Work Experience
Full-stack Java Developer
Lincoln Network
- Developed non-functional HTML and CSS pages from mockups and conducted UI reviews with the UI architect and business units. Used multithreading for parallel calls within the application to improve response time.
- Created pages within the applications with front-end technologies like HTML5, CSS3 Sass, JSON, and Angular. Designed and implemented different microservices and Docker files.
- Built REST-based web services using JSON/XML messages used by the front end. Created instances in AWS and migrated data from the data center to AWS using Snowball and AWS Application Migration Service.
- Implemented all functionality using Spring Boot and Hibernate ORM. Implemented Jakarta EE components using Spring MVC, Spring IoC, Spring Transactions, and Spring Security modules.

Experience
Modernizing Financial Applications
I began by developing non-functional HTML and CSS pages from mockups, collaborating closely with the UI architect and business units for UI reviews. This improved the platform's visual appeal and functionality. I also decomposed monolithic applications into modular Spring Boot microservices, integrating them with AWS services like ECS, RDS, and ALB, significantly boosting scalability and performance.
I leveraged multithreading techniques to optimize application performance, enabling parallel processing and reducing response time. I led the migration of Java applications from IBM WebSphere to modern cloud platforms like AWS and GCP, leveraging tools such as Snowball and AWS Application Migration Service, which reduced infrastructure overhead and increased scalability. Additionally, I transformed legacy UI screens into single-page applications using Angular 8, HTML5, and CSS3.
