Some of the projects that I have worked on are,1) Designed and Implemented a machine learning system that predicted the most probable questions which the seller can ask. This helped us reduce the contacts significantly. It was implemented as a REST service. This service had high throughput and low latency requirements.

2) Designed and Implemented a map-reduce based feature selection system which worked on terabyte scale of data. Also exposed this system as a service. This is used extensively by internal teams.

3) Designed and Implemented a scalable, distributed and fault tolerant model building pipeline using AWS SWF (Simple workflow service) and AWS EMR (Hadoop in AWS Cloud). Also exposed this system as a service. This is extensively used by internal team to develop models.
