Hi, I'm Mimoun Ghordou

Multi-tenant ERP-lite with point of sale for Moroccan retailers: inventory across stores and warehouses, purchases, quotes, refunds, customer credit and cheques, cached analytics and plan-based entitlements. The UI is available in Darija, Arabic, French and English with full RTL.

• Built most of the stack: Liquibase migrations, Spring services and REST APIs, the Next.js UI, and receipt and invoice printing (ESC/POS and A4)
• Tenant isolation in three layers: JWT claims, workspace-scoped repositories, PostgreSQL triggers
• 2,000+ backend tests on Testcontainers with query-count guards; OpenAPI-generated client; Cloudflare Workers deployment

Multi-tenant e-commerce operations SaaS: an isolated workspace per tenant, Stripe billing, Google OAuth, shop-builder and delivery-carrier integrations, a visual workflow builder and a UI in four languages.

• Owned the workspace and multi-tenancy model and attribute-based access control: roles, permissions, workspace access tokens
• Built the order lifecycle: status transitions, history and checks, and a workflow engine triggered on order creation
• 600+ backend tests; FloTable was extracted from this codebase

Lead-to-call scheduling tool used daily by a small sales team. Leads arrive from the website and Meta Lead Ads, schedulers book technical calls from a free-slot grid, and the least-loaded engineer is assigned automatically.

• Every rule lives in PostgreSQL: row-level security, ~50 security-definer functions, an exclusion constraint that makes double booking impossible, generic undo via a change log
• Outbox email pipeline on pg_cron and Edge Functions; PDF quotes through Cloudflare Browser Rendering
• 540 pgTAP assertions and 193 Vitest tests, written before the code

T-beam module of a structural-calculation platform for civil engineers, integrated into an existing Spring Boot and Next.js codebase. The spec existed only as Excel workbooks implementing the CNR-DT 200 FRP guideline.

• Translated the workbooks into 8 calculation services and immutable records; replaced the manual Goal Seek with a bracketed Brent root-finder; generated the DOCX calculation report
• Proved Excel parity with 44 parameterized tests and a no-mock end-to-end test pinning all 21 outputs
• Coordinated three contributors, reviewed and merged 16 PRs, and plugged into the platform's existing extension points without changing them

Declarative framework for building visual workflow editors. Nodes declared with @defineNode, @Input and @Output decorators get a React Flow editor and an async execution engine with JSON serialization.

• Owned the engine: compile-then-run execution plans, typed async events, four cancellation modes, and the control-flow nodes (if, switch, for, while, forEach) behind extensible interfaces
• 650+ Jest tests; benchmark suite guarding against regressions

Zero-dependency React table component for ERP-style screens: typed column renderers, quick filters and filter pills, controlled and request modes with server-side pagination. Used in production by TajirPro and HandOff.

Full compiler pipeline (lexer → parser → code generator) for Oracle QuickSQL, written in C. Outputs standard SQL DDL, decoupling QuickSQL from Oracle DB, and extends the language beyond Oracle's official tooling.

Blockchain-based pharmaceutical supply chain tracking. Smart contracts ensure integrity from production to consumer. Full lifecycle: analysis, technology benchmarking, UML design, implementation.
