Principal Cloud Solutions Engineer

As a Freelance Backend Developer at Marcom Engine, I design, develop, and maintain scalable and reliable backend services using NodeJs, Python, and Microservices best practices. I ensure high performance, availability, and security of REST API design | architecture and implement Unit Testing | End-to-End testing for code quality assurance.

I collaborate with clients to understand their requirements and integrate 3rd party services as needed. I am proficient in using AWS and containerization tools such as Docker and K8s for the deployment and scaling of applications. I create Technical Documentation to ensure easy maintenance and troubleshooting.

I utilize SonarQube, Jenkins, Nexus, and Code Coverage tools to ensure code quality and adherence to best practices. I also implement DI (Dependency Injection) to enhance the modularity and testability of my code. As a Freelance Backend Developer, I play a critical role in the success of the projects I work on and ensure the seamless integration of the backend services with the overall system architecture.

Skills/Stack: Node.js · K8s · RESTful WebServices · Unit Testing · Software Documentation · Nexus · Python (Programming Language) · Docker · Jenkins · Amazon Web Services (AWS) · Sonarqube
