Maksym Demyanov

I’m a Senior QA Engineer with 10+ years of experience in high-load systems across FinTech, iGaming, Healthcare, and AI. I design end-to-end testing strategies that improve product stability and reduce release cycles.

I focus heavily on AI-driven product testing—especially large language models (LLMs), AI integrations, and performance validation. I validate prompt behavior accuracy, response consistency, context understanding, and alignment with expected outcomes.

I lead QA processes and teams, optimize testing workflows, and drive automation in fast-paced environments. From building QA processes to introducing AI tools for test case generation, I’ve helped teams cut test preparation time by 30% and improve coverage by 40%.

I also strengthen reliability under pressure through regression, functional, and release testing in high-load environments. My approach includes quality gates, risk management, and continuous testing practices to reduce post-release defects and keep downtime minimal.
