My interests and work history have spanned a range of fields, from pharmaceutical document control to security work (both private and public) to the IT sector, although admittedly document control was never an interest. Professionally, my interests have always revolved around helping people, but also what can make for a good story, as I've always enjoyed the life stories of others and I like very much the idea of having my own to tell. In this way I like to think that I'm a good employee to have around because I like to make work enjoyable and to take opportunities which I think will be worth sharing with others. Personally, my interests are simultaneously vast and typical for someone who looks like me. I love aviation, science fiction, travel, and delving into all kinds of topics, whether it be languages, philosophy, various sciences, and surely much more. I love to write, I like to read, and I strongly enjoy the lore of all kinds of fictional universes, mostly because of how imaginative they are and I appreciate novel ideas and themes that I come across. I love humor and sharing it, although I've been told I can push the envelope a bit in that regard so I'm working on that since it's important to me that we can all share a laugh together and I strongly despise bullies. I love more than anything my wife and our young daughter. I ruminate often on the lessons I can teach her from my own life and how I can be the best father possible to her. I also hope she will enjoy video games like me, as they are a close second to her and her mother in terms of things that I love.
