Freelancing Software Developer (mainly iOS) with 10+ years experience in mobile iOS development and 20+ years experience in server-site software development, operations, systems architect and technical project management.
Profound knowledge in development, conception, architecture and going-live with mobile iOS App.
I have known information technology project business for many years as an IT consultant, system analyst, mobile app creator and Java expert. I have been responsibly involved in the development of innovative IT solutions of well-known companies. My experience ranges from conception and implementation as far as support and tuning of intensively visited internet applications. Besides software development, my main focuses are communication and coordination among customers, development team, hosting companies and other technical associates. Due to my work experience I had an excellent knowledge of CoreMedia's Content Management System (until 2015). Since 2009 I mainly develop iOS Apps, but I am always looking left and right.
I have worked for startups as well as for corporations. I have experienced agile transitions in companies multiple times. Since 2013 most of my projects follow the Scrum project management method (some followed Kanban).
