QA ENGINEER

PROFESSIONAL SUMMARY

QA Engineer with 5+ years of experience across e-commerce,
logistics, fintech / payments, games, medical, AI / social and
mobile domains. Blends strong manual testing (functional,
regression, integration, UAT, exploratory) with test automation
(Playwright + TypeScript, Page Object Model) and API testing
(Postman, Swagger). Backend-aware tester comfortable with
NestJS / TypeORM / PostgreSQL — reads logs and Sentry traces
to reproduce issues and drive root-cause analysis. Actively
integrates AI / LLM tooling into the QA workflow to accelerate
test documentation, test design and automation scaffolding,

API Testing: Postman, Swagger / • Built custom, reusable AI workflows that encode internal
OpenAPI, proxy tools QA conventions and auto-generate Excel / Word checklists,
Security Testing: CSP / clickjacking, Postman collections and Playwright POM scaffolds from

SkillUP (2019) • Prometheus (2021) •
Udemy (2023) • Tested payment integrations (LiqPay, NMI) with sandbox
cards and logistics / shipping APIs (Nova Post and partner
carriers), diagnosing carrier and gateway errors.

SELECTED PROJECTS

• Spraga — international online store — multi-country e-
commerce for an international kombucha brand on
WordPress / WooCommerce + WPML, with localized
storefronts for Czech, Portuguese, German and Spanish
markets (spraga.cz / .pt / .de / .es). Tested the full purchase
funnel — catalog, product variants and pack sizes, cart,
wishlist, checkout and multiple payment methods; account
flows (registration, login, password recovery); newsletter
discount-coupon and free-shipping-threshold logic; cross-
locale currency, translation and content consistency across
domains; cross-browser and mobile-responsive layouts; and
GDPR cookie-consent and legal pages.
• Infatuated.ai — AI / social platform — AI image-generation
and character-creation testing on a cross-platform social app
with a freemium model. Ran security testing (clickjacking via
CSP headers, JWT exposure in OAuth callback URLs, CTDPA
geo-compliance), analyzed backend errors (OAuth callback
failures, duplicate-key constraint violations, 500s on chat
endpoints), and produced large structured Excel checklists
(Private Gallery 92, Discover 145, video-creation tools).
• rePost.global — logistics SaaS — international shipping SaaS
for Etsy and marketplace sellers. Tested Nova Post and

partner-carrier APIs, marketplace integrations (eBay, Etsy,
Shopify, Amazon — OAuth and order sync), and the Public
API (parcels, rates, users, finance, RBAC) for auth, validation
and permission handling; triaged Sentry / PHP errors with
root-cause analysis; authored regression checklists (211
cases for rePost, 100 for the admin panel) in Excel and
Word.
• HOP Energy — multi-region energy provider — region-
based testing of a multi-branch WordPress site for a
Northeast-US heating-oil, propane and HVAC provider.
Verified branch / location pages and ZIP- and county-based
service-area logic, region-specific content and pricing plans
(CAP / Fixed / Variable), branch contact details, and quote /
contact forms with reCAPTCHA — across browsers and
mobile-responsive layouts for each region.
• Help Portal — test automation (Claude Code) — built a 183-
test Playwright + TypeScript suite (Page Object Model, 6
Page Objects) from an SRS using Claude Code on macOS —
multi-browser config (Chromium / Firefox / WebKit), trace /
screenshot / video on failure, HTML + JSON reporting and a
GitHub Actions CI workflow. Also used the agent for visual
QA, comparing the live site against Figma designs.
• E-commerce — fabricsocean (fabrics, beads and crystals SPA
store) — built a 243-case functional checklist and extracted
SVG design assets from Figma exports; OjaExpress (ethnic-
grocery delivery) — validated checkout, refunds,
performance and usability across web and mobile.
• Payments — LiqPay sandbox integration testing (test cards,
prioritized P0–P3 checklist with a GO / NO-GO summary),
NMI gateway AVS / CVV behavior, card-sharing fraud
detection, and SQL-injection / CSRF security checks.
• Mobile & Games — Nutrihorse (horse-owner app —
notifications, iOS / Android compatibility), SwishHoop
(sports-training app with Bluetooth device integration),
RobotWars and other game titles (gameplay, ads
monetization, crash-log / analytics validation), plus NDA
medical and receipt-storage apps.
