Lead development of the enterprise GraphQL API layer, meeting performance, scalability, and security standards. Partner with business stakeholders and technical teams to understand needs and deliver simple, effective solutions. Define and enforce API design standards, governance, and best practices. Mentor mid-level and junior developers, fostering collaboration and technical excellence.

Work with MS SQL, PostgreSQL, Oracle DB, and other data stores to ensure efficient data access and transformation. Improve developer experience so other teams can integrate with the platform easily.
