Abhinav did an excellent job! Within four days he covered all the important concepts that are used in REAL software development. I am so thankful have him as our trainer!.
Vijay Joseph
Course - Web Development with Symfony3
I liked the trainer's communication & knowledge in Symphony 3 and associated technologies. He had taken enough effort to teach and demonstrate with some examples in the respective topics. I can say my symphony knowledge and confidence level is gone up after this training.
