Prince Raj

I am a backend-focused software developer with experience in data analytics and building production-style applications. My work combines backend engineering, data processing, and system design to build reliable and scalable systems. Previously, I worked as a Trainee Data Analytics Executive at Raghav IT Solution Service, where I worked with structured and unstructured data, performed analysis using Python, SQL, and Excel, and built Power BI dashboards to communicate insights to stakeholders. Alongside my professional experience, I actively develop backend systems and focus on learning real-world backend architecture. One of my key projects is a full-featured Expense Tracker backend application built using Java and Spring Boot. The system includes REST APIs, JWT-based authentication, PostgreSQL database integration, Redis caching, WebSocket-based real-time notifications, email reporting, PDF and CSV report generation, and Docker containerization. While building this project, I focused on implementing production-level practices such as layered architecture, global exception handling, environment-based configuration, API documentation with Swagger, database migrations using Flyway, and secure authentication mechanisms. My core technical stack includes Java, Spring Boot, SQL, PostgreSQL, Redis, Python, Power BI, Docker, and Git. I am currently focused on improving my skills in backend architecture, system design, distributed systems, and building scalable applications. I am motivated by solving complex technical problems and building systems that are reliable, maintainable, and scalable.
