My name is Jack Joynson; I am currently a hands on Software Engineering Manager at BT. I regard myself as one of those people who always questions how and why, and strives to understand how anything and everything works. Building Lego models and model railways without manuals helped my love for understanding the world grow, and by the age of twelve I rebuilt a motocross bike from parts. It is from this that my love for understanding and learning has evolved.
I view myself as being particularly good at problem solving due to my resilience and ability to think both logically and outside of the box. My ability to communicate conceptually challenging ideas often helps when tackling tough problems.
I consider myself to be technologically minded and I have had experience in many programming languages. I believe myself to be competent with most common software packages from Microsoft Office to photo manipulation. In my spare time I enjoy training at the gym with friends, karting and taking part in social events.
