Obaida.

Full Stack Developer & DevOps Engineer. I build the app, the API and the server it runs on.

Five years shipping production systems end to end: Laravel backends, native Android apps, React storefronts, and the Docker, CI/CD, Redis and WebSocket infrastructure behind them. Most of what I build is still running today.

Featured work

Platforms I designed, built and keep online

Each one covers the full stack: data model, API, admin panel, client app, deployment and monitoring.

LIVEWeb + Android · Full stack & DevOps

Daily Offer

A multivendor marketplace where independent sellers run their own shops inside one store. Buyers browse every shop in one place, and vendors see orders the moment they land.

What I built

  • Vendor onboarding, per-shop catalogues, orders and payouts
  • Real-time order events with Laravel Reverb and Redis queues
  • Kotlin Android app on the same API
  • CI/CD deploys to a hardened VPS

Business Inventory

One system for a business that sells both online and from a physical shop. Stock, sales, expenses and cash all stay in one place, so the owner always knows what is left.

What I built

  • Shared stock across online orders and counter sales
  • Purchase, sales and stock-movement records
  • Expense tracking and a running cash ledger
  • Filament admin with role-based access

  • Staff roles and shop-level settings
  • Filament v4 back office on Laravel

  • Queue workers and cron jobs for async work
