## Positioning

mazzotta.dev is Roberto Mazzotta's personal site: his professional face and a
trust proof. It builds credibility and points to Wealthior Labs, where the
offer, packages, pricing and contact live. The site itself does not sell.

**Target audience:** Swiss SMEs (KMU), 5 to 100 employees, any industry. Not
startups, scale-ups, founders or "teams that ship". Banking, insurance and
public-sector work is a quality proof from his past, not the target audience.

production engineering experience. He is the founder of Wealthior Labs, the

SMEs, not just in the demo. Clients talk directly to the person who builds, no
agency layer. Code is built with the care he learned in banking, insurance and

## FAQ

**Who does Roberto Mazzotta work with?**
Swiss SMEs from 5 to 100 people, across every industry.

**Is Roberto Mazzotta available for new projects?**
Yes. Remote mandates via Wealthior Labs.

**How do pricing and packages work?**
Offer, packages and pricing run through Wealthior Labs. After a short scoping
call you get a clear, fixed-price quote. No obligation.

**Do you sign NDAs?**
Yes, standard mutual NDAs before any sensitive discussion.

**Who owns the code at the end?**
Customer. Full IP transfer on final payment. No vendor lock-in.

**Claude or OpenAI - which do you recommend?**
Depends on use case. Claude for long-context, complex reasoning, tool use, and
Swiss / EU data residency. OpenAI for broadest ecosystem and some speech /
vision tasks. Roberto regularly builds with both.

**Can you build a custom MCP server?**
Yes, in TypeScript (official MCP SDK) or Python (FastMCP). Common use cases:
internal tool access for Claude Code and Claude Desktop, multi-tenant
connectors, database bridges.

**Do you fine-tune models?**
For most business use cases fine-tuning is the wrong answer. RAG plus good
prompting plus small focused evals wins 90% of the time at a fraction of the
cost. When fine-tuning is genuinely needed Roberto handles that too.

**How fast can a POC be delivered?**
An AI Sprint delivers a working POC in 1 to 2 weeks. Typical scope: Claude /
OpenAI integration into your existing product, a RAG proof of concept over your
docs, or an MCP server for one internal tool.

**Where are you based?**
Cham, Zug, Switzerland. Remote with clients worldwide. Occasional travel for
kick-off meetings in CH and EU.
