Open case study ↗The flagship work tells the strongest product story. These case studies and earlier projects add package design, platform thinking, and professional delivery work.
A multi-tenant portfolio publishing platform in development, with a Next.js Studio and an authoritative ASP.NET Core backend.
A role-aware enterprise operations frontend for vehicles, drivers, gates, cards, visitors and loading workflows.
Desktop invoicing and operations system with invoices, catalogue items, expenses, workers and audit history.
Arabic-first oil-remediation learning and simulation app with theoretical modules, practical calculations and saved experiment results.
