Matthew Roy, one of the founding engineers of Sandbox, is a Mechanical Engineer from Richmond, Virginia. For Sandbox Engineer and Design's clients Matthew provides detailed manufacturing and mechanical design expertise. Whether the product quantity is two or two million, he has the skills and experience to optimize the design for the lowest cost while maintaining considerations for other design factors. When detailed quantitative analysis is necessary, Matthew uses extensive experience with quantitative modeling to evaluate designs and provide the Sandbox team with hard numbers upon which to make trade studies. Able to work closely with other engineering disciplines, Matthew integrates designs to produce cohesive products that tightly integrate computing, sensing, and actuation.

Matthew has collaborated on small projects and led large projects, including DoD projects valued at over $230 million. Matthew graduated from Franklin W. Olin College of Engineering with a Bachelor of Science degree in Mechanical Engineering, Matthew has extensive project experience. He has worked with low volume machine shops and produced parts with high volume processes. Projects of note include development of gyrostabilized prototype vehicles, plant waste heat recovery and monetization for DRS Technologies, system design for energy efficiency for DRS Technologies, LED light manufacturing design, cup holder usability redesign, and surgical simulation design.

Matthew has manufactured prototypes and revised designs to support improved manufacturability in production. Developed designs for short run processes including FDM, WaterJet, Laser Cutters, 2-, 3-, and 4-axis CNC mills and lathes. Designed and optimized parts for long-run manufacturing including injection molding, vacuum forming, manual welding, robotic welding, and casting.

Other notable prototypes developed and manufactured include: Built prototype parts for reduced-weight passenger seats for Boeing, wireless pressure taps and test instrumentation for Pratt & Whitney, vehicle components for SAE Baja, vibration monitoring and test equipment, and bio-materials testing equipment.

Matthew has extensive experience with projects for the Defense Logistics Agency and the Department of Defense, including performing acquisition analysis. Performed quantitative analysis of new systems for feasibility to support DLA Information Technology objectives. Performed quantitative and qualitative analysis of alternative courses of action including: technical risk analysis, technical feasibility assessment, cost estimation using activity based costing, risk assessment, sensitivity analysis, operational benefits assessment, variable costs analysis, total ownership cost estimation, and return-on-investment calculations. Matthew's analysis evaluated viable alternatives for cost and benefits to DLA. Benchmarked existing commercial systems and government information technology systems for DLA. Analysis of software packages for electronic ordering by DOD & Civilian agencies. Performed modeling of transaction and user growth from development actions based on industry best practices and case studies. Estimated costs and savings from changes in capital development and operational practices.

Implemented information engineering projects to develop requirements, design systems, and lead the implementation to support engineering objectives. Integrated data from various sources to create a comprehensive analysis, including active data migration from Sybase, PostgresQL, legacy database systems and .NET connectors into MySQL.

For entertainment, Matthew runs several linux servers (Ubuntu server distro), and meddles in photography. He also maintains a Volvo 940 Turbo sedan and a Volvo 940 wagon, with stock engines and a not-quite-stock computer systems.
