I've been designing & developing games, applications and other software solutions since 2011. When I work on a project, I strive for excellence and 100% client satisfaction. I can understand both long-term and short-term goals, I am good at planning but I also know how to stick to a plan if one is provided. When there's time, I like engineering robust solutions that can handle the test of time (modularity, upgradability, sustainability). That doesn't mean I don't know how to develop fast and dirty when the situation demands it; ie. specific unforeseen deadlines. Though I'm a technical person I've worked successfully both for and with non-technical people so I tune conversations and reports based on who I'm talking to. I take pride in my job and I'm good at it. On the projects I've worked on, I usually end up wearing many hats. From developing games on my own, to undertaking intimidating projects with a very small team I can work efficiently in any of the following areas of expertise: game design & development, algorithm engineering, computer science R&D, software engineering and coding. The foundations of these skills come from my education, which is a Bachelor's in Computer Science & Engineering and two Master's degrees (one in Computer Science and one in Game Design) as well as my growth on top of these foundations through dedicated & passionate freelance work. Have an awesome idea or a project that's underway? Send me a message. Maybe I can help make it a reality. You can view some of my work under the Portfolio section of my profile.
