After graduating from university, I started my life as a developer with an internship here. I had achieved
a lot of growth in a well-rounded and organized company.
After working as a general developer for 2 years, I became the team leader of a small team & system
architector.
I thought it would be easy from the point of view of a general developer.
However, system design seems easy, but there are many challenges. I never felt it was easy.
I have experienced a lot of stacks/skills and development of various types of projects and this has enabled
me to do valuable work for many clients after I quit my job due to covid.
