Ivens Signorini

Senior Backend Engineer

I build backends in Go and Java, run them on Kubernetes, and write about what breaks when AI meets production.

Trading automation with an AI advisor

Signals arrive by webhook, run through user strategies and go out as orders to several brokers. A Go backend, a SvelteKit frontend, and an AI layer that has to be right before anything executes.

AI-powered interview-prep platform

A Go backend, a desktop app with a live meeting copilot, an MCP server wiring LLMs into a real workflow, and live transcription. Every decision from architecture to shipping, owned end to end.

Privorum Insights

Write-ups of what broke in production AI

Short engineering notes from building both products. A model that answered and was thrown away, monitoring that had no callers, a retry that could never run, and what was changed each time.

03 / work with me

Available for B2B projects.

I take on backend work as a contractor: a service that has to be built, a legacy system that has to be modernised without stopping, or an AI feature that has to be made reliable before it ships. Remote, based in Porto.
