Web Development • Freelancing • Previously

I've often done freelance work to develop and build progressive web applications and websites for clients through the years. Taking on side projects has enabled me to further build upon my technical skills, as well as providing an avenue for me to experiment with new technologies.

Most, if not all my work has been hosted on my own personal server and I frequently aim to improve on my work. Documentation can also be found on my website and Github.
