I'm Josip Lončar, an ISTQB-certified software tester with over six years of QA experience. I specialize in manual testing, defect tracking, and collaborating with cross-functional teams to deliver reliable healthcare software. I design functional, regression, and exploratory test cases, perform release validation and smoke testing in agile cycles, and continually seek ways to improve QA processes for higher quality products. Outside of work, I’m an avid gamer and football fan, and I enjoy sharing knowledge to help teams grow their testing skillset and deliver great user experiences. In my roles, I’ve focused on building robust test plans, maintaining thorough documentation, and ensuring client needs are met through effective testing strategies. I’m passionate about QA excellence and user-focused quality improvements, and I enjoy mentoring teammates to nurture a culture of quality across projects.
