Hi there, I'm Omar 👋

Builder • Full-stack Developer • Product-minded Problem Solver

I design and ship user-focused software end-to-end — from backend architecture and data models to responsive UI and real-world product polish.

🔭 My Current Focus

Right now my main focus is building out Friend Renter. It’s a platform that makes peer-to-peer vehicle sharing between friends possible.

I’m handling every layer of the stack:

• Server/API: Built with Express + TypeScript, powered by MongoDB, with strong validation, auth, and security best practices.
• Admin Portal: React-based dashboard for managing users, listings, bookings, and payments.
• Marketing Site: Clean, SEO-optimized Next.js site to drive growth and acquisition.
• Mobile App: A React Native app for renters and hosts to list, browse, and book on the go.

The goal is to create a smooth, secure rental experience that can scale beyond my local market.

📫 Feel free to connect with me on LinkedIn, or shoot me an email at omarzumayajr@gmail.com.
