• Integrations with Anthropic and OpenAI APIs including tool use and function calling.
• Internal tools that reduce manual hours across our design and development production process.
• Automation pipelines connecting WordPress, Figma, Google Workspace and our internal CMS.
• MCP server integrations as part of our broader AI stack.
