Utilizing Agile and Scrum methodologies, I orchestrated efficient project timelines. Spearheaded optimization of AWS cloud infrastructure, implementing security measures for enhanced system performance.Java Development, Backend Optimization, and Web Technologies:In Java Development, I led the optimization of critical backend functionalities, leveraging Java 8 features and Java EE. Proficient in project management tools like Jira, I ensured streamlined communication. In Web Technologies, I crafted visually appealing user interfaces using HTML5, CSS3, Bootstrap, JavaScript, Angular, and TypeScript, employing Angular CLI for rapid prototyping.Database Management and Integration:For Server-side Development, I architected scalable applications with Node.js, and Express.js, and implemented Spring framework modules, including Spring Boot. Database Management involved using MySQL and PostgreSQL with Hibernate ORM and JDBC for efficient data storage.Testing and Quality Assurance:In Testing and Quality Assurance, I implemented Test-Driven Development (TDD) and Behavior-Driven Development (BDD) for robust code. Thorough performance testing was executed using Apache JMeter and LoadRunner, ensuring code quality with tools like SonarQube.CI/CD Pipelines and Configuration Management:CI/CD Pipelines and Configuration Management were integral, with seamless Jenkins, Maven, Docker, Kubernetes, OpenShift pipelines. Ansible ensured efficient configuration management. Managed version control using Git and GitHub for collaborative coding practices.Monitoring and Logging:Monitoring and Logging solutions were implemented using ELK Stack, Prometheus, and Grafana, resulting in improved system visibility and reduced mean time to detect and resolve issues.
