What I do

What I'm building

→ Casa Brunelli · LIVE · Custom booking platform for a Tuscan villa. Saves the owner €11–15k/yr in OTA fees.     See the case study.

→ Sevilla PMS · In build · Multi-tenant property management SaaS for the Spanish rental market. Six apartments, twenty-four tenants — real portfolio, not a demo.

→ HPS-ai-hub · In build · My personal agents workflow — SDD + multi-model routing + Engram persistent memory across multiple development domains.

How I work

I use HPS-ai-hub, my own agents workflow. Spec-Driven Development for architecture-first planning, multi-model routing (Opus / Sonnet / Haiku) for cost-aware execution, Engram for persistent memory across sessions. Runner: Claude Code / OpenCode. Migrating to Pi + gentle-pi.

Senior-architect discipline at founder-engineer speed.
