• Designed and developed high-performance Go (Golang), Java 17 Spring Boot microservices for greenfield low-latency electronic trading platform supporting real-time transaction workflows and market data processing across multiple business teams. • Built low-latency pre-trade pricing engines and electronic trading systems for US Treasuries, Futures, and Interest Rate Swaps using Core Java JDK 17 and advanced concurrency patterns for optimal performance. • Implemented asynchronous event-driven architectures with Java concurrency utilities including ExecutorService and CompletableFuture to handle high-throughput market data streams and trade requests efficiently under heavy load conditions. • Developed scalable Spring Boot microservices exposing secure REST APIs with enterprise authentication and authorization while integrating Apache Camel v3 for routing, transformation, and enterprise services integration. • Integrated JMS messaging with ActiveMQ for reliable asynchronous communication between trading components ensuring high availability and fault tolerance in mission-critical trading systems with zero data loss. • Integrated trading platform with external market data providers such as Bloomberg/TradeWeb APIs for real-time pricing, trade execution, and market data normalization. • Collaborated with quantitative analysts to implement and enhance derivatives pricing models for interest rate swaps and fixed income instruments in real-time trading systems. • Containerized Java applications using Docker and deployed to Azure Kubernetes Service (AKS) with infrastructure provisioning automated through Terraform for scalable cloud-native trading solutions and seamless orchestration. • Built and maintained CI/CD pipelines using Azure DevOps and GitHub Actions while enforcing code quality, security scans, and gating with SonarQube for reliable production deployments and compliance.

Exposed to Agile-Scrum methodology and participated in Sprints, involving cross-functional members like architects, programmers, analysts, testers. Participated in user sessions to gather requirements and develop a web application using Agile methodology. Implemented a responsive UI that scales automatically across devices, platforms, and browsers using Angular 11, TypeScript, HTML5, CSS3, and Bootstrap. Worked on Angular 11, consuming RESTful microservices, and implemented template-driven and reactive forms for client- and server-side validations. Migrated the application from Angular 8 to Angular 11. Developed Angular components to manage view data and created Angular services for API calls using dependency injection. Extensively tested all components and services using Angular’s built-in testing framework (Karma/Jasmine). Developed components using the Spring Framework and designed interfaces to integrate them effectively. Developed dynamic Angular modules with TypeScript and NgRx for real-time Kafka-based data updates. Migrated legacy JavaScript application to TypeScript, improving maintainability and code quality. Developed REST and SOAP-based web services for data retrieval, enabling independent integration with other applications. Used Spring Framework’s Aspect-Oriented Programming (AOP) to implement cross-cutting concerns such as logging and security. Developed microservices using Spring and tested them with Spring Boot testing utilities.

• Exposed to Agile-Scrum methodology and actively participated in sprints with cross-functional teams including architects, developers, analysts, and testers. • Participated in user sessions to gather requirements and contributed to developing web applications using Agile practices. • Implemented responsive UI designs across devices and platforms using Angular 11, TypeScript, HTML5, CSS3, and Bootstrap. • Worked with Angular 11 to consume RESTful microservices and implemented both template-driven and reactive forms with client- and server-side validations. • Migrated applications from Angular 8 to Angular 11, developed components and services using dependency injection, and tested using Karma and Jasmine. • Developed components using the Spring Framework and designed interfaces for seamless integration. • Built dynamic Angular modules using TypeScript and NgRx for real-time Kafka-based data updates. • Migrated legacy JavaScript applications to TypeScript, improving maintainability and code quality. • Developed REST and SOAP-based web services for efficient data retrieval and integration with external systems. • Used Spring AOP (Aspect-Oriented Programming) to handle cross-cutting concerns such as logging and security. • Implemented logging and monitoring for Kafka using tools like Prometheus, Grafana, and ELK Stack. • Developed cloud-hosted web applications and REST APIs using Spring Boot with embedded Tomcat. • Built XML-based SOAP web services (WSDL) for handling external system integrations. • Created and managed database objects like stored procedures, triggers, views, and functions using MySQL Workbench. • Ensured seamless communication between Kafka brokers, Zookeeper, and backend services. • Used environment variables and .env files for configuration management in Docker containers. • Integrated Docker containers with CI/CD pipelines using Jenkins and GitLab CI for automated builds and deployments.

• Designed and developed enterprise applications across the full SDLC using Java/J2EE, Spring, Struts, Hibernate, and Servlets, applying core design patterns (Singleton, Factory, DAO, Session Facade, Business Delegate, Value Object) and following Agile and TDD practices. • Built and modernized web frontends using React, AngularJS, TypeScript, JavaScript, HTML5, CSS3, Bootstrap, and AJAX, creating reusable UI components and integrating them with backend RESTful services. • Developed and exposed REST and SOAP web services using Spring Framework and Java 8, leveraging Stream API, Lambda expressions, Spring AOP, Spring Batch, JMS, and Swagger for scalable, service-oriented architectures. • Implemented cloud-based and distributed solutions across AWS, Azure, Pivotal Cloud Foundry, and hybrid environments, including EC2 integration, Kafka cluster monitoring, NoSQL database design, and high-volume data processing using Spark, Hadoop, Cassandra, and Hive. • Ensured application quality, performance, and reliability through unit and BDD testing (JUnit, Cucumber, Selenium), CI/CD practices, database optimization (Oracle & NoSQL), and proactive monitoring with Prometheus and Grafana.

• Worked in an Agile/Scrum environment with two-week sprint cycles, preparing analysis documents and contributing across the full SDLC, from design and development to testing and deployment. • Developed responsive user interfaces using HTML5, CSS, JavaScript, AngularJS, JSP, Bootstrap, and SASS, and implemented backend applications using Spring MVC architecture. • Built secure and scalable backend services using Spring Framework and Spring Boot, implementing authentication and authorization with Spring Security, RESTful CRUD APIs, Spring AOP, DAO patterns, and JMS-based messaging. • Developed and tested applications using Java, Python (Flask, Django REST), Hibernate, JDBC, and Oracle databases, including PL/SQL procedures, triggers, and data access logic. • Deployed and maintained applications on AWS (EC2, S3, RDS, SQS, IAM, Route 53), implemented CI/CD pipelines using Jenkins and ANT, managed version control with Git, and performed automated testing with JUnit and Selenium WebDriver.

• Analyzed business requirements and translated them into functional and technical specifications, developing applications using Java and Mozilla XUL while aligning solutions with business objectives. • Actively involved in requirements gathering, prototyping, walkthroughs, gap analysis, and creation of Functional Requirement Specifications (FRS), ensuring clarity between business and technical teams. • Designed system architecture and application workflows, including use cases, class and sequence diagrams, data modeling (logical and physical), and user interface design. • Developed and supported applications using Java, JSP, Servlets, Spring, Hibernate, and JSF, and managed builds and deployments using ANT on Tomcat environments. • Led coordination and communication across global onshore and offshore teams, conducting code reviews, proof-of-concept development, and daily/weekly stand-ups to ensure timely and high-quality delivery.
