We need an experienced iOS developer with strong graphics programming skills to fix critical canvas issues in our professional design app, Patternata. The app is used by designers to create textile patterns for printing, so accuracy and performance are very important. The main tasks include fixing the broken pattern repeating system, making canvas sizing accurate at true physical dimensions and 300 DPI, solving export problems so the full canvas is captured, correcting scaling issues with the text tool, and ensuring DPI consistency across the workflow. You should have at least 5 years of iOS development experience with Swift and UIKit, plus expertise in Metal, Core Graphics, and tiled rendering. Knowledge of DPI and commercial printing requirements is a must. Experience with Apple Pencil and PencilKit integration is also important. The codebase is clean and well-documented, so you can focus directly on solving these issues without dealing with messy structure or unrelated feature requests. If you’ve worked on graphics-heavy iOS apps with drawing, canvas, or professional printing output, please share examples. This is a fixed-price project with budget and timeline to be discussed.

With extensive experience in the field of mobile app development, specifically iOS and Swift coding, I believe I possess the skills and expertise necessary to effectively address and improve the critical canvas issues present in Patternata. Having previously tackled multiple graphics-heavy projects that required designing and rendering accurate print patterns, I fully grasp the importance of precision, performance, and maintaining DPI consistency throughout the workflow. Given my past involvement with Core Graphics and Metal, I have demonstrated my ability to handle the complexities of tiled rendering efficiently. Furthermore, my proficiency in Apple Pencil integration will not only alleviate the scaling concerns linked to the text tool but will also assist in rectifying export problems to enhance the overall utilization of Patternata's functions. My dedication to delivering top-notch work without compromising on quality aligns well with your need for a clean codebase that doesn't sidetrack from crucial fixes by introducing unnecessary changes. Rest assured, I am capable of hitting the ground running as soon as we initiate the project. Ultimately, I understand that you require results within a specific timeline even for this fixed-price project. My commitment to your project will extend beyond its conclusion—I will be available for ongoing support should any issues emerge thereafter. Let's kick-start this project so that we can leverage my skills to enhance Patternata!

HI, I’m an iOS developer with 10+ years of experience and a strong background in graphics programming (Metal, Core Graphics, tiled rendering, DPI workflows). I’ve worked extensively on canvas-based apps with Apple Pencil/PencilKit integration, focusing on accuracy, scaling, and professional printing outputs. I can help you fix: Pattern repeat system Accurate canvas sizing at 300 DPI Full canvas export without cropping Text tool scaling issues DPI consistency across the workflow Quick Qs: Do you have sample pattern files or export specs I can use for testing accuracy? Should exports be optimized for TIFF/PDF or other print formats? Are there any performance constraints (max canvas size, memory targets) I should keep in mind? Happy to share relevant portfolio examples of graphics-heavy iOS apps on request. Let’s discuss scope, timeline, and fixed budget to move forward. Best,
