“As the Senior Software Engineer at JSGuru I was Stefan’s direct team-leader and his mentor. We worked closely on several projects and I enjoyed watching him grow into a great developer that any team would be lucky to have! Stefan’s curiosity and knowledge of web and mobile development is a huge advantage to any development process. He also completed his tasks with minimal supervision, that’s why I was confident in giving he more significant projects to handle. He’s a fun guy that had a great relationship with everyone he came into contact, that's why I believe he'd be a great fit in any team. I strongly recommend Stefan for both his technical skills as well as his communication and team work.”
