Programming Languages / Data Wrangling: Python, R, Java.

Artificial Intelligence : Cortical Learning Algorithm.

Machine Learning : Random-Forests, Clustering (K-Means/Hierarchical), Regression Analysis, Text mining & Unstructured-Data Analytics, Spark MLLib.

Cloud and Big Data : Apache-Spark, Spark-Streaming, Spark-SQL, Cassandra, PySpark, Scala-Spark.

Data Visualization : Tableau, Adobe Illustrator, RAW. Data Scientist

Conceptualized and Designed a Particular Real-Life Equivalent Business Use-Case (Healthcare Data-Analytics): Based on Real-Time sensory (vitals) readings (human heart rate, activity, temperature, orientation, acceleration etc), the current physical activity of the person is predicted (Apache Spark Machine Learning Library : Spark-MLLib using algorithms Decision Tree / Random Forest Models) and the corresponding Anomalous behavior of the heart-rate is detected through the Numenta Cortical Learning Algorithm. Spark Code Development was done both in Scala and PySpark.

Major Contributor in the Design, Development and Implementation of the Backend Architecture of a Scalable Real-Time Streaming Big-Data / Analytics Platform. Data is aggregated from IoT Devices as Event Streams and Injested via the message brokers in Kafka (Data Bus Layer). The Data is then processed

(Compute Layer) where Spark Jobs (Spark-Streaming) calculates Anomaly Detection metrics and Activity Prediction Features. The results are then stored in Cassandra DB from where the services reads it (Service Layer), Jsonifies the data, directs the REST Response to a REST Endpoint from where the UI Code consumes the service. In this framework, Cluster Management is handled by Mesos and the base environment was in Python. The Entire Framework is hosted in a combination of AWS and Heroku.

Extended and incorporated open-source code from the Artificial Intelligence Framework - Numenta

( to build the Big Data Solution. Fine-Tuned and Reverse-Engineered Numenta's Hierarchical Temporal Memory based Cortical Learning Algorithm to detect Anomalies in the Data. Augmented Sequential Pattern Learning Algorithms to decipher Trends in the Data. Re-Engineered the inherent Particle Swarm Optimization Algorithm.

Product Engineering : iHealth - Connected Real-Time Streaming Data Analytics Health-Care Platform.

Data Science




Mathematically derived the functional form of a novel Geometric Brownian Motion equation that incorporates the Volatility and Drift of a Time-Series and measures Market Price Impact of Order Flow Imbalance. Made significant contribution to the body of research on Market Impact by employing our method to observe price impact that reduces error by accounting for volatility and discovered significant additional explanatory variables (price, drift of the stock etc) that quantify market impact across market states (volume, time of day, spread) thus enhancing the predictive power of the generated model over standard models. Data was extracted from the High Performance Database kdb+ and subsequent computations were performed in R. Random Forest and Stepwise Regression Algorithms were implemented for the Feature Selection.
