    Before the Switch#

    Omkar Gujar was already a Lead Software Engineer at Persistent Systems, a company known for demanding high technical standards from its people. He had the seniority. He had the experience. And he still chose to sit down and learn. That is the kind of mindset that separates engineers who keep growing from those who coast on their past achievements.

    He was not learning because he had to. He was learning because he understood that the gap between good and great is always filled by effort, not time.


    The Point Where Things Had to Change#

    Omkar had been a long-time viewer of Anuj Bhaiya's YouTube content and already trusted the teaching style before making any purchase. When he decided to go deep on Spring Boot, he did not look around for long. He picked up the Spring Boot 0-1 and 1-100 bundle and committed to going through it properly, all of it, from the fundamentals to the advanced concepts.

    For a senior engineer, that kind of intellectual honesty, admitting there is still more to learn and doing something about it, is rare and valuable.


    Where Coding Shuttle Came In#

    The course gave Omkar exactly what he was looking for: depth. Every concept was explained in detail with hands-on work built in throughout. It was not the kind of course where you watch videos and feel productive. It was the kind where you actually build things, make mistakes, and come out the other side with real understanding. The 0-to-100 structure meant he could move through foundational topics quickly and spend real time on the advanced material that mattered most for his goals.


    In Omkar's Own Words#

    "I was searching for detailed springboot course, luckily i was a long time youtube viewer of Anuj Bhaiya, so i got ahead with purchasing the sprintboot course 0-1 and 1-100 bundle course, pretty good deal. The course is pretty detailed and also well structured and organised, and every concept is explained in very good detail along with hands on. It covers basic concepts and goes upto very advanced concepts. All in all very good course, recommended!!"


    Where He Stands Today#

    Omkar Gujar is now an SDE-III at Entegris, stepping into a product-focused engineering role that matches the level of expertise he built. His journey from Lead Engineer at Persistent Systems to SDE-III at Entegris is a reminder that seniority is not a reason to stop learning. For Omkar, it was the reason to learn better.
