WORK EXPERIENCE

Senior Java Full Stack Developer 01/2025 – Present

3UM Denver, CO

Responsibilities:

As a Senior Java Full Stack Developer, I contributed to designing and developing scalable and high-performance web applications, implementing both front-end and back-end features that improved functionality and user engagement. I was actively involved in all stages of the software development lifecycle (SDLC), from requirement analysis and design to deployment and maintenance, ensuring clean architecture and adherence to agile principles. Leveraging Spring Boot on the backend, I built RESTful APIs that integrated seamlessly with the front-end components, optimizing data flow and reducing response latency by 25%.

On the front end, I developed dynamic and responsive user interfaces using ReactJS, TypeScript, and NextJS, implementing reusable components and optimizing rendering through efficient state management. I introduced Storybook for building and documenting UI components, which streamlined collaboration between developers and designers and accelerated development across multiple projects. My focus on UI performance and accessibility improved the overall user experience, reducing load times and ensuring cross-browser compatibility.

For the backend integration, I implemented microservices architecture using Spring Boot and Spring Data JPA, ensuring modular scalability and easy maintenance. I also integrated APIs with PostgreSQL and MongoDB databases for efficient data storage and retrieval. To enhance reliability, I applied JUnit and Mockito for unit testing, achieving strong code coverage and improving software stability across deployments. Continuous integration and delivery were achieved through Jenkins pipelines, ensuring faster feedback loops and reduced manual intervention in builds and deployments.

In the cloud environment, I worked extensively with AWS services such as EC2, S3, and Lambda for hosting, data storage, and serverless execution, ensuring high availability and cost efficiency. I containerized applications using Docker to maintain consistency across environments and collaborated with DevOps teams for deployment automation. This combination of cloud infrastructure, Java-based backend, and React-driven UI allowed me to deliver robust, maintainable, and scalable full-stack solutions aligned with business goals and technical best practices.

Senior Java Full Stack Developer 01/2024 – 12/2024

Diaconia LLC Gaithersburg, MD

Responsibilities:

Designed and developed an intelligent chat-based web application focused on real-time document query and data retrieval. I was responsible for end-to-end architecture design and implementation, integrating backend logic, APIs, and cloud infrastructure to ensure high availability and seamless scalability. Using AWS services such as Lambda, S3, and Elastic Container Registry (ECR), I deployed serverless components that enhanced performance and reduced operational overhead, resulting in a more responsive and cost-efficient application ecosystem.

I implemented backend services using Java and Spring Boot, developing RESTful APIs to manage document storage, retrieval, and data interaction layers. The APIs were optimized for secure and fast communication with the AWS infrastructure, and integrated with Python-based microservices for intelligent query handling and document parsing. This hybrid approach allowed for modular scalability and faster response times, improving overall system throughput and maintainability.

On the front-end, I developed interactive and responsive UI components using ReactJS and Streamlit, ensuring a smooth user experience across multiple platforms. The application allowed users to upload, search, and analyze documents in real-time, while maintaining secure communication with backend services. I worked extensively with Docker to containerize both frontend and backend services, streamlining deployment processes and enabling easy migration across environments.

A key achievement was the integration of LangChain and OpenAI APIs to enable prompt-engineered conversational intelligence, allowing users to receive contextually accurate responses from document data. I also configured Pinecone for efficient vector-based data storage and retrieval, which significantly optimized semantic search operations. This combination of AI-driven backend and robust full-stack design strengthened the application’s overall performance, reliability, and scalability on the cloud.

Java Full Stack Developer 05/2018 – 01/2022

IBS Software Trivandrum, INDIA

Responsibilities:

Played a key role in enhancing and modernizing enterprise-grade logistics solutions within the iCargo platform — a globally recognized product used by leading airlines and logistics providers. My primary focus was on developing and maintaining high-performance web modules using Java, Spring Framework, and Struts, ensuring scalability, maintainability, and compliance with modern design principles. I implemented multiple enhancements to improve the efficiency of cargo check-in workflows, which significantly reduced processing time and operational overhead.

On the front-end side, I led the revamp of legacy user interfaces by introducing ReactJS and Redux, transforming static web pages into dynamic, data-driven views with reusable components. This modernization effort not only improved system performance and maintainability but also elevated the user experience through faster load times and intuitive navigation. I worked closely with cross-functional teams to bridge the gap between backend services and frontend architecture, ensuring seamless integration using JSON-based RESTful APIs and robust error-handling mechanisms.

In addition to web development, I actively contributed to the iCargo Android application by integrating new features and fixing existing defects using React Native. This cross-platform implementation optimized code reuse and improved delivery cycles. My enhancements to the mobile platform increased overall application stability and performance, resulting in a smoother end-user experience for airline staff managing real-time cargo operations.

A major highlight of my tenure was improving code quality and test coverage across multiple modules. By introducing JUnit-based automated testing, I raised test coverage from 20% to 95%, significantly reducing production issues and ensuring system reliability. I also collaborated with QA and DevOps teams for continuous integration, code reviews, and release readiness. My contributions directly strengthened system performance, enhanced maintainability, and aligned development practices with enterprise-level quality standards.
