After helping my community for over four years as a preschool teacher and personal trainer, I discovered and honed my passion for improving the lives of others.
In 2020 I began my adventure into software development. Today, I continue to learn and push my creative limits, with a main focus on building accessible, inclusive, and enjoyable experiences.
I am always eager to work and grow with interesting people and ideas. Send me a message if you’d like to know more or connect with me!
