Baggage Sortation Message (BSM) project

An automated system that helps in efficient sorting and delivery of bags in order to reduce the wait-time of passengers

• Liaised with the client to implement an automated baggage sort system to deliver bags to respective terminals

• Involved in end-to-end data analysis and deployment of BSM thereby reducing time for baggage delivery by 70%

Reservation System Migration

Migration of System from SABRE Global Distribution System to Altea Reservation System

• Carried out the pre-production validation for International Program during schedule load- ing and coordinated with SABRE team to ensure code is dropped to test system

• Designed a UNIX based tool for PNR confirmation and achieved 85% reduction in manual efforts necessary

Projects 2017-2018

Data Analytics: Food Inspection for city of Chicago, Illinois - Python and SQL Analysis of real-time data in order to study the inspections that promote public health in areas of food safety and sanitation and prevent the occurrence of food-borne diseases

• Analyzed and manipulated correlation and dependence of each variable towards another

• Estimated the maximum likelihood of a specific Facility Type according to the level of Risk, using Bayesian approach and predicted that there would be a risk of 65% Predictive Analytics: Wine Quality Data (Red and White) - R Predictive Science methodologies to assess the quality of two different types of wine using their chemical properties

• Explored the physico-chemical properties of wine and visualized the differences between white and red wines
