01 · about me

Who I Am

I'm Ousama, a mobile and web developer from Beirut, Lebanon. I've spent the last five years shipping real products: a tutoring platform serving 20,000+ students, a ride-hailing and delivery ecosystem for the Lebanese market, and content apps used daily by creators.

I work across the whole stack: React Native and Flutter on the front, Firebase and Supabase behind, CI/CD and store releases to close the loop. I also tutor college students in mobile development at Warshe961, because explaining something well is the best proof you understand it.

OEG: Online Tutors & Lessons

Our Easy Game (OEG) is a private tutor in your pocket, 24/7. Students post a request and verified expert tutors bid to help with homework, exams and thesis work across 100+ subjects. I lead development across mobile and web, and executed a full migration of 20,000+ users with zero downtime and no data-integrity issues.

  • Backend integrations, authentication systems & APIs
  • Cloud infrastructure & admin dashboards
  • CI/CD workflows, testing & multi-platform releases

IYKNO: Tutors & Homework Help

Homework help from real tutors, completely AI-free. Students post a question, verified tutors reply with a price, and every delivery ships with an integrity report. I built the app in React Native from the ground up: architecture, UI/UX, real-time data and release to both stores.

  • Full product build: design to deployment
  • Real-time chat, requests & tutor bidding
  • Store-compliant release pipeline

Clip Kitchen: Video Editing

Content, served daily. Users send raw clips straight off the job, real editors turn them into finished reels, and the app publishes them to Instagram, TikTok, Facebook and YouTube. Includes a library of trending reels to copy what already works. Built in React Native with a media-heavy, fast UI and a cloud-backed pipeline from upload to approval.

  • Media-heavy UI with smooth performance
  • Cloud storage, upload & review pipeline
  • Cross-platform delivery, single codebase

SwiftGo: Food Delivery & Rides

A dynamic ride-hailing and food delivery platform tailored for the Lebanese market. I spearheaded the whole ecosystem: rider app, driver app, store panel and admin panel, with real-time tracking and localization.

  • 4-app ecosystem: rider, driver, store, admin
  • Real-time updates & localization support
  • Compliant releases on both stores
