I have decent exposure and experience in backend application development, maintenance, and support in Python(Flask), Java and Java EE (Servlets, JSP, Spring MVC, Spring Boot, Spring Security, Hibernate, JUnit, and JPA). I also have excellent experience working on databases (Oracle, MS SQL Server, PostgreSQL, HBase and MySQL) from design to development. I have worked on a couple of applications in all stages of their development, from design to maintenance, support, and upgrade.
