Experience in Full SDLC life Cycle such as Analysis, Design, Implementation, Testing, Enhancement, Production Support and Change Management of business-critical applications.
• Used Hibernate framework for back end development and Spring dependency injection for middle layer development. Database development required creation of new tables, PL/SQL stored procedures, functions, views, indexes and constraints, triggers and required SQL tuning to reduce the response time in the application.
