Backend Developer · SAP Business One Ecosystem

I build the layer where SAP Business One meets everything else — integration servers, add-ons, and the database underneath.

Six years of development experience, reached from the business side: Business Administration at UEL and an MBA in Project Management at FGV, before formalizing the technical side with Systems Analysis at FATEC. That path is the reason I tend to ask why a process exists before writing the code that automates it.

• Integration services — Node.js APIs (Express, Fastify) talking to the SAP B1 Service Layer over OData v3 and v4
• Add-ons — C# / .NET applications attached to the SAP B1 client through the DI and UI APIs
• Data — Queries, stored procedures, and performance work on SAP HANA and Microsoft SQL Server
• Developer tooling — Internal tools that shorten the loop between a question and an answer

ai-memory-system — Persistent, cross-project memory for Claude Code, shared with Codex. Markdown files plus a few hooks: context loads automatically at session start, and search reaches across every project. No database, no service, no vendor.

b1-mcp-server — A Model Context Protocol server that connects AI development tools directly to SAP HANA / SQL Server and the SAP B1 Service Layer, behind read-only guardrails. It turns database investigation from a manual chore into a conversation.

• 80% reduction in time on the BEAS product configurator for an industrial client — a rework of the platform's slowest path, not a hardware upgrade.
• Designed and shipped b1-mcp-server, now part of the day-to-day debugging workflow.
