Summary

I wrote my first line of code in a high school computer science class. Mostly because all of my friends were taking the class. I stayed for the thrill of solving hard problems, and building things from scratch. Now, as a Lead Developer at General Motors, I've led development across several critical applications, including a platform enhancement that contributed to $1B in annual savings. I'm a fast learner, write clean code, and I'm the person teams call when something's broken or has performance issues. I'm now looking to bring that energy to a company whose main product is software, where I can more directly shape the future of the product.
