For more than 7 years I have worked as a professional software engineer.
My core expertise are customer facing web- and hybrid-mobile applications. I develop for corporate, medium-size enterprises and start-ups. I am a big fan of clean, modular and efficient code. Also, I love functional programming and prefer a declarative style of writing code.
Software development is a team sport.
I wrote my first line of code in PHP as a teenager.
My professional career I started as a Junior Developer in Billy Mobile, a cool AdTech company in Barcelona, Catalonia, Spain.
Later, I worked for many years in the W&W Interaction Solutions GmbH (formerly known as treefin GmbH) as a Full-Stack engineer in Munich, Germany.
Today, I work as the founder and Senior Software Developer of Lissner Technology Consulting, S.L. – a software engineering company.
Originally from Germany, I live with my family in the lovely Priorat wine area in Southern Catalonia, Spain.
