ABOUT ME

Software Engineer, Tech Lead & SQL Developer

I have 14 years of experience in developing software in which I have undertaken different roles - from being a database designer & SQL developer to maintaining middle layer in Java and front end in VueJS. I also lead software teams to ensure the timely release of the software. I believe that software should be designed that it is functional and usable by the end customer.
