Principal Software Engineer at Xata, the serverless Postgres platform.

• Lead TypeScript technical decisions and design cross-team features with the backend team.
• Build the platform's authentication and authorization: sessions, role-based access control and fine-grained API key permissions.
• Build the platform's AI features, from agents that work on a database to the tooling that lets them reach it safely.

Earlier at Xata: main developer of the TypeScript SDK, the in-browser playground, Xata Workers and the CLI, and built an edge query endpoint on Cloudflare that caches and routes global requests to cut latency.

Agents usually get a superuser connection string. PgBeam gives them a scoped one instead: read-only access, table allowlists, PII masking and a full audit trail, all enforced in the wire protocol rather than in the prompt.
