Senior Full-Stack Engineer with 13+ years of experience building scalable web applications — primarily with Laravel / PHP on the backend and React / Next.js / TypeScript on the frontend.
I design systems around Clean Architecture and Domain-Driven Design, and I enjoy owning products end to end: from discovery and scope definition to architecture, delivery and production. Previously Technical Lead at Bikeflip, an Italian bicycle marketplace. Today I work as an independent engineer through nullio.xyz, mostly with startups and European clients.
I believe technology is a powerful tool for social impact, supporting a free, accessible, and open internet.
B2B hospitality exchange platform — hospitality businesses list their structures and exchange stays with each other through a points-based system (ExchangePoints) instead of money.
End-to-end build: discovery, scope negotiation, architecture, backend and frontend.
Stack
- Backend: Laravel 11 · PHP 8.3 — REST API
- Frontend: Next.js · TypeScript · React
- Two independent repositories (API + web app)
Architecture & approach
- Clean Architecture + DDD: business rules live in the domain layer, isolated from the framework, HTTP and persistence
- Code organised by bounded contexts: Structures, Exchanges, ExchangePoints, Notifications, Identity
- Use cases (application services) orchestrate each business operation; controllers stay thin
- Domain events drive side effects (notifications, emails) without coupling modules
- Scheduled daily jobs for time-based business rules (expirations, reminders, status transitions)
- Phased delivery by milestones, with a formal change-request process to protect scope
- AI-assisted development with documented conventions (
CLAUDE.md,AGENTS.md) and phased implementation plans per repository
