Full-Stack Java Developer | Spring Boot Expert | Monolith & Microservi
Dhaka, Bangladesh - 4:48 pm local time
My backend stack is primarily Java and Spring Boot (with things like Spring Security, Spring Data, and Spring Cloud), but I’m also experienced with frontend frameworks like Angular and React when needed. I’ve worked with SQL and NoSQL databases, Dockerized apps, and deployed to AWS and other cloud platforms.
Whether you're starting from scratch, refactoring legacy code, or scaling an existing system, I can help you build something clean, secure, and easy to maintain.
