About Me

I’m a Senior QA Engineer with 10+ years of experience improving product quality across web, mobile and backend platforms. I work end-to-end - from refining requirements and designing test strategy to coordinating regressions and signing off releases.

Over my career I’ve delivered QA for consumer apps (1.2M+ MAU), ensuring predictable, low-risk releases and maintaining zero high-severity production issues for 6+ months on a high-traffic product. I focus on preventing issues early, aligning testing with business goals, and giving teams the clarity and confidence they need to ship.

I’m comfortable building QA processes from scratch, mentoring engineers, and integrating AI/LLM-based tools to speed up analysis, documentation and test design. I thrive in environments where quality matters, requirements evolve, and a reliable product is key to success.

Based in Oviedo, Spain (remote global). Fluent in English, Serbo-Croatian, Russian. Intermediate in Spanish.
