What a journey it's been! From my beginnings in hospitality and retail, through a creative phase as a baker, and then dedicating 13 years to education and the Montessori Method (including a Master's in Math Ed and nearly a MACTE certification!), I've always followed my curiosity.

Now, I'm thrilled to be starting a new chapter in tech! It wasn't the most conventional path, but I'm proof that it's never too late to pivot and pursue something new.
