What Motivates Me?

10-year old David probably could not have guessed where I’d be now. I’ve made several pivots in deciding what I want in my career and I don’t imagine the changes will stop – from pre-med in college to software development in the healthcare sector as my first job out of school to engineering management now. Who knows where I’ll end up next? As long as I’m growing, I’ll be happy.


Learning to code has been an incredibly valuable skill that has opened doors for me in ways I wouldn’t have expected. Living in a digital world, it’s become more and more important understanding how things work.


Having a poor memory requires that I stay organized. My reason for loving strong organization schemes – whether it’s people organization, stuff organization, or data organization – is that it allows me to lean hard on the system and trust in its effectiveness.


Being a strong coder is only the start to developing robust applications. Learning how to do so by leveraging a group of strong developers requires a different set of skills.


“If you want to walk fast, walk alone – if you want to walk far, walk with others “ A leader that can inspire others can get more done. I strive to model myself after leaders that have come before me and have earned my respect.
