About Me

My customers hire me to reach bigger online goals. E-commerce runs uninterrupted, incidents are rare, and I write documentation and tests to keep it that way. I specialize in creating mission-critical applications, such as global e-commerce systems, online streaming storytelling, and cutting-edge websites.

I founded Space Babies in 2000 and have used almost every web technology imaginable. My products routinely handle millions of visitors and are designed to be fast and reliable. I usually handle monitoring and preemptive maintenance as well.

Last but not least, I am recognised being in the top 5% of global Ruby developers on StackOverflow.

Experience

I can work solo or as team lead/manager. I am an expert in development, security, standards, and operations. I am very experienced building e-commerce systems and custom content management solutions. I enjoy increasing my customer’s value. A full stack developer such as me can complete all aspects of a website: front-end (what you see), back-end (how it works) and operational management.
