About Me

I'm a Full Stack Engineer focused on building scalable, production-grade systems that stand the test of time.

I care deeply about clean architecture, developer experience, and shipping software that actually works at scale.

When I'm not building, I'm reading about distributed systems, contributing to open source, or exploring new technologies.

I like fast-moving teams and owning a problem from the first sketch to whatever's running in production. If you have something in mind, let's chat.

Worked with a clean Git workflow (feature branches, pull requests, code reviews) to ship features safely and keep the codebase maintainable.

The Slogan Hub

Full Stack Engineer

Oct 2024 – Oct 2025

Remote (Morocco)

Architected and developed LaundryHub, a multi-tenant SaaS Operating System designed to bridge offline laundry operations with online sales. The platform successfully manages multiple client deployments with complete data isolation, resulting in a 40% reduction in administrative overhead for vendors.

KEY ENGINEERING ACHIEVEMENTS

Robust Multi-Tenancy: Engineered a shared-infrastructure architecture using "Row-Level Isolation." Implemented global Prisma middleware to programmatically inject tenant filtering into every database query, ensuring zero cross-tenant data leakage.
Cross-Domain Handshake Protocol: Designed a secure, dual-layer API (Admin & Public Integration) to solve state-loss issues across domains caused by 3rd-party cookie deprecation. Built a token-exchange handshake allowing external WordPress sites to securely process checkouts on the SaaS domain.
Granular RBAC: Developed a role-based access control matrix (Super Admin to Delivery) enforced via NextAuth.js middleware and custom JWT claims, providing high-performance, fine-grained security without redundant database lookups.
