Maksim Efimov
@maksimefimov
I build scalable QA automation frameworks and lead high-impact quality teams.
SpainWhat I'm looking for
I've led QA automation for Endpoint Clinical, expanding its Playwright suite from 600 to 1,000+ tests, raising regression coverage from about 60% to 85%, and reducing manual regression effort by approximately 50%.
At Claro Analytics, now Wilson Analytics, I built the web automation strategy from scratch across Playwright, Postman, and Pytest. I also designed an AI/RAG chatbot testing approach that combined manual verification and automated validation for context accuracy and compliance.
I've created seven-plus automation frameworks from scratch for SaaS, healthcare, AI/RAG, enterprise, web, and desktop products. My work includes E2E, API, integration, database, performance, visual regression, production monitoring, and CI/CD quality gates.
I've led and mentored QA teams of up to six engineers, hired and trained new teammates, and established automation code-review standards. With a former frontend development background and a Master’s degree in Data Science and AI, I use JavaScript, TypeScript, Python, Playwright, Cypress, and AI tools to accelerate reliable test automation.
