I help companies build complex booking and scheduling platforms with Laravel, Livewire, and FilamentPHP while keeping their systems scalable, maintainable, and reliable under real production usage. 🚀 Projects delivered up to 30% faster 🧩 Systems made significantly cleaner and easier to scale within the first 30 days 👋 Hey! I’m a Livewire & FilamentPHP Tech Lead with 10+ years of experience building backend-heavy Laravel applications. I specialize in complex booking and operational systems where precision, performance, and maintainability matter. That includes challenges like: * Timezone-aware scheduling * Overlapping booking prevention * Resource & capacity management * Real-time availability handling * Multi-location scheduling systems * Complex operational workflows * High-volume booking architecture I don’t just build features. I help teams design systems that continue working reliably as operational complexity grows. What I specialize in: * Laravel, Livewire & FilamentPHP * Complex booking & scheduling systems * SaaS architecture & scalable backend systems * Multi-tenant platform development * Complex business logic & operational tooling * Refactoring unstable or difficult-to-maintain systems * Performance optimization & database design 🏆 Worked directly with the Creator of FilamentPHP I worked with Dan Harrin at Stagent, building production-grade systems with FilamentPHP. If you're building with Filament, I bring real production experience beyond starter kits and basic admin panels. ✅ What I help teams with * Designing scalable booking architecture * Building timezone-aware scheduling systems * Preventing scheduling conflicts and operational edge cases * Building clean admin panels & operational tooling * Turning MVPs into stable production systems * Improving maintainability and long-term scalability 💬 Why companies work with me * I identify scalability and operational risks early * I think deeply about edge cases and system reliability * I focus heavily on maintainability and backend architecture * I challenge technical decisions that create future problems * I balance fast delivery with long-term system stability 🔍 Not sure if I’m the right fit? I offer a free 1-hour working session where we can: * Review your booking architecture * Identify technical bottlenecks and edge cases * Discuss scaling and maintainability * Outline practical next steps No pressure, even if we don’t work together, you’ll leave with technical clarity and actionable direction.

I build infrastructure that stays up when it matters. Government platforms for 2M+ citizens, banking systems for 1M+ users, and AI rendering stacks on GPU Kubernetes clusters. Shipped on time, documented for the team that inherits it. 5+ years owning the full stack: physical hardware, hypervisors, Kubernetes, service mesh, cloud networking, CI/CD, observability, and GPU AI workloads.
