// Profile

Eleven years turning students into builders.

I'm a Computer Science educator skilled in teaching Fundamentals, APCSP, and APCSA soon, with deep experience in robotics, engineering, and project-based learning. I'm committed to building inclusive CS pathways that prepare students for advanced coursework, industry certifications, and technology careers — while expanding participation for girls and underserved students.

My goal is to build complete, sustainable programs rather than isolated electives: recruitment and retention, counselor collaboration, pathway sequencing, AP preparation, certifications, and student competitions — all the way to college and career readiness.

Alongside the classroom, I design and ship real software, lead robotics programs to the VEX World Championship, and create STEM content watched 800,000+ times. A diverse background — military service, finance, ministry, and software development — lets me connect computing to real-world careers.

// Robotics & Competition

From first build
to the World Championship.

I've coached and led VEX Robotics programs across every level — IQ, EXP, and V5 — taking teams to the VEX World Championship.

As a Director of Robotics, I led programs district-wide on a six-figure budget. As a coach, I've mentored students in engineering principles, programming, and teamwork — earning regional championships and World Championship qualifications, and growing one program's enrollment by 160%.

// Modern CS Instruction

Real tools.
Real workflows.

Students should graduate having used the same tools and practices as working software professionals.

My classrooms run on modern development practices — not just theory:

  • 01Python & Java programmingFrom fundamentals through AP Computer Science Principles.
  • 02Git & version controlProfessional collaborative workflows from day one.
  • 03VS Code & pro environmentsThe same editors and tooling used in industry.
  • 04Debugging & documentationSkills every employer expects, taught explicitly.
  • 05Project & portfolio buildingReal artifacts students can show colleges and employers.
