Manual and exploratory testing
I'll go through your app the way a user would and look for what the scripted scenarios miss. Every defect comes with steps, environment and priority.
- web
- iOS
- Android
I'll test your app before your users do
I help startups, software houses and companies without in-house QA ship apps without surprises in production. I'll test your web app, mobile app or API, automate regression and build a testing process from scratch.

Services
Seven ways I can help. Each can be combined with the others and matched to your release rhythm.
Web application test automation
I'll write E2E tests in Playwright or Cypress and plug them into CI. In one project this cut regression time by 80%.
- Playwright
- Cypress
- Selenium
Mobile app testing
I'll test your app on iOS and Android, on real devices and emulators. Automation is built on Appium, XCUITest or UIAutomator.
- Appium
- XCUITest
- UIAutomator
API testing
I'll check contracts, JSON and XML validation and error scenarios in REST, SOAP and GraphQL. In one project, 60+ API tests covered about 70% of main features.
- Postman
- RestAssured
- SOAP UI
Performance testing
I'll prepare load scenarios in JMeter and check at what traffic the system slows down. You'll get a report with response times and error thresholds.
- JMeter
- Grafana
- CI
QA audit and process setup
I'll assess how you test today and propose a strategy, a test plan and defect triage rules. I'll build regression from scratch and a dashboard the team will actually read.
- strategia testów
- plan testów
- Jira
QA support in your team
I'll join your team for an agreed number of hours, for example before a release. I work in your repository, tools and sprint rhythm.

How we work together
From a project description to a report before release. No lengthy negotiations and no commitment to start.
- step 1
Project description
You fill in the form: platforms, deadline, what you already test.
- step 2
Scope and quote
We agree on scope and environments. You get a quote and a test plan.
- step 3
Testing
I test and report defects as I go, in your tool.
- step 4
Report
What was tested, what wasn't and which risks remain before release.
- step 5
Regression
Optionally: regression automation and support for future releases.
Project experience
More than 7 years of experience in testing. I don't name clients because I'm bound by confidentiality. Instead: sector, scale and result.
SaaS
An omnichannel communication SaaS platform
Node.js, microservices · SMS, WhatsApp, email · international team 2022-2024- problem
- The team had no planned testing process and no automated smoke tests, so defects surfaced late.
- what I did
- I planned the whole testing process, the strategy and regression scope from scratch.
- I wrote automated tests in TypeScript (Cypress, Playwright) for smoke testing and API tests with GraphQL.
- I built test dashboards that helped bring open defects down to fewer than 20.
- TypeScript
- Cypress
- Playwright
- GraphQL
- Postman
- GitLab CI
result 80% of main features covered by automated smoke tests <20 open defects thanks to test dashboards
banking
A bank's online banking and mobile apps
web, iOS, Android 2019-2021- problem
- The bank's core applications needed consistent test coverage across releases and fewer critical bugs in production.
- what I did
- I designed regression scopes for new features and ran regular regression cycles on web and mobile.
- I automated functional, regression and smoke tests in Selenium and C#.
- I analysed backend and mobile app logs (Linux, Logcat) and tested APIs in SOAP UI and Postman.
- C#
- Selenium
- SOAP UI
- Postman
- Jenkins
- SQL

About me
I've been testing apps for over 7 years
I'm a Senior QA Engineer with more than 7 years of experience. I currently test mobile apps and backend in fintech. Before that I tested a bank's online banking and mobile apps, an omnichannel communication SaaS platform, a logistics startup's parcel locker system and software for maritime transport.
I automate in TypeScript, Java and C#, build regression from scratch and mentor testers in the teams I join.

How much does app testing cost?
I don't have a price list, because the cost depends on scope: the number of platforms, environments and whether you need automation. Describe your project in the form and you'll get a quote and a proposed test plan in reply.
Can you join the team just for a release?
Yes. I also work hourly, for example for two weeks before a release. I join your Jira, repository and team meetings.
Do you test apps that are already in production?
Yes. I start with exploratory testing and a review of production tickets, then suggest which scenarios are worth covering with regression.
Which tools do you report defects in?
The ones your team uses. Every report has steps, environment, expected and actual result, and priority.
Will you sign a non-disclosure agreement (NDA)?
Yes. That's why the site doesn't name clients, only sectors and project scale.
Got a release in a few weeks?
Describe your project in the form. I'll reply with questions about scope or an initial test plan.
