About
Rogelio Castilla
Mechanical Design Specialist | Founder of Innovavision Solutions
I’m a mechanical design engineer with a proven track record in medical devices, fluid systems, and industrial hardware—combining hands-on prototyping expertise with rigorous analytical skills to deliver functional, manufacturable, and compliant designs. My work spans:
Core Design Competencies
✔ Medical Devices: Implantable bioelectronics, microfluidic systems (e.g., sweat sensors, lab-on-a-chip), and surgical tools.
✔ Fluid & Mechanical Systems: Pumps, valves, pistons, and actuators—optimized for performance, durability, and cost-efficiency.
✔ End-to-End Development: From concept to MVP, leveraging 3D printing (SLA/FDM), CFD/FEA (COMSOL), and DFM principles to slash prototyping costs by 70%+.
Why Work With Me?
✅ Industry-Blending Expertise: Unique background in biomedical + mechanical engineering—ideal for cutting-edge medical or cross-disciplinary projects.
✅ Regulatory-Savvy Designs: Intimate knowledge of FDA 21 CFR 820 & ISO 13485 ensures compliance is baked into your product from Day 1.
✅ Simulation-Driven Approach: Use of computational software such as OpenFOAM, Python, and SolidWorks Simulation to predict and resolve failures before prototyping.
✅ Startup to Enterprise Scale: Founded Innovavision Solutions to deliver agile, client-focused solutions—no bureaucratic delays.
Let’s Build Something Exceptional!
I partner with clients who value precision, innovation, and speed. Whether you’re developing a minimal viable product, refining industrial hardware, or solving complex modeling challenges—I’ll deliver designs and that work, not just CAD files.
Tools I Use Daily: SolidWorks, Autodesk (Fusion 360, Inventor), OpenFOAM, Python, SLA/FDM 3D Printing.

Houston, TX, United States
I have extensive experience in CAD design and mechanical engineering, particularly in biomedical applications. At Dr. Zhengwei Li’s B.E.S.T. Lab, I used AutoCAD to design flexible electrode geometries and photomasks, and Fusion 360 to create complex molds for cell scaffolds. I also employed SLA printing to produce high-precision, cost-effective tissue engineering scaffold molds, saving up to 50% compared to traditional bioprinting methods. In addition, I applied MATLAB and Simulink to conduct electrical and mechanical simulations for flexible biomaterials and bioelectronics, optimizing designs before prototyping. I also utilized COMSOL for CFD simulations to enhance tissue scaffold designs, ensuring optimal mechanical and biological performance.

In my work under Dr. Ran An, I utilized SolidWorks and Autodesk Inventor to design and prototype a mechanical system and protective casing for a microfluidic electrochemical sensing device for sweat analysis. I also redesigned and rapidly prototyped analog systems for syringe pumps and commercial tools to improve the device’s efficiency and significantly reduce production costs, cutting component expenses by over 50% using 3D printing and generic parts. Additionally, I optimized PDMS microfluidic chip designs to maximize gas diffusion and ensure structural integrity under mechanical stress. My engineering work directly contributed to increasing throughput in capillary microfluidic systems and enhancing device performance in the study of Sickle Cell Trait.
