The Story Behind
The Engineer

My journey into technology began at the age of 9, when my father enrolled me in a computer course. That single decision changed everything. I fell in love with computers and spent every summer holiday earning certifications — from Windows and MS Office to Unix, C Programming, and eventually a Microsoft Technology Specialist credential at age 19.

I pursued a B.Tech in Information Technology from Sri Eshwar College of Engineering (2014), coming from a Bio-Maths background — an unusual path that gave me both analytical rigour and creative problem-solving instincts.

Over the past decade, I have evolved from an InDesigner and Web Designer to a Full Stack Developer, then a MERN Stack Engineer, followed by deep work as a Data Analyst and Database Engineer supporting enterprise clients across Australia and India. Today, I serve as Technical Head, leading product architecture, server management, and engineering teams.

Outside of work, I enjoy building side applications, managing science and technology content, and practising as a mid-level outline artist. I'm currently expanding into ReactJS and AI/ML because curiosity never stops.
