About Me

main image

My career spans over a decade of transforming complex challenges into sustainable solutions. From leading engineering teams through record-breaking growth in the mortgage industry to teaching the next generation of diverse technologists at Microsoft, I've consistently focused on one thing: empowering people to achieve more together than they ever could alone.

My approach combines deep technical expertise with creative problem-solving and a commitment to social good and efficiency. Whether I'm automating processes that save millions of dollars, building high-performing teams, or mentoring early-career professionals, I'm driven by the belief that technology should serve humanity—not the other way around.

What makes me unique? I bring the analytical rigor of a mathematician, the creative vision of an artist, and the inspiring spirit of an educator to every leadership challenge. I've learned that the best solutions come from truly understanding the problem and strategically leveraging people—their needs, their strengths, and their potential to optimize results.
