I found Shrikanth's mentorship program to be highly effective and beneficial.
Shrikanth's mentorship program was incredibly structured and effective. He clearly outlined the process, providing me with specific topics and resources to study. Once I was prepared, he conducted thorough mock interviews, offering valuable feedback that helped me identify and address my weaknesses. This step-by-step approach ensured I was well-prepared for every stage of the senior front-end developer role.

Overall Experience was good and now I know a lot especially in JS, CSS, HTML than I used to know earlier.
I got to learn a lot of things especially in the JS which I did not earlier. Also I got to learn how things work internally and how we should prepare the parts which gets missed by only watching tutorials. In depth discussion on these things were very helpful.

Found an amazing mentor and a friend in him.
He came up with a very clear path to how I can achieve my goal. The primary focus was on strengthening my basics. By basics, I mean the depth required to understand a topic inside out. Getting mentorship from Shrikanth has been a great experience.

The experience learning from Shrikanth has been very engaging.
Shrikanth has been very straightforward in giving critical reviews that has improved my learning a lot. His way of teaching is very crisp and explains the hardest of the concepts in the most easy way. In addition to that, his methodology of citing real life examples makes understanding the topics even more convenient.

Transformative DSA course, brought clarity to complex concepts.
FRAZ's DSA course provided a transformative learning, loved the way of teaching concepts. The well-structured, stepwise content with practice problems and engaging teaching style brought clarity to complex DSA concepts. Live-classes vibes are top-notch! Offered a thorough understanding of each topic. Totally worth my time and money.

Amazing teaching skills. Fraz makes even the most difficult topic easy to understand
As I was not from an IT background, I was always scared of coding. But the way Fraz taught, he made it very easy to understand. He made me solve a lot of problems on each topic with a step-by-step approach. I was able to crack Uber, Amazon, and Microsoft, and the best part is that I didn't pay Fraz, as he is my brother
