Freelancer profile translated to English.

Description

My understanding of business processes leads me to look for the best solution for a company. With a great technical solution, you might excite engineers and developers, but if it doesn't increase revenue or, even better, profit, I've missed my goal.

I am a problem solver, and I continuously learn. Every day.

My breadth of experience over 15 years in software development, design of complex systems, and leadership of people enables me to solve a wide range of problems in companies. The more skills I learn, the better I solve problems.

"Solving complex problems through simple solutions" is the ultimate discipline. Through ever-new insights, I get better at finding simpler solutions.
