As a Full Stack Developer, I have been involved in the end-to-end development of web and mobile applications, contributing to architecture design, feature implementation, and deployment processes. I work confidently across both front-end and back-end stacks to build scalable, performant, and secure solutions in Agile environments.

Key Contributions:

• Web Application Development: Developed dynamic web applications using ReactJS and Redux, integrating them with robust back-end services powered by Java and Spring Boot.
• Mobile Application Development: Built a cross-platform mobile app using React Native, ensuring seamless compatibility for both iOS and Android users.
• Version Control & Collaboration: Managed and collaborated on code using Git and SVN, maintaining efficient version control workflows in Agile environments.
• REST API Development: Designed and implemented REST APIs, integrating OAuth-based authentication for secure user access.
• Helm-based Deployment Architecture: Designed and implemented a reusable Helm-based architecture to standardize Kubernetes deployments, simplifying environment management and improving release reliability

Technical Expertise:

• Backend Development: Proficient in Java (8, 11, 17) and Spring Boot, with experience developing microservices-based architectures.
• Microservices: Developed Quarkus-based microservices using Java 17 and Hibernate ORM, containerized with Docker, and integrated with Microsoft Graph.
• Docker & Kubernetes: Extensive experience in containerizing applications and modules using Docker and preparing them for migration to cloud environments using Kubernetes.
• Testing & Quality Assurance: Developed and maintained automated tests using Vitest for front-end testing and Mockito for unit testing back-end services.
• Database Management: Experience working with Oracle, PostgreSQL, and MariaDB.
• Authentication & Security: Implemented authentication and authorization mechanisms using Keycloak and Microsoft Identity, ensuring secure access and integration.

Additional Skills:

• Agile Methodologies: Worked in Agile development teams, collaborating closely with cross-functional stakeholders to deliver software solutions.
• CI/CD & DevOps: Familiar with CI/CD pipelines, automating testing, and deployment using Jenkins, GitLab CI, Helm, and Kubernetes.
• Performance Optimization & Security: Focused on improving application performance, security, and scalability across the full stack.
