I specialize in AI Infrastructure, Developer Experience (DX), and 0-to-1 Architecture. I design systems that don't wake you up at 2am—resilient queues, clean API gateways, and observability that actually works.

Based in Porto San Giorgio, Italy (CET). Working remotely with US/UK teams since 2014. My mornings are your "while you were sleeping" deep work blocks.

I don't just use tools; I build the "paved roads" for other engineers.

I help founders and engineering leaders untangle complexity and ship faster.

• SOLVE — AI-first MVPs & Distributed Systems Design and ship RAG/agent pipelines with proper guardrails. I untangle legacy APIs and data models so your team can stop tiptoeing around them.

• OWN — End-to-End Delivery Scope → Architecture → Implementation → Infra. I build API platforms and data contracts teams can ship against, favoring simple, proven patterns over hype.

• DE-RISK — Make it Maintainable Align early, document decisions (ADRs/RFCs), and bake in CI/CD and telemetry. I leave behind clean handoffs that your team can maintain after I leave.

What founders get when they hire me as a Fractional Principal / Lead:

1. Clarity: A clear problem brief, risk list, and prioritized backlog we align on immediately.
2. Architecture: A concise design doc and a realistic delivery plan.
3. Production MVP: A functional, observable system live in 4–8 weeks.
4. Handoff: CI/CD pipelines, preview envs, and ADRs so your team can take the reins.
