About

-

Engineering is where ideas meet wiring, tolerances, and inconvenient reality.

+

Embedded control, pneumatic actuation, and mechanical design.

-

My work sits at the intersection of mechanical design, embedded firmware, controls, and pneumatic actuation. I enjoy building systems that move, sense, respond, and provide measurable feedback rather than remaining as clean diagrams on paper.

-

I value clear documentation, practical testing, and honest limitations. A design that works only in a slide deck is decoration; a design that survives troubleshooting earns respect.

+

I develop controller firmware, sensor interfaces, pneumatic actuation systems, and mechanical designs. My projects include physical prototypes, simulations, and measurement-based testing.

+

I document system architectures, test setups, measurements, and limitations alongside the designs.
