ZAKARIA EL ARFAOUI

I’m a Senior Full-Stack & Backend Engineer with 4+ years building and scaling production systems. I bring full-stack depth across Angular, React, Node.js, and Python, with backend specialization in Django and PostgreSQL. I’ve shipped a MEAN-stack ERP platform to production and delivered semantic search and multi-tenant SaaS infrastructure end-to-end.

At OvsVoid, I architected multi-tenant backend foundations with schema-per-tenant isolation (django-tenants), tenant-aware behavior, Celery-based processing, and secure media storage. I built a semantic search engine using pgvector with best-chunk-wins scoring and background re-embedding, and integrated Google Gemini for LLM-generated opportunity breakdowns with multi-PDF context. I also implemented robust authentication and security patterns (JWT refresh rotation, Redis-based token blacklisting, hardened API protections) and automated ingestion at scheduled intervals.

Previously at Sanford Federal Africa, I led the development of an Angular SPA with modular lazy-loaded workspaces, reusable component libraries, and role-based access control enforced through both backend-like checks and UI gating. I delivered real-time notifications with Socket.IO and push via VAPID/SwPush, built QuickBooks-backed finance workflows, and created reporting/export pipelines across Excel, PDF, and CSV. I also deployed to Azure App Service, led teams using Agile (Scrum/Kanban), and developed cross-platform mobile apps with React Native and Expo.
