My name is Oliver Kiessler and I’m a freelance senior full stack developer based in Cologne, Germany. I specialize in building modern web and AWS cloud applications. With many years of professional experience, I’ve worked across a wide range of programming languages, frameworks, databases, and technologies, gaining deep, hands-on expertise throughout the entire software development lifecycle. I’m reliable, highly motivated and enjoy working as part of a team. I’ve successfully contributed to Scrum and Kanban projects and place strong emphasis on "Clean Code" principles and test-driven development. I’m also very familiar with Git workflows and CI/CD processes. In recent years, my focus has been on TypeScript, NodeJS and Angular — technologies I’ve used extensively to build robust, scalable web applications. I’m also AWS-certified and have many years of practical experience with a broad set of AWS services, including Lambda, EC2, S3, ECS, DynamoDB and others.
