Product Design

We help you realize your product vision by collaborating through the design process. Using 3D CAD modeling software, we iterate on the visual and functional elements of your product idea until they work seamlessly.


Mechanical Engineering. Our experience ranges from injection molded plastic design to pneumatics and biosensors. We design your product to specified standards, no matter how simple or challenging.

Electrical Engineering. With our experience designing reliable and sophisticated circuitry, PCBs and sensors, we have successfully delivered products featuring GPS, Wi-Fi, Bluetooth, Virtual Reality (VR) and more.


We create prototypes to prove & test your product concept and help collect valuable user feedback. Our Design for Manufacturing (DFM) process ensures that all parts work and fit together off the production line. We ensure that the outsourced manufacturer we select from out network can facilitate compliance with required standards - ISO, IEC, ANSI.

Software design

Firmware Engineering. We design implement, and test embedded software to ensure that your hardware works just as it should. Our experience range control systems, biosensors, IoT, and much more.

Cloud Application Design. We architect and build applications using AWS and Azure clouds to work seamlessly with your hardware.

User eXperience (UX). We ensure your product works intuitively maximizing end user productivity.

Our Story

Drive Square was founded by Konstantin Sizov, a technology executive, in 2001 as a company that developed and sold unique patented in-vehicle driving simulators. Building Virtual Reality (VR) - based simulators required electronic, mechanical, and software components to work together.

We have worked with VR technologies since 2001 and IoT technologies since 2010, designing Bluetooth-based sensors for our driving simulators. Outsourced manufacturing has helped us scale.

During the COVID-19 pandemic, we pivoted to share our hardware and software development experience with other customers who needed help - D2 Engineering was born.

A medical device company and a biotech startup have benefited from our expertise.

“It was very important for us to develop our new generation of biosensors quickly.
D2 Engineering completed the design, prototyping and initial manufacturing run right before the harvest time.”
