I am a Morocco-based full-stack developer and currently a Senior Web Developer at Imperium Solutions. I turn product ideas and business requirements into maintainable applications, working across architecture, interfaces, APIs, data, security, testing, and deployment. I am particularly interested in SaaS and AI-assisted software development—not as a substitute for engineering judgment, but as a way to deliver focused, well-reviewed work. My priority is building coherent products that solve real operational problems.

A multi-tenant SaaS platform for Moroccan car-rental agencies.

Many local agencies still coordinate daily operations through WhatsApp, spreadsheets, paper documents, and disconnected tools. RentalOS brings cars, availability, customers, booking requests, reservations, staff, roles, contracts, commissions, booking statuses, and public agency booking pages into one operational product.

• My contribution: Product analysis, requirements, architecture, database design, full-stack implementation, security review, testing, and deployment.
• Main technologies: TypeScript, PostgreSQL, Prisma, Better Auth, and Vercel.
• Architecture highlights: Multi-tenant design, agency-level data isolation, authentication, role-based authorization, relational modelling, server-side validation, booking lifecycle management, public booking flows, and reusable components.
• Links: Portfolio and technical overview · Live product demo
• Source availability: RentalOS is an active product in development, and its full source code is not publicly available. A live demonstration and product walkthrough are available through the links above.

A second-hand fashion marketplace for Morocco, with browsing, search, cart, listing, and account experiences.

• My contribution: Full-stack storefront and customer flows.
• Main technologies: Laravel and Tailwind CSS.

Idea → Requirements → Architecture → Implementation → Review → Testing → Deployment

1. I start with the business problem: users, journeys, rules, permissions, constraints, and edge cases.
2. I use ChatGPT to challenge assumptions, identify missing cases, structure PRDs, and prepare implementation plans with clear acceptance criteria.
3. I give Codex or Pi Agent focused tasks with the relevant files, business rules, constraints, and existing codebase conventions.
4. I inspect every generated diff, run the application, and validate functionality, permissions, loading states, errors, and edge cases.
5. I refactor where needed, document important decisions, use GitHub for version control, and deploy previews and production releases through Vercel.

AI accelerates my workflow, but product decisions, architecture, security, validation, code quality, and final delivery remain my responsibility.

Currently focused on building production-ready SaaS products, refining AI-assisted engineering workflows, and delivering scalable full-stack applications with TanStack Start.
