Design from various stages of concept to development for different clients from various industries.· Working to develop augmented reality (AR) device (mechanical design and optics sourcing).· Worked on multiple iterations of HMD for The Void's ( https://www.thevoid.com/ ) location based virtual reality (VR).· Optimized and sourced various lenses.· Designed and optimized multiple light guides using ray tracing software.· Worked to determine PCB layout, architecture and design for prototype wearable device.· Developed dual camera based plastic enclosure, indoor ceiling mount, and outdoor mount.· Part of development team for Motorola KRZR phone. · Modeled and rendered about 75 router bits and wood blocks in Pro/E for a catalog. Managed three people to model and render 75 more router bits and wood blocks.· Modeled master model for router and switch in Pro/Engineer using 3D industrial design IGES file as reference. Divided the master model into various pieces (top and bottom housing, etc). Created basic layout (screw locations, PCB location, etc).· Designed a planetary gear system to move a table in a circular direction.· Developed and analyzed (motion and structural) most components of miter saw arm.

Designed from concept to development, testing, and post-production troubleshooting for telematics and related products in a team environment.· Designed keypad, acoustic housing and lens for a handset from post-concept using Pro/Engineer surfacing and proceeded to release prototype tools.· Ran complete design verification testing for three products and addressed failure issues which allowed the products to pass that part of ship acceptance.· Refreshed die-cast aluminum transceiver with Pro/Engineer and released production tooling for the top and bottom housing.· Performed tolerance analysis on several key fits for a data module project.· Completed some final pre-production steps (packing and labeling spec, putting BOM into system allowing purchasing to put demand on the system for production parts).· Worked with suppliers to develop parts (prototype and production tooling) and tweak parts to pass quality testing.

Designed studies, drawings, and further support for a Micrologix PLC development project.· Designed and ordered rubber molded parts to use as a temporary measure until production parts were ready to test a three board PLC solution.· Performed FEA using Pro/Engineer-ANSYS interface and modified sheet metal part to adjust the wiping force.· Using Pro/Engineer to find interferences in the PLC assembly. Modified parts in assembly to resolve these interference issues.
