Introduction

Welcome! 👋 I'm @methdev, aka Crystal.

I'm a computer science graduate and full-stack software engineer, with a focus on both mobile and web development. I wholeheartedly enjoy crafting intuitive and accessible tech tools — it's like piecing together a puzzle for the digital world.

When I'm not busy coding, you can find me immersed in a book, scribbling away thoughts/opinions on the most random topics in tech and beyond, unwinding with some music, or spending quality time with friends/family and their delightful furry friends. I'm all about breaking down barriers in tech, making it fun and approachable. I believe in the power of technology to transform lives and I'm here to share that journey, one line of code at a time. 👩🏻‍💻

I continue vacillating between being an eager student & a dedicated dev.
