About Me

Sibi

Final-Year Computer Science Undergraduate

Specialising in Machine Learning and Artificial Intelligence

I build Tech Solutions with the aim of making a difference in people's lives. My passion lies at the intersection of AI innovation and practical problem-solving.

Machine Learning Data Engineering AI Solutions

My Journey

Diverse Experience

From Hackathons to Healthcare Ops and Tech Consulting, I've explored various domains to broaden my perspective.

Tech for Scale

I'm drawn to technology's ability to scale impact. A well-designed system can solve problems beyond what any individual could accomplish.

Why ML?

Machine Learning adds an element of bio-mimicry to my work, creating systems that evolve and learn like humans do.

Domain Experience

GenAI R&D

Enterprise AI Systems

Telehealth

Medical Crisis Response

International Affairs

Whatever the challenge, I bring curiosity, ownership, and a drive to build technology that
actually helps people.
