Project experience

More than 7 years of experience in testing: banking, fintech, SaaS, logistics and industry. I don't name clients because I'm bound by confidentiality. I show the sector, scale, problem and result.

fintech

Mobile apps and backend in fintech

iOS, Android, microservices · Agile team 2024-present

problem: Mobile apps and microservices developed side by side need manual and automated testing, and someone keeping QA milestones on track.
what I did: I develop and maintain automated UI tests for iOS and Android apps (Appium, XCUITest, UIAutomator).; I test backend microservices: business logic, APIs and integrations.; I plan testing, keep the schedule and priorities on track, and take part in defect triage and root cause analysis.

result -83% regression time: from 9 to 1.5 person-days

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.

result 80% of main features covered by automated smoke tests <20 open defects thanks to test dashboards

logistics

A system for courier companies and parcel locker networks

startup · REST API · parcel locker application 2023-2024

problem: Most system features had no API-level tests, and the documentation drifted from actual behaviour.
what I did: I wrote more than 60 automated API tests in Java and RestAssured.; I compared API responses with the Swagger documentation and reported mismatches.; I designed and ran performance tests of key services in JMeter under production-like load.

result 60+ API tests, about 70% of main features 100+ defects reported and resolved, saving the team time and money

maritime transport

A system for planning and monitoring vessel routes

enterprise · web application and management panel · two Scrum teams 2021

problem: Manual regression took a large part of every sprint, and the test scope wasn't connected to the team's tools.
what I did: I rebuilt the regression scope and integrated it with Azure DevOps.; I wrote automated regression tests in Java and Selenium.; I analysed business requirements and covered 100% of new features with tests.

result -80% time spent on regression 100% of new features covered by tests

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.

result -50% critical bugs in production 100% test reliability restored after the framework refactoring

regression time thanks to automation: -80%
critical bugs in production: -50%
API tests, about 70% of main features: 60+
defects reported across projects: 450+
