Hello, World!

Hey Friend! Welcome to my corner of the internet.

I’m Teja, a Computer Science graduate from Jawaharlal Nehru University, New Delhi, India. My journey so far has been a blend of curiosity, cold coffee, and a fascination for how technology shapes our world - especially in the field of cybersecurity.

Over the years, I’ve explored everything from Software Development to AI and Cloud Computing. During my time as a Research Assistant at the SC&SS Lab, I was introduced to Transformer-based AI. This experience taught me not just the technical aspects of deep learning but also how impactful technology can be when applied to real-world problems.

As someone deeply intrigued by the rising threats in cyberspace, I’ve been honing my skills with tools like Burp Suite, Nmap Scanner, and Metasploit, while also developing secure software applications. My goal? To fuse my software development and AI expertise to tackle the cybersecurity challenges of tomorrow.

When I’m not debugging code or diving into the latest cybersecurity trends, you’ll find me brainstorming over a cup of cold coffee or recording my thoughts for my ColdCofy Podcast

Currently a Red Teamer! Wannabe Blue Teamer.

Take a look around, and if my journey resonates with you, let’s connect on LinkedIn. Who knows? We might just end up working on something exciting together!
