🧠 What I Do

I'm a senior Laravel/PHP developer who takes ownership from requirements to production. I specialize in:

  • AI-augmented engineering — RAG and vector search (pgvector/Pinecone), LLM API integration, and daily agentic coding workflows
  • Backend architecture — Laravel/PHP services, RESTful APIs, MVC, clean and maintainable business logic
  • SaaS & business systems — multi-tenant/reseller platforms, e-commerce, invoicing, booking, and order management
  • Integrations — third-party APIs, payment and order workflows, data synchronization, PDF/document generation

My approach: break down complex problems, create a plan, take action, and iterate until it's done. Give me a goal — I'll handle the rest.

🛠️ Tech Stack

💡 Featured Projects & Impact

  • AI-powered e-commerce / PIM platform (PimPick) — deep multi-provider AI integration (OpenAI · Gemini · Claude · DeepSeek behind one abstraction layer). An AI Wall composes a wallpaper product into a customer's own room photo (image-to-image), plus AI catalog enrichment (descriptions/SEO/translation), AI vision (image → product data), and AI URL scraping — all async via a Node.js job queue, with an OpenCart 4 storefront and a Laravel + Vue 3/TypeScript console.
  • AI-powered verification SaaS (InsureVerify) — Google Gemini Vision reads insurance/licence documents, extracts and name-matches the details, and feeds a composite risk score (IVRI) alongside Checkr background checks. Laravel + Vue 3/TypeScript with subscription billing, a token-authenticated developer API, and real-time chat.
  • Multi-tenant AI PIM SaaS (platform-pim) — four LLM providers (OpenAI · Claude · Gemini · DeepSeek), AI vision, AI attribute/category mapping, an inline AI Copilot, and smart CSV import with AI column mapping. React 19 + Express + Prisma/PostgreSQL (87-model schema), Auth0 SSO.
  • Multi-tenant website-builder SaaS (Uvisual, Node rewrite) — a drag-and-drop visual editor with SSR multi-domain publishing, reseller management, Mollie billing, and a legacy-PHP migration pipeline. React 19 + TypeScript + Express + Prisma, Docker/Caddy deployment.
  • Luxury car-rental platform + DevOps ownership (Exotic Cars Rental) — a three-app system (Next.js 16 storefront · Vue 3 admin · Laravel API) with booking, availability, multi-currency pricing, OAuth, S3, and WhatsApp. I also owned the CI/CD pipeline and VPS server setup — GitHub Actions SSH deploys, PM2 zero-downtime reloads, on a DigitalOcean Ubuntu 24.04 droplet (Nginx + Apache reverse proxy, UFW firewall, Certbot/Let's Encrypt TLS).
  • Multi-tenant B2B reseller SaaS (FinditTrading & Compleetshop.cloud) — 19 live reseller storefronts, each provisioned dynamically with its own isolated database and custom domain/subdomain. A product-sync engine keeps ~14,000 products in sync (options, categories, images, pricing, stock) from parent to every reseller, with orders forwarded back for cost-price and margin tracking.
  • Multi-vendor travel-booking marketplace (Fyvco) — customized and extended a modular Laravel platform spanning 8 booking verticals (hotels, tours, cars, flights, boats, events, spaces, airports), with vendor payouts, six payment gateways, and multi-currency / multi-language.
  • 50+ projects delivered, 14 Upwork projects at 5★ (Top-Rated), and a 2-developer team led end-to-end through build, QA, and production support.
  • End-to-end Laravel document platform (AugmentaInvoice) — quotation → proforma → invoice → packing list → purchase-order workflows, with Excel import/export, approvals, and configurable PDF export.
  • Mapping & geolocation for rental logistics (WorkSecure) — extended a live Laravel invoice platform with unit-rental booking and a mapping layer: units and active bookings plotted on Google Maps & Leaflet with status-coded markers, address autocomplete + geocoding, and a GPS feed tracking each unit's last-known location.
  • Replaced a manual Photoshop workflow (ProfichemApps) — an in-browser drag-and-drop label/poster editor with crop, resize, layering, and PDF/PNG export.
  • Custom OpenCart e-commerce (BroditStore.nl) — a Dutch Brodit car-mount store with a vehicle/device compatibility matrix (brand · model · year), automated supplier feed sync with per-category pricing, bulk import/export, Mollie (15+ payment methods), and 39-language + GDPR support.
