01 // About Me

Who Am I?

Name Rozario Rajkumar

Date of Birth 07 October 2004

Age 21 years old

I'm a BCA Graduate, Certified Digital Marketer and Certified UI/UX Designer — worlds that most people keep separate, but I live all at once.

In tech, I build web applications and write clean code across C, C++, Java, Python and JavaScript. I love turning ideas into real products that people actually use.

In digital marketing, I understand how brands grow online — SEO, social media strategy, content creation, audience targeting and online branding. I don't just build products, I know how to get them seen.

In UI/UX design, I craft interfaces that are intuitive, visually sharp and user-first — wireframes, prototypes, design systems and experiences that feel effortless to use.

And through it all, I write music lyrics — storytelling is the thread that connects everything I do. Watch this space.

Fire in my chest like the Word pouring out

They false preach, I see snakes in the crowd

Code so cold, make the demons log out
