Quality assurance process

I test critical paths first: login, pay, submit, delete account.

Edge cases matter - empty carts, expired sessions, double clicks on pay.

Automated tests where ROI is clear; exploratory testing where UX is new.

Polish releases: PL/EN switching, local payment sandboxes, mobile carriers.

US releases: analytics firing, cookie consent and Safari-specific quirks.

About me

I'm Viktar Liukevich

Full-stack developer · 15+ years creating web

I am Viktar Liukevich - a developer who runs QA in Warsaw because I also fix what I find. Test plans, regression passes and API checks before your customers hit a broken checkout.

I test critical paths first: login, pay, submit, delete account. Edge cases matter - empty carts, expired sessions, double clicks on pay. Polish releases get PL/EN and local payment sandboxes; US releases get Safari quirks and consent flows.

For large browser matrices, dedicated accessibility audits or long-running automated suites, I bring in QA partners in Poland, Europe and the USA - manual testers and Playwright/Cypress engineers under NDA. I triage bugs and ship fixes; they expand coverage when scope demands it.
