S U M M A RY

Senior QA Engineer and QA Team Lead with 7+ years in fintech: hands-on trading on financial and crypto markets, followed by QA on exchanges,
trading engines, DeFi platforms and payment systems. I build AI-assisted test automation: E2E and API tests in Playwright and TypeScript, using
Claude Code to speed up script creation, refactoring and coverage growth, while test design and review stay mine. Most recently led QA across 3
concurrent projects with zero critical regressions at release; built an internal toolkit that cut the team’s manual operations by ~60%; set up QA
processes, CI/CD and the QA team from scratch.

refactoring, growing automated coverage faster with the same team.
Integrated automated test suites into CI/CD (GitHub Actions) with reporting and quality gates.
Built an internal GUI toolkit for deployments and service management, reducing the team’s daily manual operations by ~60%.
Established the QA process from zero: test strategy, templates, metrics, onboarding; built and grew the QA team.
Performed performance and load testing of high-volume trading systems with K6 and JMeter; deep API testing with Postman and Swagger.

QA Engineer
Applicature (Blockchain Development Studio) | 2021 – 2023
Tested blockchain web and mobile apps, DeFi platforms and crypto payment systems end to end.
Conducted SQL-based backend validation of blockchain transactions and payment flows.
Ran load and stress tests on payment and API layers with JMeter; worked in Agile/Scrum with Jira.
Created and maintained test documentation: test cases, checklists, bug reports, weekly QA reports; mentored junior QA engineers.

Financial Markets Trader / Trading Product Tester
Financial and crypto markets, trading platforms | 2018 – 2021
Traded actively on financial and crypto markets: order types, liquidity, slippage, fees and risk management.
Tested trading products (exchanges, terminals, wallets) as an expert user: beta and acceptance testing, detailed bug reports.
Contributed to test strategies from the trader’s perspective: order-execution edge cases, high-volatility scenarios, balance and fee calculations.
Gained the domain foundation behind later QA work: transaction flows, matching logic and exchange mechanics.
