About

Hi, I'm David. I'm a Software Engineer living in the Seattle area. I've worked at some of the largest tech companies in the world. I started as an intern in 2013, then became fulltime at 2014.

History

I got my start at 10 years old. Dragging around UI components in Visual Basic and making a message box appear on click. From there I learned HTML and CSS. I learned Javascript and PHP. I learned about IRC and immediately wanted to make my own IRC bot. I created an IRC chat bot from scratch using PHP. This accelerated my interest in networking and protocol communications. I wrote several chat clients, services, and chat bots (mostly unfinished). I've written games, webhosting panels, CMSs from scratch, chat bots, esports websites, admin panels, SQL database codebase contributions, operating system SDKs

Once I got into college, I started learning the proper ways to write code. Testing, and unit tests. Design docs, and UML diagrams.

My main interests are in gaming, networking protocols, and chat bots. I have interests in AI and crypto, but haven't spent a whole lot of time in that.

I'm not currently seeking employment, but if you have a role you think would be perfect for me, feel free to shoot me an email. me [at] david barajas (.) com  (no space).
