Java Developer

Carson Tahoe

September 2023 - April 2024

● Developed backend functionalities using Spring Boot and Hibernate, collaborating with cross-functional teams including product managers, designers, and QA engineers to ensure technical solutions aligned with business goals and user needs.

● Spring Boot’s microservices architecture allowed for faster development, testing, and scaling of backend systems. Its powerful dependency injection and simplified configuration made it easier to maintain and extend the project, ultimately delivering a high-quality product that met both technical and business requirements.

● Spring Boot’s built-in support for components like Spring Security and Spring Data simplified the integration of authentication and data access layers.

● Automated workflows using Java-based solutions and integrated with task schedulers like Quartz to streamline operations and minimize manual intervention.

● Quartz was implemented to manage scheduled jobs, such as sending automated email notifications and executing periodic data processing tasks.

● Integrating Quartz into the system ensured that these tasks were reliably executed without manual oversight, thus improving operational efficiency and reducing human error. This automated approach also freed up team members to focus on more critical tasks, while Quartz ensured that routine processes continued without interruption.

● Implemented caching mechanisms using Redis to optimize performance, reduce load times, and ensure smoother experiences for end users.

● Redis, as an in-memory data store, was integrated to cache frequently accessed data, such as product details and user session information. This drastically reduced the time required to retrieve data, improved overall system performance, and decreased the load on the primary database.

● Redis also provided a simple yet powerful solution for managing session states, ensuring that users maintained their session across multiple requests without having to re-authenticate or reload data. This caching approach resulted in a more responsive and seamless user experience, especially during peak traffic times.

● Built and maintained RESTful API endpoints, optimizing them for better performance with techniques like pagination, rate-limiting, and response caching. To ensure that the APIs could handle large datasets efficiently, Pagination was implemented to break down results into smaller, manageable chunks, reducing response times and improving user interaction.Rate-limiting was implemented to prevent API abuse and ensure fair resource allocation, protecting the application from unexpected traffic spikes.

● Response caching was applied to frequently requested API responses, preventing repeated calls to the backend and ensuring that data was served quickly from the cache, improving the overall performance and reliability of the system.

● Participated in designing and implementing CI/CD pipelines using Jenkins, improving deployment consistency, and enabling faster updates to production environments.

● Jenkins was used to automate the entire software delivery process, from code integration to deployment. The CI pipeline automatically triggered builds and tests every time a developer pushed code changes, ensuring that code was always in a deployable state and minimizing integration issues. The CD pipeline automated the deployment process, enabling smoother and more frequent releases to production. This streamlined approach reduced human error, improved consistency, and allowed for faster delivery of features and bug fixes to end-users, enhancing the overall product quality.

● Integrated third-party authentication system OAuth2 into Java-based applications for secure user access management and simplified login processes.

● OAuth2 was used to integrate popular third-party authentication providers, like Google and Facebook, allowing users to log in seamlessly using their existing accounts. This integration not only simplified the user authentication process but also enhanced security by ensuring that sensitive user credentials were never stored in the application.

● OAuth2’s token-based approach provided a secure and scalable solution for user authentication, and its ability to support different grant types enabled flexible access management across various types of applications.

● Optimized database performance for MySQL and PostgreSQL, including query optimization and schema restructuring, ensuring quick data retrieval and reduced bottlenecks.

● Also worked on database indexing, restructuring schemas, and removing unnecessary joins, which resulted in faster data retrieval and minimized database bottlenecks. These improvements helped to maintain a smooth user experience, even during high traffic periods, by ensuring that data was accessed quickly and efficiently. Junior Java Developer
