Over the years I have accumulated a specific amount of knowledge and skills, which would be a waste to have just lying around.

Started in 1998 with server/system administration, then an educational stop in VOIP and networking. I find myself in web development, including the exciting business element of it.

My core principles of working include high performance, high scalability, rapid development, mobile optimization, social functionality, search engine optimization (SEO), interactivity, navigation, analysis and reporting on every aspect, data API's and clean code.And winning teams are created when you combine all of this with the right advertising, affiliate sales and email campaigns.

At present, during working hours, I am active in the analytical world of Oracle BI @ i4bi, an OBI consultancy firm.
