PROFESSIONAL EXPERIENCE

Confidential, Atlanta, GA

Developer

Responsibilities:

• Implemented the Multiple Vehicle Pickup and Delivery Problem with the objective of minimizing the total travel cost and the fixed vehicle cost. A branch-and-cut algorithm was implemented and formulated as a 0-1 integer-programming problem. The Pickup and Delivery Problem generally consists of a fleet of vehicles and a set of customer requests.
• Each request specifies the size of the load to be transported and the locations of two stops: pickup and delivery points.
• Furthermore, the same vehicle must visit the pickup location before the delivery location. The pickup portion of the request is considered serviced when all the units to be transported of the request are on board and the delivery portion of the request is considered serviced when all the units are landed off the same vehicle. Each vehicle has a given capacity, a start location and an end location. The objective is to minimize the total cost which may include the fixed vehicle cost and the travel cost while satisfying all customer demands.
• Enhanced existing routing and scheduling system using T-SQL/Web API written in C# which both plans out and provides instantaneous feedback on deliveries and routes.
• Created required stored procedures for implementing business logic in T-SQL as per requirements.
• Implemented another similar requirement logic in linear algebra and linear optimization using T-SQL to decide how many of products of a type fits in a box and calculate costs based on variable factors like weight of product type and whether the product needs to ship both locally and internationally. Local shipping is priced by weight and number of packages don't matter whereas the international shipping is based on weight and package size.
