Kalyan P Email and Phone Number

I have extensive experience in various SDLC phases, including requirements gathering, design, development, and testing. My technical skills encompass constructing view-controller components with HTML, SCSS, AJAX, and TypeScript, and leading Java 8 to Java 11 migration projects. I have leveraged Java 8 features such as Lambda expressions and Streams, and enhanced concurrency techniques. My expertise includes developing and deploying RESTful microservices using Spring Boot, Spring MVC, and implementing dependency injection, Spring Security, and Spring Batch. I have utilized Hibernate for ORM, Spring Eureka for service discovery, and transitioned Spring Boot applications to Gradle. My front-end development experience includes jQuery, AJAX, JavaScript, CSS3, HTML5, SASS, Bootstrap, and AngularJS. I have extensive experience with Docker, Kubernetes, Jenkins for CI/CD, and deploying microservices on AWS Elastic Beanstalk. I have managed Kubernetes clusters with OpenShift, developed APIs for AWS Lambda, and utilized Selenium and Cucumber for automation testing. My agile practices include sprint planning, daily stand-ups, and retrospectives, with a focus on BDD scripts using Cucumber/Java and automation scripts for regression testing using Selenium WebDriver.

I have engineered high-performance, scalable web applications using Java 11/17, Spring Boot, and Microservices architecture. I designed and implemented RESTful APIs for efficient inter-module communication and utilized advanced Java 17 features to enhance code quality. I managed Microservices deployment and monitoring using Pivotal Cloud Foundry, migrated services from Microsoft Azure to AWS, and optimized cloud infrastructure. I upgraded legacy systems to Java 8 with Lambda expressions and Spring Boot libraries, deploying projects on AWS EC2 instances and implementing business logic for MongoDB services. My expertise includes containerization with Docker, Kubernetes management, and CI/CD pipeline establishment using Jenkins. I collaborated across teams to align technical specifications with business objectives, developed responsive front-end interfaces using HTML, JSP, CSS, Bootstrap, jQuery, and JavaScript, and secured RESTful web services with Spring Security and OAuth 2.0. I created Node.js servers for static content delivery, optimized database operations with Oracle and JDBC, maintained enterprise-level Java applications, and leveraged advanced Angular features and frameworks like Spring, Hibernate, and Apache Kafka. Additionally, I worked with React.js, implemented GraphQL APIs with Spring Boot and GraphQL Java, and ensured consistent, reliable deployments using containerization and orchestration tools throughout the full SDLC.

I led the analysis, requirement documentation, and application architecture design based on J2EE standards, extensively applying core Java concepts like collections framework, multi-threading, OOP, and exception handling. I engineered dynamic, cross-browser compatible web pages using HTML5, DHTML, CSS3, Bootstrap, and JavaScript. Using Hibernate ORM, I mapped MVC model data representations to Oracle relational database schemas and leveraged Java Collections API for enhanced security in XML, SOAP, REST, and JSON web deployments. I developed web pages with AngularJS, created Action classes and Form bean classes within the Struts framework, and implemented REST Web Services using Spring Framework features like Core, IOC, AOP, Data Access, MVC, DAO, Boot, Batch, Security, and Integration. I constructed intranet web applications using J2EE architecture, JSP for UI design, and Hibernate for database connectivity. Additionally, I implemented functional interfaces using Java 8, developed front-end, business, and persistence tiers using Struts, Spring MVC, and Hibernate frameworks, and designed database objects using PL/SQL. I created Hibernate objects for efficient data retrieval in batch and front-end processing, applied new features of Java 8's collection API, and demonstrated extensive RDBMS design and implementation across Oracle, DB2, MySQL, MS SQL, and PostgreSQL. I applied design patterns like DAO, Singleton, and MVC within the Spring framework, enhanced existing applications to meet customer requirements, worked with JSON for dynamic data display, developed persistence classes using JPA, and authored PL/SQL stored procedures, triggers, and views in Oracle. I wrote JUnit test cases for web servers, participated in Agile practices with Jira, and utilized Log4J API for logging and debugging purposes.

I have extensive experience across the entire software development lifecycle, with a strong focus on Java and web technologies. I am proficient in Agile methodologies and have worked extensively with modern frameworks and tools such as Spring, AWS, and Pivotal Cloud Foundry. My expertise spans from backend development using Java 8, Microservices, and RESTful APIs, to frontend technologies including AngularJS and responsive web design. I have implemented robust security measures, worked with containerization using Docker, and utilized various cloud platforms. My skills also encompass database management, version control, continuous integration, and testing methodologies. I have demonstrated the ability to architect, develop, deploy, and maintain complex applications, showcasing a comprehensive understanding of both traditional and cutting-edge software development practices. My experience with DevOps tools, performance optimization, and production support further underlines my well-rounded capabilities in the field of software engineering. Throughout my career, I have consistently engaged in all phases of the SDLC, from requirement analysis to testing and production support, ensuring the delivery of high-quality, efficient, and secure software solutions.
