Projects

Three flagship systems, then the archive. Depth over volume.

AI Operations Platform

A production agent platform for a US professional-services firm: 60+ AI actions behind a router and a propose/confirm/execute state machine, 3-model consensus answers, a Neo4j knowledge graph, and Slack, email, and chat surfaces. Every action runs through human approval gates and lands in a full audit trail.

TypeScript · Next.js · Postgres · Claude / GPT / Gemini · Neo4j

Ostavio

A personal AI daemon for business operations. It watches email, tasks, and billing, prepares morning briefings, and proposes actions the owner approves with one tap. The same architecture as enterprise agent platforms, scaled down to a single operator.

TypeScript · Next.js · Postgres · Claude / GPT / Gemini

Eucalipse

The software agency behind the rest: 50+ projects shipped since 2019, from SaaS platforms to AI operations systems for SMBs across retail, accounting, and consulting. Architecture, hiring, and delivery under one roof.
