    Hi! I'm a professional full stack software engineer with ample experience in various tech companies. During my tenure in tech, I have-- Helped ultra small companies get products off the ground Worked with start-ups to scale products with demand Been an engineer in the world's largest cloud service provider--AWS. Web applications are my speciality. While working at Amazon, I helped create a brand new product which launched with the ability to scale to millions of users. I use TypeScript every day to create cloud based software, both user interfaces and scalable infrastructure. I'm comfortable across the stack, but especially enjoy building a user experience focused frontend. That being said, not every project needs to be gargantuan. I also have a passion for automation and efficiency and I love helping small businesses grow into custom software solutions. If you're just getting started and need some technical expertise, or if your business has outgrown the off-the-shelf tools that have gotten you this far, let's chat!

    Ever since I was a kid, I've always been fascinated about how computers work. This fascination led me to pursue a future in tech. I started on the hardware side but quickly realized that I was much more passionate about software. What I love most about software engineering is the type of thinking required to tackle every problem. The fact that there are many ways of solving any problem is what really drew me in. Since I've switched from hardware to software, I've learned and built projects with Ruby on Rails, React, Redux, Mongo, JavaScript, Express.js, Node.js, and PostgreSQL. I've loved learning about the differences between the frameworks and how they're used to create web applications.
