I have a live Shopify app that I’m about to push into wider promotion, and before I do that I want a fresh set of expert eyes on it. Your task is to go through the app exactly as a merchant would, stress-test every corner of it, and hand back a clear, well-structured report that tells me what works, what doesn’t, and how the overall experience feels. Scope of the test • User interface and usability – every screen, button, and message should be intuitive and visually consistent. • Performance and speed – note any sluggish moments, long load times, or stalls. • Security and data protection – confirm sensitive actions (log-in, data saves, API calls) behave safely and expose nothing. Key workflows to cover • Account management: instal...
I need a solid automation suite for my REST-based service and want it written in TypeScript with Cucumber. The API is already live; what’s missing is a reliable, repeatable way to validate each endpoint whenever we push new code. The job centres on building (or extending) a Cucumber + TypeScript framework that can: • hit every current REST endpoint, • assert responses and status codes, • pull test data from configurable files or environment variables, and • output readable reports (HTML or JSON) after each run. Once the core framework is in place, a handful of sample scenarios should demonstrate the pattern so my in-house team can keep adding tests. Clear setup instructions (npm scripts, ts-config, step definitions, feature files) and a brief README are es...

Our enterprise-grade SaaS platform is mid-stream in development and the team now needs structured, part-time project management focused squarely on coordination.

Asana is our single source of truth, so fluency there is essential. You...
My Android app is feature-complete and ready for a round of focused functional testing before I push it to production. I need you to install the current APK on a variety of real devices or well-configured emulators, walk through every user flow, and uncover anything that blocks, crashes, or behaves unexpectedly. The priority for this engagement is functionality; once that’s solid we may explore user-interface or performance audits in a follow-up sprint. I’m looking for clear, reproducible bug reports that include: device/OS details, steps to reproduce, expected vs. actual results, screenshots or screen recordings, and a quick severity rating. Feel free to use the usual Android toolset—ADB, Logcat, Crashlytics, Espresso scripts, or whatever helps you surface issues quickl...
I need a small application that lets me push short project-status messages to three specific business owners on WhatsApp without any fuss. The core idea is speed and reliability: write the update once, hit send, and know it reached the right people. Here is what matters most to me: • A friction-free interface—web, desktop, or mobile, I am open to what you feel will be the most dependable path. • Straightforward contact management for just three recipients, yet flexible enough that I could add or edit contacts later. • A smooth workflow for composing, reviewing, and sending updates; if message templates or scheduling make that smoother, feel free to incorporate them. • Solid delivery—whether you leverage the official WhatsApp Business API, an approve...

I have a custom integration that keeps Total Synergy and Trello in sync through their public REST APIs. Lately I’ve spotted dates drifting out of alignment, so the immediate objective is to pinpoint where the sync is breaking down – I’m not chasing speed improvements yet, just accuracy. Your task is to work through the existing problem case and check API calls, datatable mappings and webhook logic to uncover any instances where the wrong information is being pushed or pulled. The spotlight is on date fields (start, due, modified) but any other incorrect data you uncover should be noted. Deliverables • Find and fix the issues on the fields the customer has noted some discrepancies I’ll supply access to total synergy, trello and the integration database.
My current C/C++ codebase is functionally solid but far too heavy on RAM. I want it slimmed down without sacrificing stability, so your primary mission is to diagnose and trim memory consumption across the project. Here’s the picture: • The focus is squarely on C and C++ sources. • I need concrete, measurable memory savings—ideally demonstrated through before-and-after profiling runs. • Speed and readability improvements are welcome side-effects, but memory is the KPI that matters. How we’ll work: 1. You begin with a deep dive using the tools you trust—Valgrind, AddressSanitizer, massif-visualizer, perf, or similar—to chart current heap/stack behaviour. 2. From those findings you’ll redesign data structures, apply smarter algorithm...
