Operations research engineer with strong background and experience in developing large-scale optimization solutions using mathematical programming, constraint programming, and hybrid techniques. Solid academic and professional experiences in: 1. Mathematical modeling and analysis2. Large-scale optimization with applications in cloud resource management, transportation networks design and optimization, deposit/loan pricing, resource allocation and scheduling, military and humanitarian logistics.3. Quality-of-service provisioning, resiliency, service availability optimization in transportation networks4. Algorithm design and analysis5. Software engineering6. Research and development.Very passionate about modeling and solving large-scale combinatorial problems using decomposition methods and hybrid techniques. Some of my recently completed projects using large-scale decomposition methods: 1. A constraint programming based column generation decomposition for resource allocation in integrated systems. 2. A constraint programming based decomposition for dynamic cache distribution in Oracle Coherence3. A Column Generation based decomposition for large-scale software testing optimization4. A Cut-and-Solve method for the Virtual Network Function assignment problem5. A Column-and-cut generation for Constructing and Scheduling Multiple Forwarding Trees in Wireless Sensor Networks 6. Logic-based Benders decomposition for log analytic placement
