Build MCP servers and connectors for governed access to GitLab, Salesforce, Gainsight, Kantata, Thought Industries, Gong, Snowflake, and other enterprise systems
Add evaluations, tracing, and human-in-the-loop checkpoints to keep internal and customer-facing agents measurable, auditable, and safe with customer data
Evolve the CX Application Platform's gateway, AWS infrastructure including ECS, RDS, and Lambda, Terraform configuration, application scaffold, and deployment path
Own applications such as PS Compass, Congregate, and GitLab University and its integrations, documenting build-versus-buy and consolidate-or-sunset decisions
Ship production-quality Python and TypeScript through GitLab CI/CD, with tests, observability, security review, and runbooks
Design every application for handoff, with documentation, monitoring, and shared ownership
Prototype with Customer Success, Digital Success, Professional Services, Education Services, and Training in days, not quarters
