At Remsoft, I led the migration of the Alianças partner-integration API to asynchronous processing; it now serves 6+ companies across 8+ integrations. I also reduced memory usage by 83% and response time by 50% for payloads up to 20 MB by streaming data in fixed-size chunks.

I established a spec-driven Claude Code workflow adopted across four repositories, and shipped MCP server tools that help clients and support staff diagnose failed requests. In 2025, I built a React and Node.js Kanban board used as a CRM by 800+ people, with real-time collaborative editing.
