Worked on assembling, maintaining, and enhancing our main semiconductor characterization system. Provided quality expertise from handmade components and aesthetic design to software development and signal processing. Responsible for updating in house technologies, circuit design and development, programming, prototyping, building, testing, and calibration. Collaborated with team to keep congruity across all product development.

• Developed and improved signal processing algorithms and control systems, starting with computer simulation, continuing with rapid software prototyping, and ending with embedded hardware implementation.
• Created embedded systems that replaced outsourced products resulting in savings exceeding $3,000 per semiconductor characterization system sold.
• Decreased productivity time by 500% for handmade components by creating models and 3D printing them.
• Maintain up to date manuals by keeping accurate documentation of each step-in product's design process

Maintained professional customer relationships. Translated customer ideas into custom circuit boards.. Assisted customer with circuit component selection and PCB manufacturing.

• Negotiated contracts for each project resulting in over $2,500 profit in one year.
• Communicated effectively with customers and delivered quality products resulting in several returning customers.
