Seven years on B2B SaaS, four of them on a platform of microservices serving brands and creators. I build accessible interfaces and the design systems behind them — Vue, React, TypeScript, WCAG 2.1 AA — and I ship across Node, Go, GraphQL and Kubernetes.
I work with LLMs and AI agents in production: Claude agentic pipelines, MCP servers and skills.
I give the model the context, the patterns and the constraints, and I take the technical decisions myself. How I work with AI.

Italian and Argentine citizen. Six years working fully distributed across ten countries, with teams spanning up to nine hours of time-zone difference.
Development transcripts, scrubbed of secrets and personal data, read by Claude into typed findings. The confident ones arrive as pre-filled tickets.
A tool that reads engineers' transcripts has two ways to fail. It can send something it should never have sent, or it can produce findings nobody acts on. The second one kills it quietly.
Thirty-plus components published as an npm library and adopted as mandatory across an engineering organization of several teams.
A component library is not hard because components are hard. It is hard because every team wants a slightly different one, and every exception you grant is a bug you will ship in someone else's product.
An OpenID Connect server with an RFC 8693 token exchange, three resource servers, a client behind a backend-for-frontend, and an MCP server for agents.
A person consents once, broadly. Every token after that has to be narrowed by intersection before it touches an API, and no exchange may ever widen one.
An MCP server in front of id, inventory and social. The user asks in a chat box, and the server mints one token per audience and calls each API as them.
A chat box beats a user interface for anything you can say in one sentence — but only if the agent can reach several APIs on the user's own authority, without ever holding their credentials.
An influencer marketing platform built as a cluster of microservices and applications, serving brands and content creators. Four team rotations over four years: feature delivery, design system, platform modernization and developer experience.
A multitenant hybrid-work platform where employees pick an office and book a workspace in it.
Web3D, a multitenant platform for showcasing and selling real estate.
An agency building a marketing site and an administrative dashboard.
