Digital Design Experience
Rhino and Grasshopper

My go-to 3D design software for most projects. I am most comfortable with Rhino's command driven interface and the ability to create complex surfaces. Rhino has also been one of the primary design programs I use at Earlens. I have also worked in Grasshopper to build automations and update existing scripts.


I picked up Solidworks while taking a 3D solid modeling class at SFSU. While it has not been my primary design software, I am more than comfortable picking it back up from where I left off.


3D scan and 3D model mesh repair. Surface analyses for ProJet PM and for testing different print materials/methods at Earlens. Comparisons between 3D scan and physical object from production line.

3D Printing Experience

8+ years experience working with open-source FDM machines. Did plenty of building, repairing, and upgrading of hardware and software. Machines in use: Type A Machines Series 1, MTW Create, RostockMax V3.


3 years experience working with 3D Systems ProJet 6000 and Formlabs Form 2 3D printers at Earlens. Build setup, process monitoring, post-processing, etc.


3 years experience working with Carbon's M1 3D printer at Earlens. Build setup, post-processing, etc. Testing various resins for potential use in production. Additional experience with Asiga, Formlabs, and UNIZ printers.

Other Experience

For some mundane tasks that often resulted in human error I have been using Python to automate such tasks which in turn increases efficiency, accuracy, and even provides economic savings.

Computer hardware / software / networking

8+ years of professional experience building and repairing computer hardware systems. Software troubleshooting and repairs. Wired/wireless network setup and repairs.

Linux Server

After beginning to work with Linux on the onboard computers inside my open-source FDM 3D printers, I decided to build and configure my own personal server which is now hosting this website and other useful services.

Troubleshooting & Problem Solving

Extensive troubleshooting experience derived from years of computer repair work.

Medical Device Experience

Not only has Earlens so far given me over 5 years of experience designing their custom cutting edge hearing-aid devices, but Earlens has also exposed me to the ins-and-outs of working within a heavily regulated industry.

Tech geek and industrial designer eager to design for a better tomorrow. Quick to master new technologies and processes.
