About

About Me

I'm a Software Engineer currently at HashedIn by Deloitte, where I work on AI systems, data pipelines, and backend infrastructure.

Always have had an immense interest in electronic devices and computers with a knack to learn about systems from the first principles. I love to engineer and reverse engineer stuffs like software and hardware, sometimes as a part of my work and sometimes as a hobby. This is the reason I have opted for software engineering as a career.
