One of the most challenging projects I worked on was developing a scalable e-commerce platform. It was about an online store that had immediate success but without solid infrastructure. Hence the deadline was as soon as possible. We managed to finish it in a month and it was working properly. In the following three months, we made more adjustments to the system and in the end, it was running perfectly in the end. From technical aspects, we used technologies like Docker and Kubernetes to deploy microservices that communicate continuously.
