• Created a service discovery mechanism using Eureka and implemented circuit breakers with Resilience4j, reducing system downtime by 80% and ensuring graceful degradation during partial outages.

• Architected a hybrid database solution utilizing Oracle for transactional data and MongoDB for real-time market data, optimizing query performance by implementing database sharding and indexing strategies.

• Developed efficient data access layers using Spring Data JPA and MongoDB repositories, reducing average query response times from 500ms to 120ms for complex financial data retrieval.

• Designed and developed RESTful APIs using Spring WebFlux and reactive programming, capable of handling 3000+ concurrent user requests for real-time market data access.

• Implemented comprehensive API security using OAuth 2.0 and JWT tokens, ensuring compliance with financial industry standards and successfully passing external security audits.

• Created detailed API documentation using Swagger/OpenAPI, reducing integration time for client teams by 60% and decreasing support tickets by 40%.

• Utilized JMeter for load testing and YourKit Java Profiler for performance analysis, identifying and resolving bottlenecks that improved overall system performance by 45%.

• Implemented comprehensive monitoring using Prometheus and Grafana, creating custom dashboards for real-time visibility into system performance and business metrics.

• Developed automated alerting mechanisms that reduced mean time to detect (MTTD) issues from 30 minutes to 5 minutes, improving system reliability and maintenance response times. Java Developer Capgemini, India Sept 2020 – Dec 2022

• Focused on enhancing the performance of a global e-commerce platform by improving response times, reducing latency, and increasing scalability.

• Adopted a microservices architecture using Java Spring Boot, enabling rapid development of independent microservices, and reducing response times through decoupling application components.

• Created data models and implemented database interactions utilizing Hibernate and Java Persistence API (JPA) for effective data persistence.

• Designed RESTful APIs to facilitate efficient data flow and communication among various system modules, ensuring real-time information exchange.

• Implemented caching mechanisms, specifically Redis, to alleviate database load, which significantly decreased the number of database queries and improved page loading times.

• Embraced Agile methodologies to iteratively develop and deliver features, resulting in higher project velocity, enhanced collaboration, and adaptability to evolving requirements.

• Utilized Docker for deploying microservices and application components, ensuring consistent environments and achieving a 40% reduction in deployment time.

• Integrated Jenkins into the development pipeline to achieve Continuous Integration (CI) and Continuous Deployment

(CD), automating build, testing, and deployment processes to significantly minimize deployment errors.

• Developed a data storage engine using MongoDB to manage product data and implemented recommendation algorithms to suggest products based on user behavior and preferences.

• Enhanced API documentation with Swagger OpenAPI, resulting in a decrease in support requests related to API functionality.

Java Developer SoftAge Information Technology, India Jan 2019 – Aug 2020

• Developed a server-side application utilizing the Java programming language and Spring Boot framework, creating RESTful APIs to manage CRUD operations for supply chain data.

• Utilized relational database management systems such as PostgreSQL or MySQL to design and implement tables for key entities, including products, inventory, orders, suppliers, and customers. Executed indexing and normalization strategies to optimize data storage and retrieval efficiency.

• Adapted RESTful APIs with Spring Boot to facilitate effective communication between application components, enabling seamless integration across the system.
