About Me

From healthcare to tech: A journey of continuous learning and growth

My Journey into Tech

My career path is unconventional. I started in medicine as a Certified Nursing Assistant, helping patients directly in healthcare. However, I felt drawn to technology and made the leap into IT. That decision changed everything. I landed my first IT role and grew rapidly within itโ€”not because it was easy, but because I was committed to learning every aspect of the business.

Working at a growing SMB meant my role evolved alongside the company. What started as general IT support expanded to include infrastructure, system administration, networking, and ultimately cybersecurity. This organic growth exposed me to the full technology stack, teaching me how every piece connects and why security and infrastructure matter just as much as code.
