01.ABOUT ME

Ibuildwebproductsendtoendandleavethecodebasebetterforwhoevertouchesitnext.

I'm Rami, a software engineer in Hamburg with 6+ years of building and modernizing production software. I work across the full stack and don't define myself by one framework or language. What I care about is understanding complex systems and making technical decisions that hold up.

Today I'm at LimeSurvey, helping modernize a mature, large-scale product: designing APIs around an established PHP backend and moving the frontend from legacy jQuery to React.

Before that, I worked with international teams in Germany and the Netherlands on SaaS platforms, marketplaces, and complex web apps, including Overnights, Foodeli, and PeopleOverPaper. I owned core parts of those systems, not just features: architecture, APIs, authentication and authorization, analytics, and frontend.

I started out building games, more than 30 of them educational games that teach programming, and I hold a B.S. in Computer Science from Ain Shams University.

How I work

Own it end to end

From schema and API to the UI, and the production issue after launch. I stay with a feature until it works for real users.

Leave it better

Modernization, TypeScript, frontend standards, and tests, so the next change is cheaper than the last one.

Raise the team

Mentoring, onboarding, shared standards, and frontend technical interviews.
