An extensive online program to build and enhance Core Java, Data Structures and Programming skills, instructor by Saurabh Gupta. I have done  MCA from Madan Mohan Malviya Engg. College, Gorakhpur (UP) and has 12 years of technical experience in Java/J2EE related frameworks and multiple domains like Telecom, Pharma, and Finance industry client experience in India and the USA.

 As you know learning in books and online tutorial is completely different than work within the organization.  Through this online training, you will learn conceptual, programming and problem-solving skills. By completing these assessment for each session you get the confidence to work individually.

I am not a full-time trainer, Currently working with an MNC in Noida and engage with projects, but I want to help students and share my experiences with others who want to get knowledge of Core JAVA and improve programming skills.

Training Timing and duration: Morning (8 to 10 AM) or Evening (9 to 11 PM)

Recommended: Students preparing for  Core-java for placement drives and employees want to change jobs.

Batch Starting Date: Starting the first batch from 15 September 2019
