Computeandmore | eCommerce Website
https://computeandmore.comAn online electronics store in Thailand.
I was hired to take all the tech decisions to migrate the legacy website to React and Django. I did it entirely by myself, working directly with the client to gather requirements and create a functional design. The end result is a compliment to the client's brick-and-mortar store and online presence.
