Career Experience

I am a Chemical Engineer with experience tutoring high school and college students in chemistry, physics, and mathematics. I’ve worked both independently and through academic institutions, helping students understand complex concepts in a clear and supportive way. My background in laboratory work and scientific research helps me connect academic topics to real-world applications. I am fluent in English and Spanish, and I’m passionate about education and helping students build confidence and succeed academically.

I Love Tutoring Because

I know what it’s like to struggle with studying—especially in STEM subjects. I’ve been there, and through my own journey I learned the right strategies to overcome those challenges. Now, I enjoy guiding students through similar paths, helping them gain confidence, clarity, and real understanding. It’s very fulfilling to show them that with the right tools and support, they can succeed too.
