Suraj Shelke

Bsc Computer Science | Certified Cassandra Trainer

11 Years of Experience

I have now worked in IT for over 10+ years with more than 5 years into Cassandra database activities, a thought that fills me with a combination of both pride and growing honor.
I obtained Bachelor's Computer Science in 2009, from S.K.Somaiya College, Mumbai University, and pursuing an MBA from D.Y.Patil University plus a Certified Cassandra expert, After completion of my graduation in Computer Science, I was employed in my first IT position as a Consultant with Nelito(On contract) for the client Bank of Baroda with India’s well known Bank. In such a big Bank I got the opportunity to work on the RRB migration project from Bibas to Finnacle. Meantime completed my Oracle 9i/10g OCP. In 2011 I joined Electracard services (ECS) an opus company that is now acquired by MasterCard which is a big giant in the payment domain industry. In ECS I got the opportunity to handle the queries of SBI and its associate banks. So, I got good exposure to Banking Domain (including debit card, credit card, ATM, etc.). In ECS I worked in various roles, including Database Administration, Database Design, and other Database Activities. The maximum of my career was with Digite Infotech a Product Company as lead database and with Wipro as a Senior Cassandra admin. Currently as Nosql Database Manager at Reliance Jio.
I consider myself a learner and always thirsty to know more. Knowledge is one thing that excites me, and I feel that it increases by sharing. Worked on multilingual database relations as well as NoSql such as Oracle, MS Sqlserver, MYSQL, Cassandra, MongoDB, HBase, Hadoop & its components other than this In-Memory DB OLTP.
Designed and implemented logical and physical database models. I have a solid techno-commercial background that allows me to make better decisions for my employer/clients based on the cost-effectiveness of different solutions.
I can be contacted at suraj1287@gmail.com for any inquiries or any corporate or personal training in NoSQL (Cassandra).

First of all a big thanks to Mr. Suraj who is our tutor for the "Online Cassandra ready course" It has been a really great experience! Normally when we join any course it's a bit cautious for everyone whether I will be able to cope up with the speed or knowledge but interestingly our tutor made sure everyone feels comfortable in terms of knowledge and speed at which course is progressing. The course started with a very basic lecture so even one who doesn't have any knowledge of Cassandra will be able to pick up, in my case I have experience in Cassandra but it was a good brush-up to move forward. Apart from the theory part, the one thing which is most useful is practical and this course provides hands-on with your own systems & error resolution you have & keeps everyone at the same level. After every practice session, one day time is provided to practice yourself and come back the next day to resolve your issues if you have any. All the topics which are taken for practical purpose are actually used for Cassandra Administrator in real work.so you will gain confidence whether you are currently working on Cassandra or you are planning to move on the same. We got material with steps provided in it and not to forget interview questions which are really helpful if you are planning to switch your job. Cassandra doesn't have much content on the online platform but the tutor himself has vast experience on Cassandra, so we were relatively much close to actual office work.

Overall best guide and coach for the Cassandra DBA course. I can suggest everyone to join the class with Suraj who is looking for a career in Cassandra.

The best guide for people who are looking for the transition from SQL to NoSQL word. He is having vast experience in managing the Cassandra database from capacity planning to production-ready deployment and monitoring to performance tunning. Highly suggested for those who want to dive into the NoSQL by gaining not only theoretical but also practical knowledge from one of the best in the industry.
