Technologies
Intro Statement
I grew up with a fascination for computers and received a free hand in all the operating systems in my youth. From Amiga OS, to the various iterations of windows, to SUSE Linux, I was allowed to do whatever I pleased with the computers I sat behind on the condition that if I break it, I'd fix it. This has eventually lead me onto an autodidactic path, with coding in various languages for whatever project I fancied. It was always my view a hobby and not a career opportunity until the last few years when I had discovered that the skills I had so far only assumed to be at hobby level were comparable to business level.
I love tackling challenges, figuring out how to couple one thing to another. Learning new ways and mastering new technologies to achieve the goal I wish to reach. I enjoy helping others and sharing knowledge freely, but not at the cost of tedious repetition. I enjoy learning and to better myself with the knowledge imparted by others.
I have no formal education in programming or computer science, but I have years of experience, and I'm looking forward to a new challenge in order to better myself in what I have a passion for.

Company Owner
Dibbets Digitale Diensten
After I had moved across the country and left behind a job in a computer repair center I started my own company, where I sold computer hardware and performed repairs for consumers, and website building and maintenance for several businesses.
One of the more challenging projects I undertook was the website for PIM online. An old website had to be upgraded with a new template with a theme designed by an external design bureau. This all had to be coded in a custom port of velocity with barely any coherent documentation. By extensively studying the existing code base I was able to implement the template with a functioning website as per commission.
When the financial crisis hit money got really tight due to the lacking of commissions to fulfill in my area. My strong point isn't sales but coding, and to be able to support my family, I halted my business and went into the job circuit to have a stable income.
It was through my own company I discovered my own potential as a coder in the job circuit and was able to get the first real measure of my capabilities compared to others.

Education
Bedrijfsadministratie Niveau 4 (MBO sector economie)
Graafschap College, Doetinchem
This is where I discovered the magic of programming in VBA for access and Excel and coding my first few hobby sites, even though my education was in Business Administration but the resources offered gave me the chance to expand my skills further even though I never considered pursuing a career at that time because I only saw coding as a hobby.

Certifications
Leadership and Management
Scouts Australia Institute of Training, Chatswood
I followed this study as part of attaining the gillwell woggle to be a leader for the local Scouting group.
This was the first year where Scouting Australia was certified as a educational organisation, adding value to their inhouse training.
I passed the training at all required elements, verified by an accessor.
I however, never received the diploma and certifications. After many inqueries and being stonewalled with changing excuses, it came out that
the reason why they stonewalled me was, because I completed the study in Australia with a travel and work visum, and not a student visum, putting
Scouting Australia in a very difficult position if they were to award me the papers, possibly losing their training certification.
I decided to let it rest at that, I do have a document from the local scout leader at the time attesting to the fact that I have passed
all requirements for these certifications verified by an official certified accessor, and can happily put you in contact with her on request.
