Hi, I'm Rolf, 30 years old, born in the Netherlands with a huge passion for water management. My studies have taken me to Stockholm's archipelago, Singapore's harbor, and Valencia's sunlit coastline. Now rooted in Amsterdam, I merge advanced groundwater modeling with geotechnical insights to advise on sustainable solutions. ' By day, I analyze datasets to decode hydrological patterns. By night, you might find me perfecting Pizza Calculator (hydration ratios matter as much in dough as in aquifers) or perfecting my backhand on clay courts.
Make the perfect pizza with help of the Pizza Calculator. Fill in how many pizzas you want and you get the ingredients for the perfect dough.
