming for measurable performance gains once the codebase is modernised. The application is an API service only (no UI), deployed through a typical CI pipeline, so the deliverable is a clean, install-and-run repository passing the existing test suite under Node 22. If you’ve already handled major LTS jumps and know ...

    I have attached a detailed scope of work that outlines everything I need. Your task right now is simple: study the document closely and come back to me with one clear, all-inclusive lump-sum price in USD. Alongside that figure, I would like you to outline the following so I can compare proposals easily: • A brief breakdown of major cost drivers (so I understand where the money goes). • The timeline you can commit to from kickoff through final hand-over. • Any key assumptions or exclusions that affect your price. If something in the scope is unclear, flag it early so we can resolve it before you finalise your number. Once we agree on the total, I expect milestones to follow the same structure we discuss in your quotation. Please review the attachment carefully...
