Matthew Sinex
I love building software, and I care a lot about how it's built and how it feels to use.
My name is Matthew Sinex, and I'm a full stack engineer with a focus on frontend architecture and UI design. My passion is building software that is beautifully designed both in the code itself as well as in what is presented to the end user. With over a decade of experience in software development, I have honed my skills across the full stack, with a particular emphasis on creating intuitive and well-architected frontend experiences. I hope we can work together!

03About
A bit about me.
I graduated magna cum laude from Florida Gulf Coast University in 2016 with a B.S. in Software Engineering, and started my first job in the industry the week after. I've worked with some great teams since then and learned something at every one of them.
I like working across the whole stack, but the frontend is where I'm happiest. I enjoy figuring out how an app should be put together, and making sure it feels good to the people using it.
Outside of work I spend most of my time with my wife, daughter, and dog. They're the greatest family I could ask for. I'm also into video games, music, fitness, reading, and learning Japanese (日本語を勉強しています!). Every so often I build a side project for something I want in my own life.
