Product Development & Freelance Design Engineer

Ex-NASA & Tesla Product Development Engineer | Mechanical & Product Design Expert I’m an avid tinkerer, systems thinker, and product development engineer who thrives on tackling challenging problems and building authentic connections with the people I work alongside. My career has spanned from working at NASA to designing at Tesla, giving me a unique perspective on what it takes to bring products from the back-of-the-napkin concept stage all the way through to rolling off the manufacturing line. What I bring to your team: Full Product Lifecycle Expertise: I specialize in taking products end-to-end—from early concept sketches and CAD models to prototyping, testing, DFMEA analysis, validation, and production release. Hands-On Mechanical & Systems Design: Whether it’s mechanical design, reverse engineering, or complex system integration, I’m comfortable getting deep into the weeds to debug, optimize, and refine. Leadership & Strategic Vision: I thrive in leadership, design contributor, or mentor roles. I’m equally at home designing precision components as I am defining engineering roadmaps, aligning team priorities, and guiding engineering leads towards impactful goals. Multidisciplinary Strength: As a jack of all trades, my skillset bridges mechanical design, coding and controls, product research, branding strategy, and cross-functional integration to ensure your product is not only engineered to perform but also positioned to thrive in its market. Key Services: Mechanical Design & 3D CAD Modeling (SolidWorks Expert) Custom Part & Prototype Design Reverse Engineering & Redesign Design Failure Mode & Effects Analysis (DFMEA) Full Product Validation: Verification, Integration Testing, Compliance Reviews, Root Cause Analysis Product Research & Market-Informed Design Technical Drawings with GD&T Branding & Product Presentation Support My Philosophy: I believe great engineering is rooted in people, passion, and an unrelenting drive for discovery. I take pride in building exceptional cultures and products that push the boundaries of innovation – and I look forward to bringing that same energy and expertise to your next project. Let’s build something extraordinary together.
