02 / THE PERSON BEHIND THE PROJECTS
More than the code.
Meet the person.
I'm Edwin Raphael, a Computer Engineering student at Thapar Institute of Engineering & Technology, graduating in 2027.
I enjoy working across the stack, from preparing speech datasets and training models to building the APIs and interfaces that make them useful. My favorite part is getting to the bottom of a problem.
Away from the screen, you'll probably find me on a football field, out for a run, travelling somewhere new, or listening to music.

BEYOND THE KEYBOARD / FOOTBALL
A different field.
The same commitment.
Football is a big part of my life outside engineering. Balancing training, tournaments, academics, and projects has taught me consistency, teamwork, and how to keep going under pressure.
