About Me

Graduated with a Bachelor's in Computer Engineering, I started my career in software engineering in 2014 after discovering a love for coding and creating products for consumers. In the early days of my career, I was a fullstack engineer with a strong hands-on involvement in mobile application development before turning my attention into being a full-fledged mobile development engineer. In 2022, I graduated with a Masters of Computer Science awarded by Georgia Institute of Technology. For the next chapter in my career, I would love to be able to dip my feet into mobile fullstack engineering to gain experience in tech stacks outside of native mobile development.
