Grizzly Peak Systems is operated by Charles Aylward and is located in Berkeley, California.

  • Product Design

    Get products to market fast with rapid prototyping for early-and-often user testing. Design (or re-design) for manufacturing to decrease bill of materials, scrap, and assembly / test costs. Design for high reliability and harsh environments.

  • Past Work

    Past work includes a broad range of systems from flight control systems for space craft and orbital launch vehicles to small low-power consumer IoT devices.

  • Turnkey Solutions

    I can provide a turnkey solution for prototypes and engineering models (we start with a blank document and you end up with a working device). I can help you with design, review, implementation, or testing for both software and hardware.

  • Analysis, Review,

    I provide the following independent review services: design verification / validation, code review, design for manufacturability, design for test.
