- 🏗️ I design and build web applications end-to-end: architecture, backend, frontend, deployment and maintenance.
- 🏢 Multi-tenant SaaS with database-per-tenant isolation, custom auth guards and GDPR-grade handling of health data (encryption at rest + searchable hashes).
- 🏥 Real-world experience in healthcare apps (clinical records, traceability, invoicing) and travel apps (bookings, itineraries, tour operations).
- 📦 Open source package author for the Laravel ecosystem — polymorphic addresses, payment gateways, PDF rendering, page builders.
- 🔌 Production integrations with Microsoft Graph (calendar, mail, SharePoint) and custom MCP servers for AI-assisted workflows.
- 🎮 Real-time WebGL / Three.js work: physics simulation, procedural audio and interactive 3D as a way to keep the fundamentals sharp.
- ⚡ Focused on maintainable code, fast UX and automation that gives hours back to the team.
