About

Junior software developer specialized in web development and cloud solutions, with a background in Web Application Development (DAW) and an AWS Certified Developer – Associate certification.

I have hands-on experience building backend and serverless applications on AWS, as well as developing web applications using modern development practices. I enjoy working on backend logic, cloud architectures and automation-oriented solutions.

I am a fast learner, adaptable to new technical environments and comfortable working in team-based projects. I am looking for a junior position where I can continue growing as a developer, contribute to real-world projects and add value through automation, cloud technologies and continuous improvement.
