AI Tooling & Developer Experience
- Packaged the Dependabot vulnerability remediation workflow into a reusable Claude slash command — adopted across all web teams, turning a multi-step manual process into a < 3-minute fix.
- Built MCP servers for both Observability & Analytics SDKs so engineers could integrate without reading docs — collapsing a doc-heavy setup into same-day adoption.
