Ramu Daruru

As a Senior Technical Lead, I am accountable for ensuring the delivery of the team's committed objectives for each Program Increment (PI), including coordinating with other scrum teams to resolve dependencies effectively. My role involves thorough requirement analysis and the implementation of committed features, ensuring alignment with project goals and timelines.

Possess proficiency in designing and implementing scalable and responsive RESTful and SOAP services, leveraging best practices to ensure high performance and reliability. My expertise extends to understanding SOLID principles and multithreading programming, enabling the development of robust and efficient software solutions.

In terms of architectural principles, I adeptly apply microservices architectures and micro front-end (MFEs) using front UI Frameworks like ReactJS. This approach ensures modularity, scalability, and maintainability in application development.

Furthermore, I have hands-on experience in developing, deploying, and debugging cloud-based applications following AWS best practices. I have containerized all applications and deployed them in Kubernetes (K8S) cluster environments, optimizing resource utilization and scalability.

I possess a deep understanding of application life-cycle management, demonstrating proficiency in writing applications with AWS service APIs, AWS CLI, and SDKs. I am skilled in using containers and deploying with CI/CD pipelines, ensuring seamless integration and delivery of software solutions.

Overall, I adeptly apply Lean-Agile principles, facilitating the execution and release of value through Agile Release Trains (ARTs), thereby driving continuous improvement and innovation in software development processes.
