I build projects at the intersection of biomedical engineering, computer vision, medical technology, and 3D design. This portfolio is a running collection of engineering projects, research, and things I'm building to explore how technology can improve healthcare.

Computer Vision / Biomedical Technology

Gesture Controlled 3D Anatomical Visualizer V1.0

Description: Developing a computer vision interface that uses a standard laptop camera to track hand and fingertip movements and translate them into real time manipulation of 3D anatomical models. The system is designed to explore a contactless approach to interacting with anatomical visualizations, with potential applications in surgical environments where minimizing physical interaction with computers could be beneficial.

The current prototype uses hand landmark detection to control 3D model rotation through fingertip movement and zoom through a pinch gesture. The application supports OBJ models, with additional support for STL and PLY formats. Future versions will explore integration with full scale MRI and CT brain scans, higher performance rendering, and more advanced interaction with high resolution anatomical data.

Medical Devices / SolidWorks

Intramuscular Autoinjector

Description: Designed and modeled an intramuscular autoinjector in SolidWorks, developing a detailed 9 part mechanical assembly based on the architecture of an existing autoinjector. The project explores the mechanical design of automated drug delivery systems, including needle protection, syringe stabilization, spring driven actuation, and trigger mechanisms.

The assembly was developed as 9 individual components: needle safeguard, needle stabilizer, needle, prefilled syringe, plunger, compression spring, spring housing and trigger assembly, end cap, and outer housing. Each component was modeled independently and assembled in SolidWorks to evaluate component fit, alignment, and mechanical interaction within the complete device.
