I help businesses build and improve SaaS products, connect business systems, and turn operational problems into reliable software. I combine hands-on PHP/Laravel and React development with product discovery, architecture and technical leadership. Whether you need a new feature, a third-party integration or help modernizing an existing application, I can work from requirements through implementation, testing, release and production troubleshooting. What I can help you with: - PHP 8 and Laravel backend development, plus React/TypeScript, Livewire, Alpine.js and Tailwind CSS interfaces. - Multi-tenant SaaS architecture, data modelling, authentication, API security. - REST APIs, OpenAPI, OAuth2/JWT, webhooks, Stripe checkout and provider integrations. - Background jobs, message queues, SQL optimization, caching and production debugging. - AI integrations, n8n workflows, specialized agents and retrieval-augmented generation (RAG). - Maintainable architecture using DDD/SOLID, PHPUnit, code reviews, Docker and CI/CD. Examples of my work: - Led development of PHP/Laravel platforms and APIs serving thousands of users across Europe; introduced Docker and CI/CD practices that reduced deployment time by 40%. - Co-created a cloud VoIP product using Asterisk, PHP and MySQL that reached 1,500+ extensions in its first three months. - Designed a production email notification system with a common provider interface and SMTP connectors. When the client changed providers, I integrated the replacement in hours without changing the core business logic. - Built ERP analytics for more than 50 retail stores across six states, reducing decision time by more than 50%. I own Infinita and am developing Agenda Infinita, a multi-tenant medical appointment SaaS using PostgreSQL and pgvector. Its AI-assisted multichannel messaging, WhatsApp template visual editor and MCP booking integration are in development. I am also a certified Meta WhatsApp Tech Partner. I use Codex and GitHub Copilot throughout SaaS and web development, with code review and testing. I remain responsible for the design, implementation and quality of the work. Based in Italy. English C1, Italian full professional proficiency and native Portuguese. Tell me about your product, the problem you want to solve and what a successful outcome would look like.
