Designing integrated hardware systems from architecture to deployment

I design and build electromechanical systems that combine mechanical structures, embedded electronics, and firmware into reliable working hardware.

My work focuses on system architecture, clear interface boundaries, and hardware that can be built, tested, and iterated quickly. I spend most of my time turning ideas into physical prototypes, building test platforms, and documenting the decisions that make complex systems maintainable.

30+custom PCBs designed and deployed
100+students per year on deployed hardware
2peer-reviewed robotics publications
~84%SURFER hull cost reduction

I also apply the same systems mindset through volunteer leadership in FIRST Robotics Competition, including event operations, judging, and mentoring engineering teams.

How I Build Systems

Architecture → Interfaces → Implementation → Integration → Verification → Field Learning

How I build systems diagram
  • Define system boundaries and electrical, mechanical, and software interfaces before touching implementation.
  • Prototype the risky interfaces early and test physical behavior, not assumptions.
  • Design subsystems to evolve independently.
  • Treat testing as part of design, not something done afterward.
  • Consider manufacturing and serviceability from the beginning.
  • Document decisions so systems remain maintainable years later.
  • Feed field failures back into the next revision.

Other Work

  • FIRST Robotics — Technical event operations and volunteer leadership: coordinating the large multidisciplinary organizations that deliver district robotics competitions.
  • Teaching Portfolio — College CAD instruction, laboratory development, and curriculum design for engineering education.
  • Writing & Research — Peer-reviewed publications, conference speaking, technical essays, and open-source engineering documentation.
