As a freelancer, I worked on small to medium-sized projects in various domains such as marketplace, e-commerce, online reservation, and bookkeeping. I formed a team of four persons with complementary skills along the way, which I work with to this date.I mainly focused on back-end development and server-side technologies during this period. However, I undertook some full-stack roles as well. Moreover, I practiced product management, software engineering, requirement elicitation, and small-scale team management.
