A senior full-stack or backend role, fully remote from Italy, at a well-known product company. My strongest stack is TypeScript, Node.js, React and Next.js, Ruby on Rails and PostgreSQL, and for the last year I’ve built AI developer tooling: agent pipelines, MCP servers and LLM features in production. I prefer a B2B contract through my own company. A 4-day week is a big plus.

Senior full-stack engineer: TypeScript, Ruby on Rails and AI developer tooling. 11 years. Remote from Italy (CET).
ItalyWhat I'm looking for
At Groupon, I built a pipeline that turns Jira tickets into open pull requests using Claude Code. It shipped 18 PRs in its first week, and my manager asked for it to become a company-wide service.
I also designed the pipeline’s telemetry backend and built an MCP server exposing engineering-metrics tools to AI assistants. For Groupon’s move to its in-house Vespa search engine, I owned the homepage and built the Next.js data layer for its carousels.
At tl;dv, I led the SSO and SCIM integration and redesigned calendar access by decoupling tokens. During critical incidents, I reduced the meeting error rate from around 15% to under 1%.
At iubenda, I designed and built a fault-tolerant consent store for customers’ websites, handling around a thousand requests a second with no data loss. I’ve also worked across TypeScript, Ruby on Rails, backend systems, and AI developer tooling.
