Experience

  • Serverless Telematics on AWS

    It has been my privilege to work on the project for Hitachi Capital UK PLC, which uses the AWS Cloud as a platform. During the project, I introduced AWS best practices, implemented security, evolved the company cloud policies, improved the team culture, and implemented a serverless architecture.

    Serverless architecture is one where the components chosen are offered as a service. This means that the service provider takes care of the underlying infrastructure, and the consumer is responsible for how the component is used. It allows a consumer to focus on business functionality without regard for the commodity compute resources that support the component.
