Background

Growing up, I was the kind of kid who constantly asked questions about how things worked, and more importantly, why they worked that way. I wasn't satisfied with simply fixing the problem — I wanted to understand what caused it in the first place. That curiosity naturally led me toward problem-solving. I enjoy breaking complex challenges into smaller questions and working through them step by step until the bigger picture becomes clear. Rather than settling for quick fixes, I prefer identifying the root cause, understanding what went wrong, and finding ways to improve it. Learning, critical thinking, and staying grounded in facts are values I carry into everything I do. I believe every challenge has a pattern, and every pattern tells a story — you just have to know where to look.
