• Established the complete QA process for a newly started crypto custody product, including the project test strategy, testing levels, scope estimation, release-quality gates, and release-readiness criteria.
• Managed a 3-person QA team, including up to 2 direct reports; allocated work, supported recruitment, onboarding, mentoring, and performance reviews, and managed the QA team budget.
• Introduced QA First-Pass Pass Rate and Defect Escape Rate to show whether product quality was improving or degrading and reported release risks and quality status to management.
• Coordinated QA activities with developers, product representatives, and stakeholders; collected and analysed requirements, wrote technical specifications, and prepared or verified user stories and acceptance criteria.
• Built a Playwright and TypeScript API automation framework from scratch using tests, fixtures, services, API clients, DAO, test-data, utilities, and configuration layers; added direct PostgreSQL.
• Supported approximately one production release per month and prevented critical or blocking defects within functionality that passed through the established QA process from reaching production.

• Led QA activities across three products and established company-level testing workflows where a consistent QA and development process had previously been missing.
• Managed up to 7 direct QA reports; distributed work, mentored specialists, supported recruitment and onboarding, and conducted or participated in performance reviews.
• Implemented structured test planning, release-readiness assessment, Scrum and Kanban practices, Definition of Ready, Definition of Done, QA documentation, and transparent progress and risk reporting.
• Increased the average number of completed tasks per sprint from approximately 5 to 9 and enabled stakeholders to see completed scope, remaining work, and release risks.
• Created a Playwright-based automation framework from scratch and remained hands-on in UI, API, backend, integration, and blockchain testing.
• Supported an approximate two-week release cadence and maintained production quality in the tested scope without confirmed critical production incidents.

• Built the complete testing process for a new product from scratch, including testing approaches, documentation, scope planning, effort estimation, and QA release-readiness ownership.
• Performed UI, API, backend, PostgreSQL, and Java/Rest Assured automation work while continuously improving product quality and usability.
• Worked with developers and project stakeholders to reduce release risks and prevented critical or blocking defects in the tested scope from reaching production.

• Established a structured QA process after product acquisition, with detailed planning, progress tracking, risk management, and QA release-readiness ownership.
• Used exploratory testing to recover undocumented product behaviour and provide essential knowledge for migration from monolith to microservices.
• Performed UI, API, backend, database, and Java/Rest Assured automation testing; maintained the tested scope without confirmed critical production incidents.

Executed regression testing for telecommunications and CRM systems, maintained test documentation, and documented results and defects.

• Developed testing strategies and certification-readiness procedures for embedded, application, backend, API, and B2B products.
• Reduced certification and expert-review preparation from approximately 5 working days to 1-2 working days and incident resolution from up to 5 days to approximately 2-3 days.
• Coordinated testing with development, support, and technical-maintenance teams and localised difficult-to-reproduce intermittent defects in two devices.

Earlier engineering and team-leadership experience; managed technical and organisational activities within a technology bureau.
