I’m rolling out a new Android app and need fifteen everyday users to put it through its paces over the next month. Your task is simple yet critical: use the app as you normally would, pay close attention to how intuitive the screens feel and whether each feature behaves as expected, then tell me what worked and what didn’t. You don’t need a professional QA background—just an Android phone or tablet, a curious mindset, and the willingness to share honest, detailed feedback. I’ll provide the app link, to test might be updates in app as well that need to update by user. By the project’s close I expect: • Four weekly feedback submissions that clearly describe interface usability strengths or pain points and any functional glitches. • Reproduct...

I need a local technician near North Bay, Ontario, who already works comfortably with the Siemens SiPART DR24 controller to verify every field-to-board and board-to-board connection and every component on one unit that is giving intermittent faults. The focus is on connection and component testing rather than functional or algorithm checks; I want confirmation that every terminal, ribbon, plug, and socket is carrying the right signal with no unexpected resistance, shorts, or breaks, and that every component is functioning as it should. Please arrive with your own calibrated scopes, continuity meters, breakout adapters, or any other diagnostic tools you normally rely on for this class of industrial controller. Once on site you will trace and test each connection, document the readings in a...

The job is strictly performance oriented—I am not looking for security or basic connectivity checks. What matters most is an accurate picture of current network speed so we can benchmark upgrades now underway. Scope of work • Visit the designated office floors and selected public areas that already have access points installed. • Run repeatable speed tests (e.g., iPerf, Speedtest CLI, or equivalent) on both 2.4 GHz and 5 GHz bands, capturing downstream and upstream throughput. • Record signal strength, client device specs, test time, and environmental notes for each location so results are reproducible. • Summarise findings in a short report that h...

I need a seasoned QA tester to put my consumer-facing app through its paces on both iOS and Android. The build is stable, but before launch I want fresh eyes on the experience and solid evidence that everything works as intended. Your mandate is three-fold: • Functional testing – confirm every screen, button, push notification, and in-app purchase behaves exactly as designed. • Usability testing – highlight friction points, confusing flows, or accessibility gaps that could frustrate users. • Performance testing – watch for memory spikes, crashes, and slow load times, then document reproducible steps so my dev team can act fast. I’ll provide TestFlight and Play Store beta links, API keys where needed, plus a checklist of known edge cases; you&r...

I have a consumer-facing web application that needs a fresh, detail-orientated review. To make sure we work well together, I’ll begin with a paid one-hour assignment: a short video call on Freelancer. I’ll share the site URL and two known issues. During that single hour you’ll reproduce both problems and record crystal-clear, step-by-step documentation—screenshots or a brief screencast, environment details, and an “expected vs. actual” summary. If you succeed, the project expands to roughly 20 hours of manual testing per week for the next two to three months. The app is not an e-commerce store; it behaves like a typical SaaS web application, so you’ll be exploring navigation, forms, permissions, and edge-case behaviour. I expect testing on at l...

Senior CRO / Experimentation expert wanted for a paid review of our A/B testing platform. Ongoing panel, US-based preferred. Personyze is a website personalization and A/B testing platform, in market for years serving B2B and ecommerce teams. We are expanding the experimentation side of the product and want senior practitioners to evaluate it properly - not a survey, a real evaluation by someone who runs testing programs for a living. You get a full test account (we provide one, or you register your own) and put the A/B testing module through what you would normally do to evaluate a tool for your own stack: build a test, set up goals and targeting, check how variants are delivered, look at how results and significance are reported, and judge whether you would trust the numbers. We want ...

I’m looking for a practising Lean Six Sigma professional to use the platform against a realistic project and give me honest, critical feedback. This is a methodology and usability review, not a bug hunt and not a marketing task. What you’ll do: 1. Run a supplied demo dataset through a full DMAIC cycle in the platform (≈3–4 hours). 2. Assess whether the tool sequencing, gate structure, and terminology match how you actually run projects in the field. 3. Evaluate the statistical outputs — correctness, presentation, ...

A brief performance summary (launch time, memory spikes, battery impact, obvious ANRs). 4. UI notes on layout breaks, unreadable text, or navigation glitches. If you already work with tools l...

I am preparing to roll out my personal-brand website and need an experienced QA tester to put it through its paces before I go live. Although it’s a branding site, it includes e-commerce style features—customers can browse products tied to my brand, add them to a cart, and check out—so the testing scope mirrors what you would normally do on a full online store. The audience is the general public, which means the site must behave flawlessly across mainstream desktop and mobile browsers, as well as on slower connections. Please focus on three critical flows: • Navigation & search: make sure every menu link, filter, and search result lands on the correct page and responds quickly. • Product pages: verify image galleries, variant selectors, reviews, and any...

I need a seasoned performance-testing specialist to run a focused audit on ShowManager.pro.

What I expect you to do • Profile full page load time across key user flows (landing page, login, dashboard, event setup, reporting). • Simulate realistic traffic with tools such as JMeter, k6, or Gatling and capture waterfall metrics with Lighthouse or WebPageTest. • Isolate front-end, API, and third-party bottlenecks, documenting TTFB, first contentful paint, and fully loaded milestones. • Provide a concise report that explains findings, prioritises fixes by impact, and gives actionable optimisation recommendations.

I have a café POS / restaurant management web application that is already in active use and now needs a fresh set of eyes on every release. I’m looking for a manual QA tester who can jump in part-time, preferably from Chennai (remote is fine), and cover functional, regression and UAT cycles end-to-end. Here’s what the day-to-day looks like: you’ll study the current feature list, build or refine the test cases, run them across desktop and mobile breakpoints, log defects with clear steps and evidence, and verify the fixes once they land. A solid grasp of user roles and permissions is essential because the system serves cashiers, waitstaff, kitchen screens and managers, each with different views and privileges. If you have tested POS or hospitality software before, t...

Deliverables • Executive summary written in plain language for leadership • Technical report detailing every finding, proof-of-concept steps, screenshots or packet captures, and CVSS scores •...
