A significant part of my responsibilities involved the evolution of our technical architecture. We transitioned from a simple, straightforward LAMP stack to a modern, cloud-based design under my leadership. Our new design incorporated Kubernetes and Node.js microservices, which were deployed on Google Cloud Platform through robust CI/CD pipelines. The tools we leveraged during this process included GitHub Actions, Terraform, Sonarqube, Jest, among others. This transformation greatly improved our scalability and flexibility, equipping us for the rapid growth we experienced.

My primary responsibility was to bridge the gap between the technical aspects of our products or solutions and the business needs of the customers. I took pride in developing complex Proof of Concepts (POCs) to demonstrate the capabilities and value of our solutions in real-world scenarios. This involved working closely with clients to understand their use cases, configuring and customizing our products to meet their specific requirements, and guiding them through the evaluation process.
