Do you want to attend data science course delivered by a real time professional ?

I am an online Data Science trainer, have huge experience in Data Science, Python, R, Scala and Big Data Stack.

I have been a trainer for more than 5 years teaching various courses like Python,R, Scala, Statistics,Machine Learning,Hadoop and Apache Spark.

I have given Data Science online training for the last couple of years, trained a lot of professionals ranging from Students,Developers,Architects,Analysts and Project Leads from Companies like, GE, Genpact, Metlife-USA, HCL,Amazon,Bank of America,Microsoft,US-UK-Germany students.

I am happy to say that during all these years, all my students are 100% satisfied and working as Data Scientists without depending on others during interviews and jobs.

I don’t teach in any institutes & all my trainings are completely online !
