About Zakaria
I build production AI and automation systems end-to-end — RAG-grounded apps, LLM-orchestrated workflows, payment + CRM + messaging pipelines, and Claude / OpenAI / Gemini agents wired into customer-facing products.
Over the last two years I've shipped 12+ production projects solo for French and international clients: a real-time call-center + CRM dashboard for a Paris EdTech SaaS (Ringover ↔ Supabase ↔ Zoho with five n8n workflows handling 800+ daily executions), a production LMS with Stripe checkout / 2FA / OAuth / PDF certificates / 200 Jest tests / Playwright E2E, a multi-vendor marketplace with dual Stripe + Chargily checkout and Flutter mobile, an Algerian corporate film festival platform with webhook-driven payment reconciliation, and bilingual WooCommerce storefronts hardened for production.
What I deliver:
• LLM features that actually ship — Claude / OpenAI / Gemini APIs, RAG pipelines with eval gates, prompt engineering, observability. Not demos.
• Fullstack apps on Next.js + Supabase + TypeScript — auth, RLS, payments (Stripe, Chargily), real-time data, file storage, PDF generation.
• Automation backbones — n8n workflows with retry queues, dead-letter tables, signature-verified webhooks, multi-system reconciliation.
• Integration work — CRM / payments / telephony / email APIs wired cleanly (Zoho, Ringover, Stripe, Chargily, HubSpot REST, GoHighLevel REST, Mailpoet, Brevo, Sentry).
How I work:
• Solo operator. No PM layer between me and you. Direct comms with founders / owners.
• Ship-it discipline — real tests, CI/CD gates, signature-verified webhooks, idempotency keys, dead-letter queues from day one.
• Production-hardened — I optimize for "lasts without babysitting it." Caught a €3K/month silent timezone bug at a Paris client during a routine KPI-email audit.
• 1-hour average response time.
