Petra PMR is a full-stack platform I rebuilt from scratch after inheriting an outdated .NET + Angular dinosaur that was slow, buggy, and impossible to maintain.

I re-engineered the entire system on Laravel 10, MySQL, and Vue.js, creating a multi-language, multi-currency environment for searching and valuing catalytic converters based on live metal prices.

The system automatically updates converter values through Metals API integration — fetching and recalculating prices for rhodium, platinum, palladium, gold, zinc, and other precious metals daily.

Key features:

• 🔐 Multi-role architecture (Admin, Maker, Manufacturer, Analyst, User) with fine-grained permissions.
• 🌍 Multi-language interface (English, Arabic, Russian).
• 💰 Dynamic currency conversion and instant price recalculation.
• 📱 REST APIs for Android + IOS application integration.
• ✉️ Automated multilingual emails and WhatsApp onboarding messages per user’s selected language.
• 📊 Admin dashboard for converter analytics, manufacturer statistics, and metal trends.

When I took over, the system was a broken .NET/Angular mess — no structure, no scalability.
I rebuilt everything: database design, APIs, authentication, background jobs, and automated notifications.
I didn’t just fix it — I owned it.

Now Petra PMR runs 24/7 with zero downtime, thousands of live converters, and growing international users.
