👋 Hi, I'm K. Thillai Nirmal
Oracle Certified Java SE 21 Developer · AWS Certified Developer - Associate
I’m a Backend Developer with strong expertise in Java, Spring Boot, and Microservices architecture, focused on building scalable, secure, and high-performance enterprise applications.
I specialize in cloud-native application development and have hands-on experience deploying production-ready systems on AWS and Microsoft Azure.
My technical stack includes Apache Kafka for event-driven systems, Redis for caching and performance optimization, MySQL for relational data management, ELK Stack for centralized logging and monitoring, Docker for containerized deployments, and Jenkins for CI/CD automation.
I also work with React for frontend integration and have a strong foundation in RESTful API design, authentication & authorization (JWT, OAuth2), and cloud deployment pipelines.
I focus on writing clean, maintainable, and efficient code, applying proven software design patterns, and delivering robust, scalable software solutions that meet enterprise standards.
