Hey, I'm Manual QA with 3+ YEARS of Experience and 5,000+ HOURS of hands-on manual QA across web, mobile, and API products - 100% Job Success on Upwork. I help SaaS, e-commerce, and logistics teams ship stable releases by owning the full QA cycle, catching issues before users do, and writing bug reports developers actually want to read.
I work best on long-term contracts (3+ months, part-time or full-time) where the team needs a reliable QA engineer who runs the testing process independently - from test plan to release sign-off - without constant handholding.
WHAT I DO:
- Functional, regression, smoke, exploratory, and UI/UX testing on web and mobile - API testing with Postman - validating contracts, integrations, error handling - Mobile QA on iOS, Android, and iPad (real devices + BrowserStack/LambdaTest) - Test case design and maintenance in TestRail - Cross-browser and cross-device coverage - Bug reporting in Jira with clean repro steps, evidence, severity, and retest notes - Design verification against Figma - catching UI and UX issues before they ship - Release sign-off and post-release verification
TOOLS I USE DAILY:
TestRail · Jira · Postman · Figma · BrowserStack · LambdaTest · Salesforce · Stripe · Amplitude · Browser DevTools · Slack
WHAT I'VE SHIPPED:
- FunnelCraft Studio (Jul 2024 - Jan 2026, ~1.5 yrs). End-to-end QA for digital products with funnel-based sales - landing pages, checkout, upsells, and post-purchase flows on web and mobile. Validated Stripe, Reteno, and Amplitude integrations via Postman. Built and owned the full TestRail suite.
- King Dispatch (Aug 2023 - May 2024, ~10 mo). QA for a logistics web platform integrated with Salesforce. Tested load creation, driver assignment, status tracking, and Salesforce data sync. Verified API contracts and ran full regression before each release.
- PulseNote (Mar 2023 - Dec 2024, ~1.5 yrs). QA for a cross-platform mobile app on iOS, Android, and iPad. Validated sign-up, login, data sync, offline mode, and push notifications across real devices. Built the TestRail suite from scratch and used Postman for auth and sync API checks.
HOW I WORK:
Week 1: I review your product, requirements, and existing test artifacts (if any), then deliver a short test plan covering scope, priorities, and risk areas.
From week 2: structured testing in your sprint cadence. Bug reports in your tracker as I find them, regression before each release, and weekly summaries so you always know where the product stands.
I overlap with EU and partial US business hours and respond within a few hours during the working week.
LET'S TALK:
Send me a message with what you're building and the area you want tested first. I'll come back with questions, a recommended scope, and a clear estimate - no pressure, no bot replies.

🛡 GUARANTEED 10-20% total revenue per user growth if I accept your project OR performance-based CRO 🤘🏻 Worked with Microsoft, YC startups, $500 million+ eCommerce (Prom, UIA..), unicorns (PapayaGlobal, SyteAI...) - but 70% of clients are SMB. 👨🏽🚀 Run A/B tests on 127 million users
After working for the most famous CRO agencies as a freelancer, I co-founded my CRO agency Conversionrate.store which is in the TOP-10 in the USA based on a number of clients' traffic under management (127m users per month)
📞 BOOK TIME FOR A CALL with the Calendly link below and get 3 recommendations on how to increase conversion rates for FREE calendly.com/crocallwithgleb/3-cro-recommendations
Or read below to learn how our CRO process works:
1️⃣ We find WHERE IS CONVERSION BOTTLE-NECK with an in-depth funnel and user journey analysis. The goal is not only to understand where your website leaking the most money but also to find what funnel step or flow blocks the growth of the whole business.
For example, if the bottleneck is on checkout, but you optimize landing pages it will give only 20-50% of potential uplift because users will still drop-off on checkout.
2️⃣ Then UNCOVER THE REASONS OF THOSE LEAKS with a combination of quantitative (Google Analytics/ Mixpanel / Kissmetrics, etc) and qualitative research (heat maps, scroll maps, forms analytics, surveys, user testing, interviewing your sales, marketing, customer support teams, etc.)
What are the users' needs and problems, what objections they have, how they understand the value proposition? CRO is more about persuasion technics and fixing user's problems rather than testing button color.
3️⃣ Creating a hypothesis on how to increase conversion rates/
We choose the tactic of how to ELIMINATE THE REASONS OF BOTTLE-NECK with my collection of 3217 conversion optimization best-practices.
The framework on how to choose optimization tactics is based on studies in neuropsychology, neurophysiology of decision making and online behavior, and good old sales techniques
4️⃣ Develop and QA an A/B test.
Our development team is one of the most experienced in Europe as we have done more than a THOUSAND EXPERIMENTS so far.
We can execute the most complicated experiments and pretty much anything you can imagine on the front-end with all common A/B testing tools (Google Optimize, Optimizely, Visual Website Optimizer, Google Analytics content experiments, etc.).
As for QA, we do a bunch of processes apart from classical web QA to make sure an experiment works as planned, doesn't break anything, and correctly tracked. We roll out experiments by gradually increasing the traffic if the metrics look good, watch 100+ visitor session recordings of alternative versions, double-check the tracking, etc
5️⃣ Analyze statistical significance to make decisions only based on valid data. Typically we estimate our efforts based on revenue per user and look into the nature of the dataset instead of just trusting calculators.
6️⃣ Repeat. The 5 steps above are the typical monthly iteration.
📞 BOOK TIME FOR A CALL with the Calendly link below and get 3 recommendations on how to increase conversion rates for FREE calendly.com/crocallwithgleb/3-cro-recommendations
So CRO is a continuous data-driven process. It's not about a-b testing random best practices. The key is in research.
Starting from 500.000 monthly visitors we could work performance-based. It means that you can pay only for actual growth % according to A/B test results.
🌐 Ask for 3 FREE conversion optimization ideas for your website. Just send me your link to get it.
Guys from Amazon run 40.000 a-b tests per month. Its conversion rate in some categories is 40-50%. This is how they killed the majority of e-commerce competition that had 0,5-1,5%.
Booking.com has 30+ cross-functional CRO teams and runs over 1000+ experiments simultaneously. That's how it became the biggest Adwords client in the world - driving conversion up drives client acquisition cost down.
How about you?
Every website loses money. If you don't optimize the conversion rate daily the growth potential is HUGE.
Send me a link on your website and I'll give you 3 growth hacking hypotheses for FREE.
PS.
🚫 PLEASE DONT CONTACT ME if YOUR PRODUCT HAS NO REAL VALUE or HARMFUL 🚫
I ignore casinos, porn, drugs, weapons, not proven supplements, lenders with extortionate interest rates, things like forex and binary options (98% of people lose money), and any other types of companies that make harm. No matter how big is the budget.
I sell my personal time and it's VERY LIMITED. I would love to grow companies that make a positive impact on humanity like Preply that help people learn different languages or like the biggest chain of fertility clinics in Australia Monash IVF that increases childbirth in the country.
