About

Software Development Engineer II at Oracle, with hands-on experience designing, developing, and deploying scalable, high-performance backend systems in fast-paced, enterprise environments. I have a strong track record of building reliable solutions that improve system efficiency, performance, and developer productivity. I specialize in Java and Spring Boot, with deep expertise in asynchronous programming, multithreading, and performance optimization. I have designed RESTful APIs with optimized database interactions, achieving up to 20% faster response times, and have effectively leveraged ThreadPoolExecutor to handle concurrent workloads at scale. I also have strong experience implementing secure authentication and authorization mechanisms, including OAuth 2.0 and JWT-based authentication. In my recent work, I built a CDC-based data synchronization system between databases and Elasticsearch, reducing redundant writes by 30% and significantly improving indexing efficiency. I have hands-on experience with distributed systems, including implementing the Saga pattern to handle distributed transactions and ensure eventual consistency across microservices. Additionally, I have worked extensively with Redis for caching, MongoDB, and event-driven architectures using webhooks and messaging systems. My expertise spans a broad range of technologies, including: Programming Languages: Java, C++, JavaScript, Dart, C#. Frameworks & Libraries: Spring Boot, JPA. Core CS Concepts: Data Structures & Algorithms, High-Level Design, Low-Level Design, Distributed Systems, Microservices. Cloud & Infrastructure: GCP, Docker, Jenkins, S3 Object Store. Databases & Messaging: MongoDB, SQL, Redis, Elasticsearch, RabbitMQ. APIs & Tooling: REST APIs, OAuth 2.0, JWT, CI/CD, Git. I am passionate about building clean, scalable architectures and delivering systems that solve real-world business problems efficiently.
