MotivationMotivated by the desire to create, I have found a passion for software development as I'm all thumbs and am unable to properly create things using traditional methods.ExperienceHolding a Master's Degree in Computer Science from Bremen during 2010-2015, I worked as a PHP developer while simultaneously undertaking projects to expand my knowledge in various languages like Python, Java, Javascript and C# which helped me understand language-agnostic concepts.Professional JourneyWith 7 years of practical experience as a senior full-stack developer, I transitioned professionally to become an app developer in 2019. A year prior, I founded a startup where I developed natively using Java, Swift and Flutter, while the backend API still runs on Python. As a side venture, I also founded a successful software agency with a friend in 2021, in addition to my primary occupation. Through this venture, a handful of apps created by us are now available on the iOS and Android app stores.Passion ProjectsIn addition to my primary occupation and the software agency, I run a Flutter blog that has a sizeable and growing audience, currently attracting 15,000 visitors per month.Every now and then I start projects to open up new fields in software development that I haven't tackled before. This includes, for example, game development or AI development.
