PROFESSIONAL EXPERIENCE

Software Engieer at Syntactech December 2023 – Present

Configured a Spring Boot project using Spring Initializr, including dependencies for Spring Web, Spring Data JPA, and MySQL.

Organized the project into a layered architecture with Controller, Service, and Repository layers to ensure modularity and separation of concerns.

Created a custom responsive web application to replace a legacy line-of-business web application using React JS.

Developed an entity model class (User.java) representing user data, annotated with @Entity to map to the MySQL database.

Implemented repository layer (UserRepository) interface extending JpaRepository to handle data access and CRUD operations on the User entity.

Developed the crucial process like Streamers and Snaps for data extraction and streaming where in used collections, multithreading I/O a great deal.

Created a service class annotated with @Service to, containing business logic for CRUD operations and handling user data.

Designed and Developed Controller Layer (UserController.java) with RESTful API endpoints using @RestController, providing routes to create, read, update, and delete users. Integrated HTTP methods (@GetMapping, @PostMapping, @DeleteMapping, etc.) to support CRUD operations.

Created and configured a MySQL instance on AWS RDS, setting up database parameters, security groups, and IAM roles to allow controlled access from the backend.

Configured application.properties with RDS endpoint, username, and password for Spring Data JPA to interact with the AWS MySQL database. Developed applications with messaging solutions including Kafka

Leveraged Spring Data JPA to simplify interaction with MySQL, with @Repository handling the data access layer.

Configured database connection in application.properties, specifying RDS instance credentials and enabling auto schema updates with spring.jpa.hibernate.ddl-auto=update.

To store the user data, I have created S3 buckets on AWS to store and serve the user information.

Developed a method in the service layer to upload user information to the S3 buckets and store the data URL information in database for easy retrieval. For easy interaction with S3 I have added AWS SDK for Java as a dependency.

Utilized the Spring Boot’s embedded server and REST APIs to build Microservices for independent services and business functions.

Contained all services using Docker and deployed in AWS with Amazon ECS and leveraged the Elastic Load Balancing. Monitored those services using CloudWatch.

Deployed the backend API to an AWS EC2 instance with an Amazon Linux 2 AMI, configuring the instance with necessary security groups and permissions.

Installed necessary dependencies on EC2, including Java and Maven, to enable runtime for the Spring Boot application. Built the Spring Boot application as a .jar file and deployed it on EC2, setting it to run in the background for continuous access.

Compiled the project into an executable .jar file and transferred it to EC2 using scp. Launched the application on EC2 using java -jar UserManagement.jar, ensuring the backend API was accessible via the EC2 public IP.

Configured Amazon CloudWatch to monitor the EC2 instance’s CPU usage, memory, and other performance metrics. Integrated logging using Spring Boot’s Logback and redirected logs to CloudWatch for easy tracking of application events and errors.

Conducted thorough testing of API endpoints using Postman to verify functionality like successful CRUD operations, image uploads, and database persistence.

Tested user information upload functionality by uploading user details to S3 and verifying URLs were correctly stored in the MySQL database. Ensured that the application could handle concurrent requests and performed basic load testing to verify performance stability.

Linked the JIRA tasks and Git branch directly to monitor the project and keep everything in sync. To keep the project automatically update the Jira issues, I have added a Git branch and Jira.

Used agile methodology in developing the application, which included iterative application development, weekly Sprints, stand up meetings and daily SCRUM meetings. Prepared the detailed documentation on project with detail and business requirements of the project.
