Software Developer at Novidea

June 30, 2025 - July 27, 2025

As a backend-focused Software Developer at Novidea, I contributed to the full development lifecycle of web applications, primarily using the Spring Boot framework. I also collaborated across the stack, including frontend development with React and database design using PostgreSQL. My deployments were containerized and run on Raspberry Pi devices, giving me hands-on experience with Docker-based microservices in resource-constrained environments. Key responsibilities included developing RESTful and MVC-based services, building frontend components, designing and optimizing database schemas, containerizing backend services with Docker, participating in code reviews and performance tuning, and collaborating in agile development cycles.
