Consulting Services

I have been freelancing on and off since September 2015. I offer software and hardware development services such as:

I am most comfortable working with: Python 3, C (including embedded and ISO-compliant), Javascript, and MATLAB codebases. I additionally have C++, some Rust, and some WebGL experience.

My services are tailored to individuals and companies with open source code bases who need a feature (this includes FPGA IP) or internal tool implemented. Please feel free to email me to discuss any work that you need done and rates.

Client Projects


Solvespace is an open source 3D CAD constraints solver. I implemented a THREE.js canvas for displaying models exported from the main program in any browser that supports WebGL. The canvas supports touchscreen interfaces using the extremely useful hammer.js library.

Other Projects

Outside of freelancing, I also work on open source software and hardware. I wish for electronics designs and electrical engineering knowledge to be more open and readily available to the enthused hobbyist, as it was in the past.

I have a number of long-term electronics projects. I wish to share my experience creating electronic designs with the world, regardless of their immediate utility. I contribute to making the world of electronics more open by open-sourcing my hardware and software. Through my pursuits, I also contribute to other's open source projects dedicated to keeping the world of electronics open for study at all levels of abstraction, from full system designs to individual transitors.

Many of my projects have a vintage electronics component. Projects by others that I work on are dedicated to opening parts of the electronics industry that historically have never been transparent to even dedicated hobbyists, such as FPGAs and IC fabrication.


Migen is a hardware description language (HDL) based on Python that generates Verilog.

Migen automates error-prone mistakes I make in Verilog such as finite-state-machine creation, and simulation, FPGA, and ASIC-compatible initial value instantiation. In addition to generating vendor-independent Verilog, Migen provides a unified build system to target any supported FPGA development board. Adding a custom PCB is relatively simple, being very similar to writing a user-constraints file (UCF).

Migen also provides useful clock-domain crossing and FIFO primitives as part of its standard library that I would otherwise have to import from external HDL projects.

My contributions to Migen include:


MiSoC is a system-on-a-chip (SoC) designer based on Migen. MiSoC provides a build system, a set of C and Rust libraries, and a number of Wishbone-compliant peripherals to connect to an external Verilog or VHDL CPU core (with a Wishbone wrapper). Using MiSoC, it is easy to create a microcontroller or even an embedded Linux platform on a number of FPGA development boards. A simple generic SoC is provided as an example to port to custom hardware or unsupported development boards.

Besides the SPI core refactor, my contributions to MiSoC specifically are mainly limited to Windows support. As of Decemeber 2016, I am currently using MiSoC's LatticeMico32 support to create a small SoC which interfaces with a Verilog YM2151 implementation.
