Hi, I’m Yusuf Ozturk. I’m a Software Test Architect and SDET Lead with 10+ years of experience designing and scaling enterprise-grade test automation frameworks across fintech, SaaS, bioinformatics, defense, and more. I consistently deliver faster release cycles, reduce production defect escape rates, and optimize continuous testing across cloud-native environments. I’ve built scalable automation ecosystems that have driven multi-quarter improvements in velocity and quality, and I’ve led cross-functional teams through complex QA transformations. My focus now includes AI-powered test automation, including prompt validation, hallucination detection, and agentic workflow testing with LLMs. I enjoy mentoring engineers, aligning test strategies with sprint goals and OKRs, and delivering practical AI quality frameworks that improve tool-call accuracy, context retention, and end-to-end reliability in production systems.…Hi, I’m Yusuf Ozturk.
