    I already have a lightweight Chrome extension that takes a list of names from Excel, lets me tweak the list, and then spits out a plain-text draft I can paste anywhere. I now need one extra step: after the draft appears, I want to trigger an additional action with a single click. There is currently no button in the interface for this, so your task starts with adding one. Once the button is in place I’ll walk you through the exact JavaScript logic it should run—nothing complex, and all within the standard Chrome extension APIs. If you’re comfortable navigating manifest files, popup scripts, and background messaging, this should be a quick tweak. Deliverable • Updated extension code (popup HTML/CSS/JS and any background or content scripts) that introd...

    I have a batch of Android tablets that refuse to complete their normal software update because I can no longer sign in to start the process.

The work will be finished once every tablet can: • sign in without errors • download and install the current official system update • reboot and operate normally afterward If you have proven experience recovering locked-out devices and pushing OS or firmware updates,...

    I have an Android build that is feature-complete and ready for a final quality sweep before it hits the Play Store. What I need from you is twofold: 1. Manual validation • Run my full functional pass and documented edge-case matrix across a healthy mix of real Android devices and OS versions (no emulators for this stage). • Log every deviation from the acceptance criteria with crystal-clear steps to reproduce, screenshots or screen-captures, device/OS details, and any relevant logs so my devs can fix fast. 2. Automated regression coverage • Build an Appium-based suite that focuses on the critical user flows I will share. • The suite must be reliable enough to drop straight into our CI pipeline (GitHub Actions today, but a simple shell...

    ...technically credible, and institutional. Experimental is welcome, but the final mark should not look like a gaming/esports logo. The IPTO palette to test is #38495E, #5A789A, and #829EBE. The final concept must also work in monochrome and grayscale. Avoid: generic three-ring chains, topology that only appears Borromean from one screenshot, four obvious letters, stock circuit textures, overly glossy chrome renders, literal technology icons, literal Pentagon imagery, or decorative complexity that cannot simplify to a strong vector mark. REQUIRED DELIVERABLES 1. Topology / construction sheet validating the Borromean relationship. 2. Three initial concept directions, all topologically correct, varying Möbius treatment, surface treatment, and hidden-letter strategy. 3. Two refi...

    I already have a reference Chrome extension that automates web-scraping tasks, and I need an exact replica—interface, behaviour, and results must match 100 %. The extension grabs structured data from targeted pages, so every selector, background script, and content script has to mirror the original. I will provide access to the live extension, sample URLs, and the specific data points it extracts; your job is to recreate the same flow under a fresh codebase that is Manifest V3 compliant and free of third-party licensing issues. Because I need this ASAP, please be prepared to start right away, show rapid progress, and hand over a fully functional CRX plus readable source code. I will verify that: • the scraped output is identical to the reference for the sample pages, ...

    I need a lightweight, responsi...same template (a hero-style banner or a fixed sidebar slot is fine) that I can swap out with different promotions later. Code expectations Hand-write modern, semantic HTML5 and modular SCSS/CSS that I can re-skin quickly just by tweaking variables. No heavy frameworks; pure HTML/CSS with a sprinkle of vanilla JS only if it helps the CTA or banner behave responsively. Please test in the latest Chrome, Firefox, Safari and Edge. Deliverables – Zipped folder containing well-commented HTML, organised asset folders and compiled CSS – A short read-me outlining class-section structure, where to drop ad creatives and how to recompile styles I’ll review on clarity of code, fidelity to the energetic aesthetic and flawless responsivene...

    I need an experienced...pass/fail checklist. The app supports Email, Google, and Sign in with Apple, includes a free trial period during onboarding, and relies on several multistep forms. Your job is to verify each flow, catch crashes, and spot any UI rough edges before release. Please be ready to: • Use physical phones and tablets running the latest and one major-version-back OS • Capture concise bug reports that include screenshots or screen recordings, device/OS details, and app build number • Re-test quickly after fixes are pushed and keep clear history of results in our shared sheet If you already have a track record testing productivity apps and feel comfortable diving in this week, I’d love to hear how many devices you can cover and when yo...
