Programming teacher at ITWay, teaching Python, web development fundamentals, and practical problem solving. This experience strengthened my ability to explain technical decisions clearly, communicate with non-technical people, structure learning materials, and break complex development topics into simple, understandable steps. I also prepare practical coding tasks, review student projects, explain debugging approaches, and help students understand how real development workflows are organized.
