Fons Hettema

Hello there! My name is Fons Hettema. I am a freelance front-end focused web developer, and I'm very passionate and dedicated to my work.

As an IT consultant, I have assisted companies throughout the Netherlands and beyond for many years with development and advice in the field of web (applications). In 2022, I decided to start my own business after gaining valuable experience through a secondment agency, working with notable clients such as KPN, NPO, GrandVision, KoningsdagThuis, Robeco, Sky, the Gemeente Amsterdam, and Zoover & Vakanties.nl. Clients generally perceive me as a reliable, proactive, and ambitious individual with whom collaboration is seamless.

What clients and coworkers say?

I've had the pleasure of collaborating with Fons on several projects. During that time, he came across as a true team player: sociable, eager to share his knowledge, and always striving to provide feedback. We developed a strong bond during this period. I still frequently speak with him about front-end technologies and design patterns.

Tech Lead @ Empowa

I've come to know Fons as a dedicated developer with a confident and proactive attitude. He convincingly demonstrated his expertise in contemporary front-end development methodologies. He seems to have a keen sense of when to take the lead and when to simply push forward.
