ABOUT ME

Experienced Full-Stack Web Developer

I'm a Senior Full Stack Developer with 15+ years of experience using technologies such as Node.js, PHP/MySQL, and NoSQL. I am detail-oriented, thorough, and passionate about clean, efficient code, and using it to solve interesting and useful problems. I pick up new technologies quickly, starting from when I taught myself QBasic and C++ at the age of 13.
