Precision Machining, CAD Design, Controls, Prototyping, and Engineering Problem Solving
I am a mechanical engineering student and hands-on builder with experience in CNC machining, CAD modeling, control systems, instrumentation, prototyping, and design improvement. My work includes precision machined components, experimental testing, product improvement concepts, robotics, and reverse-engineering based design projects.
Featured Work
Projects that show design, manufacturing, controls, and real-world problem solving
These are the strongest projects to feature first because they immediately show engineering depth, hands-on skill, and technical range.
PID Self-Balancing Robot
A two-wheeled robot that uses sensor feedback and PID tuning to continuously correct tilt and maintain balance.
Custom Coolant Nozzle for Mazak Integrex Tool Holders
A redesign focused on corrosion resistance, serviceability, and protecting the tool holder from damage during maintenance.
Precision Machined Parts and Inspection Work
A showcase of machining, setup, programming, and inspection work performed in a real production environment.
From concept to reality
I enjoy engineering work that moves from concept to reality — measuring, modeling, machining, assembling, testing, troubleshooting, and improving until the final system actually works.
