Back to original languageAbout Majd
I build complete and functional web platforms, from start to finish — and maintain them.
I help companies and startups launch real web products without needing to coordinate an entire team. I handle the entire cycle: design, full-stack development, AI integration, deployment, and continuous maintenance. My priority is to deliver something that truly works in production, quickly, not a mockup.
Featured Project — car365.ma car style net
I designed and developed a complete vehicle marketplace on my own, now in production. It includes:
- User accounts, profiles, and data management
- Advanced search with Meilisearch, favorites, and price alerts
- Ad posting with automatic vehicle detection by AI (vision) and description generation with LLM
- Payment system and ad monetization
- Notifications, alerts, and scheduled tasks
- Automated deployment with E2E tests and rollback
What I can do for you
- Custom web platforms and applications (marketplaces, dashboards, internal tools)
- AI integration into your product: useful chatbots, intelligent search, automation, LLM
- Implementation and configuration of CRM (HubSpot, Twenty) connected to your website
- Maintenance and evolution of existing products
