Full-stack engineer · Author · Founder
Eli Elad Elrom
I build software — for other people's companies, and now for my own. Fifteen-plus years shipping for teams ranging from HBO and AT&T to early-stage startups, seven technical books on React, D3.js, and blockchain, and a growing list of products I'm building and running myself.
Working remotely with teams worldwide, not tied to any one city. Outside of code: a PADI diving instructor and a licensed pilot.

What people say
From people I've worked with over the years.
“Eli and I have collaborated on many projects, including streaming video at NBC Universal, contract work for startups, and, most recently, when I hired him for a greenfield project in the insurance industry. Eli played a crucial role in setting up development frameworks (Next.js/NestJS), CI/CD pipeline, and production configuration on AWS. His work ethic is top notch and he makes good on any commitment he undertakes.”

Kevin Maes
Creative technologist & software engineering leader
