ABOUT ME
Core expertise in Backend Development, Data Structures, Algorithms and Distributed System Design
Core expertise in Backend Development, Data Structures, Algorithms and Distributed System Design

I can help you with the following:
-> Design/Implement large scale distributed systems and dive deep into concurrency, communication, availability, scalability, etc. Rather than just knowing Kafka, Redis and Cassandra, it's important to understand what system features you need to put these building blocks together.
-> Data structures and algorithms (Leetcode, Topcoder, etc), low level system design (object oriented programming, design patterns) and high level system design (distributed systems, etc).
-> Well structured plan and mentorship (short/long term) for interview preparation, conduct mock interviews for software engineers and senior software engineers. I have extensive experience in tech interviews, as a candidate as well as being part of panel team.
-> Mentoring for growing into senior software engineering roles.
-> Project building (end to end).
-> Pivoting from another domain/career into software engineering.
-> Other tech topics that you might be interested in (AWS, Kafka, Redis, Databases, etc).

About me:
I write software and work with distributed systems day-in and day-out. I have worked at Qualcomm in the area of smart vehicles. I have been involved with startups like Dailyhunt to build backend systems end to end; which could scale to the order of 50k+ requests a second.

Very helpful mock interview! I learned not just how to solve the problem, but also how to structure responses that are compelling and impactful

Super, super helpful! Raman really helped me build intuition about how to solve the problems. Just a few sessions in and my coding skills have already drastically improved!

I liked that Raman is calm, and we have decided how to continue. It seems to be a good start :)

We worked on breadth first search during our session. Raman explained a problem I was finding difficult clearly which aided as a building block for a harder one.
