As a Freelance Backend Developer at Marcom Engine, I design, develop, and maintain scalable and reliable backend services using best practices for NodeJs, Python, and Microservices. 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 third-party services as needed. I am proficient in using AWS and containerization tools such as Docker and K8s to deploy and scale 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.

I am working closely with the PS FS team. Together we help the client with digital business transformation, product discovery, increasing agility and accelerating software releases. As part of the backend team, I am deeply involved in Java (Spring Boot) and Cloud-Native Architecture on Microsoft Azure.
