Played a crucial role in the design and development of key components of a product that boosted sales for 100+ companies by empowering 100k marketing representatives with personalized suggestions for customer interactions.My primary focus revolved around microservices architecture, where I led efforts in developing, designing, orchestrating, and deploying services to AWS Lambda, ensuring seamless scalability and cost optimization. With Java Spring Boot, I developed REST APIs and backend modules, leveraging JPA for ORM implementation, guaranteeing smooth database interactions. By introducing Docker-based CI/CD pipelines, I streamlined build processes, yielding a notable 30-40% reduction in overall build time, while maximizing agent utilization across various builds. Furthermore, I provided critical support by delivering effective hotfixes for production issues and facilitated the product support team with Python and SQL scripts for analyzing client configurations and data in the production environment.

Developed RESTful APIs using Java Spring Boot and created robust relational database schemas, RLS policies, functions, and procedures in PostgreSQL. Employing appropriate design patterns and adhering to best practices, I engineered backend modules that achieved a notable 40% performance improvement in certain system modules. Moreover, I played a pivotal role in enhancing the user experience of our SAAS application by crafting Single Page Application (SPA) UI components with Angular. I rigorously ensured the robustness and reliability of our systems by authoring comprehensive unit and integration tests using the JUnit and Jasmine frameworks, maintaining a code coverage of over 90%. Collaborating seamlessly with cross-functional teams, I orchestrated the deployment and integration of diverse modules, taking ownership of critical features from a release standpoint, and ensured timely delivery, thus significantly contributing to the overall success of the product.
