  • Build Scalable Integrations: Design and implement secure, scalable APIs and integrations with third-party systems (e.g., ERPs, PIMs, customer platforms) to ensure a seamless flow of data.

  • Ship features end-to-end: From initial prototype to production deployment using AWS CDK/CloudFormation and GitHub Actions

  • Ensure Scalability and Performance: Take ownership of the backend architecture, ensuring our AI applications remain performant and secure as data volumes and user numbers grow.
