Biography & Tech Stack

I am a self taught software developer moving from a Mechanical Engineer. I started coding while I was still a MechE student. After securing my first job as a Mechanical Engineer, I realised I don't have much passion in mechanical stuff but software. I started taking online courses on frontend progamming like Flutter, HTML, CSS and Javascript.

After securing a job in tech field, I started learning backend and shift my focus towards web development which were Nodejs, Reactjs, Mongodb and MySql. This was the phase which I started transfroming myself from a Frontend Developer to a Fullstack Dev.
