  Digital analytics is the prime focus area at the current role. I am majorly working on public website layout optimization, next best product offering based on collaborative filtering algorithm & model based trigger development using the customers' behavior at the different product pages of browsers. Link graph & Path analysis of web journey helps to identify the key path using relevant support and confidence.We primarily use R, Python, SAS-Eminer & SAS-VA to perform all kind of digital analytics Show less Wealth Management & Customer Analytic are the two key responsibility areas. Analysis of Income generation, behavioral pattern of different assets & liability products for different segmented customers drive towards the marketing opportunity enhancement by targeting right set of customers with the right product through a right channel.

  Senior Data Scientist

  Worked as Senior Data Scientist in Boeing R&T, Bangalore. Flight analytics on airplane health management was the prime focus for me. Analyzing various sensor data helps to identify anomaly in the system and remaining utility life of the parts. Mostly worked on acoustic sensor data (Audio) and accelerometer data (Vibration) to develop different supervised and unsupervised model such as AutoEncoder, Isolation Forest, Boosting etc. Ensemble of Particle Filtering Algorithm with Time series model on high frequency sensor data with/without trend helped business to calculate the time left for maintenance. Smart factory layout and performance improvement of air traffic management using different Computer Vision technique such as SSD, YOLO, CNN with PyTorch and Tensorflow API were other responsibility areas.
