I’m Andrew K. Da Costa. Born in São Paulo, Brazil, raised in Texas, and focused on turning complex mechanical problems into thoughtful, manufacturable products.
I’m good at pressure regulators. Still working on regulating how many hobbies I have.
Meet Andrew ↓I enjoy making useful things and understanding how they work. My approach combines analytical engineering, product thinking, hands-on validation, and attention to the details that make a design practical.
Outside the lab, I play tuba and enjoy music, bird watching, bird photography, cooking, camping, and country life with chickens.
New product development in pressure management, spanning product design, analysis, prototyping, testing, validation, and commercialization.
B.S. in Mechanical Engineering and M.S. candidate, with graduate work in modeling, optimization, design for manufacturing, and AI in manufacturing.
Product design and development spanning analysis, prototyping, validation, and commercialization with cross-functional engineering, operations, supply-chain, and supplier collaboration.
A Boothroyd-Dewhurst Design for Assembly study comparing direct-operated natural-gas regulators through part count, handling, insertion complexity, assembly time, and cost.
Laboratory evaluations across pressure-management product families, developing test setups and procedures, collecting performance data, and translating observations into engineering decisions.
I am a named inventor on published U.S. patent applications spanning balanced plug assemblies, adjustable boost bodies, and self-aligning or pivotable valve-disk assemblies.
