Software Engineer and aspiring thinker
About me & Contact info
Who am I?!
My name is David Tejuosho, and I'm a Software Engineer at Microsoft in my favorite city: Seattle. Over the two months immediately following my graduation, I got to explore Utah, Colorado, New Mexico and Arizona (with some California sprinked in). Still brimming with that youthful vigor so currently locking in and grinding hard at work while spending a bit too much time with Claude Code. In my 4 years of college, I got to complete internships with Microsoft, on the Tasks Platform team, at Benchling, on the Data Input team, with Google on the Classroom Assignment Workflow team, and at Johnson & Johnson on R&D's intelligent automation team. I fancy myself to be an idea guy but won't hesitate to jump on a team with a remarkable idea. When I'm not at work, I'm probably at the climbing gym, on a trail somewhere in the Cascades, or planning my next backpacking trip. I also run, cycle, and cook Nigerian food when I have the time. I also watch way too much Exurb1a. Once upon a time I did a lot of writing. Working on getting back into it, so look out for the substack.
