// Who I Am

About Me

I'm William Roche, an Electrical Engineering student at Florida Polytechnic University graduating in May 2027, with hands-on experience designing and building real hardware from the ground up.

My work spans custom PCB design, embedded systems, power electronics, and autonomous robotics. I've built flight controllers, power distribution boards, and collaborated on research-adjacent hardware projects — all while serving as a Teaching Assistant in the EE department. I care about getting the details right: clean schematics, solid layouts, and boards that actually work when they come back from fab.

I offer freelance PCB design and consultation services to startups, researchers, and hardware teams who need reliable, well-documented designs delivered efficiently.

// How It Works

The Design Process

A structured workflow that keeps your project on track from first contact to final Gerbers.

01
Discovery

Share your specs, constraints, and goals. Free 30-minute scoping call to align on requirements.

02
Proposal

Receive a detailed scope, timeline, and fixed-price quote within 24 hours.

03
Design

Schematic first, then layout with milestone check-ins for your feedback.

04
Review

Design rule checks, signal integrity review, and DFM validation before handoff.

05
Delivery

Gerber files, BOM, pick & place files, and all native source files. Fab support included.

Project Portfolio

Real hardware built from scratch — schematics, layouts, and test results across power, control, and embedded domains.

Atlas Flight Controller v0.6 3D render
Flight Control 4-Layer RP2350A In Development

Atlas Flight Controller — Quadcopter

Custom 4-layer flight controller PCB built for a GPS-denied autonomous quadcopter that uses computer vision for flight with radio-transmission override. Designed around the RP2350A microcontroller from Raspberry Pi, featuring a 9-axis ICM-20948 IMU, BMP384 barometer, 16MB flash (W25Q128JVS), and an automatic power-switching circuit supporting both micro-USB and external 5V input from a PDB. Layer stack-up uses top/bottom for routing, second layer as GND pour, and third layer as 3.3V pour. PID-based motor control firmware runs on-board.

Dual Channel Power Supply PCB
Power Electronics Manufactured & Tested KiCad

Dual Channel Power Supply PCB

Dual-output regulated power supply designed to power sensors and a radio receiver on a custom autonomous drone. Takes 12V input from a PDB and provides independently switchable 5V and 3.3V output channels via onboard blue toggle switches. Both outputs tested as accurate and stable with minimal heat under load. Gerber, BOM, and pick-and-place files included for direct ordering. KiCad source files are open access.
