Java Backend Developer

I develop secure and scalable backend services for LinkPay, a US-based fintech payment platform. I build RESTful APIs using Java, Spring Boot, Kotlin, and microservices to connect merchants, customers, payment gateways, and banking systems. I also implement validation, exception handling, logging, secure authentication, payment processing, and transaction-management capabilities.

I integrate AWS S3 for secure document storage and use MySQL, Hibernate/JPA, Maven, Kafka, and Redis to deliver efficient production applications. I collaborate with Agile cross-functional teams on payment modules, code reviews, performance optimization, CI/CD deployments, and event-driven payment processing.

I also contribute to a D&B Fraud Risk Application, developing fraud detection features for device-level risk analysis and real-time assessment. My full-stack work includes Java, Spring Boot, JavaScript, Angular, JSP, Struts, HTML, CSS, and REST APIs, with deployment and production-readiness support on Red Hat Enterprise Linux.

I developed and maintained secure backend services and RESTful APIs for an enterprise insurance platform using Java, Spring Boot, Spring Security, Hibernate, and Kiro IDE. My work supported critical business workflows and focused on scalable application design, security, maintainability, and reliable integration.

I implemented authentication and authorization capabilities, including personal access token generation, API-key lifecycle management, secure access controls, and enterprise security practices. I also modernized legacy applications by migrating SOAP web services to RESTful APIs, improving interoperability, maintainability, and performance across distributed systems.

I supported deployments across Local, SIT, and UAT environments using JBoss, Git, Maven, and CI/CD pipelines. I worked with QA, DevOps, and cross-functional teams to enable stable releases, timely issue resolution, and high system availability.
