CAREER SUMMARY

Got over 11+ years of experience as a Java Full Stack Developer, where I've worked on building enterprise applications in sectors like finance, healthcare, HR/payroll, and aviation.

Well-versed in Java versions 8 to 17, plus Spring Boot, Spring MVC, Spring Security, and Spring Cloud for backend development.

Experienced in designing and building cloud-native billing systems and transaction processing solutions with real-time workflows targeted at financial institutions.

My experience includes creating secure RESTful APIs and SOAP web services, implementing OAuth2, JWT, and LDAP authentication, all while ensuring compliance and data protection.

On the front end, I’ve developed Single Page Applications (SPAs) using Angular (2 to 13), along with TypeScript, HTML5, CSS3, Bootstrap, and React 18 to create responsive user interfaces.

Applied Spring’s Dependency Injection, Annotations, and AOP to break down business logic and handle cross-cutting concerns.

Maintained and modernized legacy JSP based modules, refactoring them into Spring Boot microservices and Angular components.

When it comes to improving user experience, I have worked with Angular Reactive Forms for form validation and added Bootstrap alerts and reusable components.

Designed scalable microservices architectures leveraging Spring Boot, Docker, and Kubernetes, deployed across AWS, Azure, and GCP.

In cloud deployment, automated infrastructure provisioning using Terraform and AWS CloudFormation.

Brought Generative AI (Gen AI) and LLM APIs into enterprise billing workflows for tasks like anomaly detection and conversational support.

Hands-on experience in integrating Kafka, RabbitMQ, and ActiveMQ to support event-driven communication and real-time data streaming.

On the database side, I’ve configured MongoDB clusters, handled JavaScript DML operations, and managed Cassandra clusters, focusing on replication strategies.

I’ve designed normalized schemas in PostgreSQL, optimized queries, and used Hibernate/JPA ORM for effective data persistence.

Moreover, I've developed Spark transformations and MapReduce jobs, integrating Hive queries through SparkSQL for big data processing tasks.

For monitoring, I’ve leveraged tools like AWS CloudWatch, ELK Stack (Elasticsearch, Logstash, Kibana), Splunk, Grafana, and Prometheus.

Experience in setting up batch processing jobs with Spring Batch, incorporating retry and skip logic for claims reconciliation and reporting.

My design approach includes utilizing patterns like Session Facade, Factory, and Singleton to enhance service orchestration and maintainability.

Conducted unit testing with JUnit, Mockito, and Groovy, and validated APIs using Postman and SoapUI.

Experience supporting financial institutions and capital markets workflows, including real time transaction processing, billing systems, and compliance driven API development.

Also, I’ve practiced Test-Driven Development (TDD) and Behavior-Driven Development (BDD) to ensure my code is both robust and maintainable.

I've integrated Groovy scripts into CI/CD pipelines with Jenkins, which has enabled automated testing and deployments.

Experience in setting up automated builds and regression testing using GitHub Actions and Azure DevOps pipelines.

On the containerization front, I've used Docker Compose to manage multi-container applications and deployed services on Kubernetes clusters.

To optimize API response times and boost system performance, I’ve implemented Redis caching strategies.

Working in Agile Scrum teams has been a big part of my experience too; I've participated in sprint planning, daily stand-ups, retrospectives, and backlog grooming.

Conducted code reviews, mentored junior developers, documented technical specifications, and made sure we delivered high-quality software.
