- As a component of Wells Fargo's digital transformation projects, I worked on creating and improving enterprise-level banking applications. Building safe, scalable, and effective microservices for customer onboarding, transaction processing, and real-time fraud detection in the financial services industry was the project's main goal.
- Actively participated in all stages of the Software Development Life Cycle (SDLC), including requirement analysis, system design, development, testing, and deployment.
- Optimized and divided massive transaction data using parallel streams and the Java 11 Streams API.
- Using Spring Boot Controllers, RESTful endpoints were implemented, and web applications were developed using Spring MVC.
- Designed microservices with Spring Boot and Spring Cloud to manage notification systems, transaction workflows, and account services.
- Using AWS Console and CloudWatch, I oversaw microservice deployments in Docker containers on AWS EC2.
- Hibernate ORM and JPA were integrated to provide secure customer and transaction data persistence.
- Using React.js, Redux, HTML5, CSS3, and JavaScript, dynamic web front-end applications were created for client portals and internal banking dashboards.
- Designed reusable React components for Single Page Applications (SPAs) and used Redux to implement state management.
- Middleware services that allow non-blocking I/O communication between client and backend services were developed using Node.JS.
- To facilitate asynchronous communication between services and enable transaction alerts and notifications, Java Message Service (JMS) was utilized.
- Created RESTful and SOAP-based services to integrate Wells Fargo's internal systems and external payment gateways.
- XML, JSON, and Amazon Kinesis were used to migrate and integrate data from legacy systems, guaranteeing real-time data flow between platforms.
- Jenkins was used to automate the CI/CD pipeline, and extensive JUnit testing, debugging, and defect resolution were carried out.
- For scalable application management, AWS technologies such as S3, Lambda, Elastic Beanstalk, SNS, SQS, and CloudWatch were utilized.
- PL/SQL functions and procedures were written and optimized to support reporting modules and backend banking operations.
- Developed MongoDB to store application logs and customer feedback in a flexible manner.
- Took an active part in Agile Scrum rituals, such as sprint planning, daily stand-ups, and retrospectives.
- Worked together on documentation, integration testing, and code reviews to guarantee audit preparedness and adherence to banking laws.
- Environment: Java 11, Spring Framework, Spring Boot, Microservices, Eclipse, JPA, Hibernate, React.JS, Redux, JavaScript, Node.JS, HTML5, CSS3, AWS (EC2, Lambda, S3, CloudWatch, SNS, SQS, Kinesis), Docker, MongoDB, SQL, JMS, XML, REST, SOAP, Jenkins, JUnit, Agile Scrum, Windows.

- Created a thorough platform for class scheduling and student enrollment for a large university client. The system facilitated real-time communication through administrative dashboards and notifications, automated course scheduling, and expedited student registration procedures. The application was created as a series of cloud-deployed, scalable microservices with mobile and web front ends that are responsive.
- Using Spring Boot and Spring MVC, we designed and implemented RESTful microservices while following the guidelines of modular architecture to ensure smooth service integration.
- Utilized Java 8 features like Optional, Lambda expressions, and Streams to improve backend performance and preserve clear, useful code.
- Using React.js, Redux, HTML5, CSS3, and Bootstrap, I created interactive and responsive front-end components that guarantee cross-browser compatibility and a consistent user experience.
- Using React Native and JSX, mobile-responsive views were created, allowing for a smooth user experience on both iOS and Android devices.
- To guarantee fast communication between the scheduling and registration services, Apache Kafka was integrated for real-time event streaming.
- Applied replica sets and sharding to increase scalability and fault tolerance; used MongoDB for adaptable NoSQL data storage.
- Using WebLogic and JMS, asynchronous messaging systems were created to enable real-time email and SMS notifications for schedule and registration status changes.
- Installed apps on AWS EC2, set up Auto Scaling Groups and ELB for high availability and performance, and configured S3 for asset storage and RDS for relational data.
- Jenkins and Maven-based automated build and deployment pipelines for continuous integration and delivery, as well as Docker-based containerized microservices.
- Using JUnit, I created thorough unit and integration tests, which helped to ensure dependable deployment pipelines and strong test coverage.
- Developed and used RESTful and SOAP APIs to connect with third-party services, such as institutional CRM systems and payment gateways.
- Developed sophisticated SQL Server functions and procedures for transactional logic, and used MongoDB to model student profiles and logs with flexible data.
- To ensure transparency and on-time feature delivery, I actively participated in Agile Scrum processes, such as sprint planning, backlog grooming, and daily stand-ups.
- Worked closely with Devops, QA engineers, and UX designers to deliver production-quality features and fix bugs quickly.
