About

Surafel Sentayehu

I grew up in Addis Ababa, Ethiopia — where I discovered programming through a desktop computer as a child. That curiosity led me to graduate from Addis Ababa University with a 3.96 GPA in Computer Science, train intensively at Africa to Silicon Valley (A2SV — backed by Google), and earn recognition from a Google Staff Engineer as a "fantastic engineer and true full-stack contributor."

Today I build AI-powered products at Manifest Automation, where I've helped grow a website to 45K visitors and 1.3M+ impressions in three months. I'm also pursuing my M.Sc. in Artificial Intelligence.

Outside of code, I play the Begena — a traditional Ethiopian 10-string lyre. It keeps me grounded. I build side projects with my twin brother and love video games.

Endorsements

"

I had the pleasure of working with Surafel for just under a year at Manifest Automation, and I would absolutely work with him again without hesitation.

Surafel is a fantastic engineer and a true full-stack contributor. He consistently demonstrated a strong ability to tackle a wide range of technical problems, from backend systems to frontend work, and did so with reliability and care. What really stood out to me was his curiosity and drive to learn — he was always exploring new technologies and patterns and proactively sharing those learnings with the rest of the team.

He's extremely hardworking, dependable, and brings a great attitude to collaborative problem-solving. Any team would be lucky to have Surafel, and I'm confident he'll continue to do excellent work wherever he goes.
