Homayoun Behzadian

Senior Software Engineer



As a senior software engineer with extensive experience in Java, C#, and .NET, I have a proven track record of designing and developing scalable, secure, and maintainable applications and services. I'm also proficient in Typescript for front-end development.

My expertise ranges from monolithic apps to microservices and cloud-based architectures. I prioritize usability, scalability, resilience, and maintainability in my work, while also fostering a collaborative, team-oriented environment. I have experience collaborating with cross-functional teams in agile environments, including Scrum and Kanban methodologies and frameworks.

My commitment to staying up-to-date with the latest technologies and tools is demonstrated by my ongoing learning through courses, newsletters, conferences, and writing on Medium and my co-weblog, SmartLab (in Persian). I enjoy sharing my knowledge through teaching and have recently focused on TDD and CI/CD practices. I value diversity in the workplace and thrive on building innovative apps and services with a team.
