Sumit’s Resume
I can help you either set up a data culture from scratch or grow it exponentially from the current state. I have worked on the scale of millions in the first organisation and billions in the second one, hoping to scale myself and the systems to handle trillions of data points.
What makes me qualified:
- Helped build a team of upto 10 distributed data engineers from non existent team of 2 engineers in a span of 3 years along with fulfilling the analytics requirement of organisation and ever growing data
- Built “Data transformation platform” from scratch and led a team to build “Data integration platform” in the current organisation with the aim of data democratisation. These platforms handled most of the use-cases present with data and pushed the company to be more data centric.
- Built distributed, resilient and scalable the systems to handle millions of data points in first organisation and then upto 10s billions of data points per month in the current one.
