Transformational Leadership

At EXPRESS, Sree has been instrumental in transitioning the company from a monolithic ATG full-stack development environment to a composable commerce solution using commercetools. This shift has allowed EXPRESS to take advantage of cloud elasticity, improve availability and stability, and focus more on feature delivery rather than operations.1

Sree's leadership has enabled EXPRESS to deploy features faster and with more confidence, as the microservices-based architecture restricts the impact radius of changes, enhancing overall system reliability.1
