Hi there, I’m excited about the Hybrid UI/UX Design and QA Engineer role. I’ll own the full design-to-QA cycle for your mobile-first web app, starting from interpreting requirements and reference screenshots to delivering production-ready designs (Figma or clean frontend HTML/CSS/JS). I design mobile-first, ensuring layouts scale smoothly to desktop and translate well into code. For QA, I’ll write structured test cases from design specs, run them against implemented pages, and provide clear, reproducible bug reports with steps to reproduce and expected vs actual results. I’ll collaborate asynchronously with your dev team to verify fixes end-to-end. My approach: - Thoroughly review requirements and references to establish precise UX intents. - Create detailed, developer-ready designs and/or front-end components that communicate layout and behavior clearly. - Implement responsive rules and accessibility-conscious patterns so the product looks great on mobile and scales on desktop. - Build a QA workflow with test cases aligned to screenshots and specs, then execute and report findings clearly. - Iterate with the team until all pages match the agreed designs and pass QA. What is the expected weekly commitment in hours for this ongoing hybrid design+QA role, and are there preferred tools or frameworks beyond Figma/HTML-CSS-JS we should align with? Best regards,

Any issues will be documented as clear, reproducible bug reports with screenshots and steps to fix, ensuring smooth iteration with your developers. This approach ensures continuity from design intent to final implementation, with strong attention to detail and consistency across devices. Thanks, Asif.

I understand you need someone to handle both UI/UX design and QA for a mobile-first web app, from initial specs through verifying final implementation. Based on your written requirements and reference screenshots, I will deliver polished, clear designs in Figma with strong attention to responsive, mobile-first layouts that scale well to desktop. I’ll also write structured test cases tied directly to the specs to cover both visual and functional points. In past projects, I’ve designed mobile-first web interfaces and closely followed up with QA, catching layout issues and bugs early by verifying implemented pages against designs and raising detailed, reproducible bug reports. This helped teams release smooth, pixel-perfect UI faster. Do you prefer Figma deliverables only or would you also want HTML/CSS prototypes when needed for clearer design intent? Also, do you already have a design system or would creating reusable components be useful here? I am ready to start reviewing your requirements and creating detailed designs and test plans that help you ship consistently high-quality web app screens quickly.

Hi there, thanks for sharing the role. It’s clear you need someone who can move from requirements to solid designs and then verify the build without slowing the team down. I’ve worked on mobile‑first web apps for years and I’m used to switching between Figma, code, and QA. I’d handle the work in small passes: • Review your requirements and screenshots • Build clean mobile-first layouts in Figma or HTML/CSS • Provide clear specs to devs • Write and run test cases once the pages land • Log any design or functional issues with steps and visuals I can start right away and stay flexible on hours since this is ongoing part‑time work. Do you already have a design system or should components be defined from scratch? Greetings, Slavko

Hello, I hope you are doing well. I’m an independent designer and QA engineer who can own the full design-to-QA cycle for a mobile-first web app. I bring a sharp eye for clean, responsive interfaces and a methodical QA mindset to verify implementations against designs, with hands-on experience in Figma and clean frontend code (HTML/CSS/JS). I translate written requirements and reference screenshots into production-ready designs and robust test cases, ensuring mobile-first layouts scale gracefully to desktop. In past hybrid design+QA work, I’ve delivered polished UI specs, built responsive components, and executed UAT with clear bug reports and reproducible steps. I design with code in mind or provide high-fidelity Figma files that communicate intent precisely, and I draft structured test cases to verify visuals and behavior. I can handle the work based on my expertise in Figma, frontend development, and QA, and I guarantee reliable delivery aligned with your specs. I propose starting with a design-to-build sprint followed by a QA sprint, with ongoing iterations as your app grows. Please feel free to contact me so we can discuss more details. I am looking forward to the chance of working together. Best regards, Billy Bryan
