Open Source


I am the author and maintainer of libESMTP, a secure, high performance email client API included as standard in Linux distributions and in the ports section of OpenBSD and FreeBSD.


PocPlot is a simple graph plotting library for GTK+3 written as an alternative to the now unmaintained GtkExtra package.


I am a contributor to the GEGL high bit-depth General Graphics Library project used in many image processing programs including the GIMP. As well as bug-fixes, I wrote GEGL’s non-Exif file metadata subsystem.


Iarthair is a collection of open source code and tools I have written over time to ease various parts of the development process, available on GitHub.


Code contributor to open-source projects including


Senior Software Engineer

Development of GTK3+. GEGL based colour and black and white negative film scanning software simulating darkroom printing process and workflow.

This product is aimed at photography archives and museums where high throughput and conversion accuracy is important as well as the occasional user and offers a frustration-free workflow.

Oct 2018 – present Carrickfergus, Northern Ireland.

Senior Software Engineer

Use of C, Lua, XML, cryptography, database and VoIP technologies to provide secure, coordinated web and telephony services to police and local authorities.

May 2007 – July 2012

Computime Systems Ltd Leeds, England

External Consultant

I helped troubleshoot and further develop Computime’s time and attendance systems systems both in regard of electronics and firmware design. The T&A clocks were based originally on Z80 and NEC V40 chipsets were networked using RS-485 over up cable spans up to 1km cable and with a host computer using RS-232. I developed a real-time executive which implemented cooperative multitasking in C and Z80 assembler. The high level functionality was developed in C by Computime’s development team and I integrated the code into the host hardware.

As the technology in the clocks became obsolete with a consequent rise in manufacturing costs, Computime re-engaged me to develop the successor. The replacement clocks had a number of requirements over the original including the ability to communicate using TCP/IP networking and to significantly reduce manufacturing costs.

As before I developed the hardware and low-level software and Computime’s team developed application level code. The new clocks were based on Atmel’s AT91RM9200 ARM processor and ran Linux. At the time of development Linux was relatively recent on the ARM platform so I developed both utilities and Linux device drivers for the platform. I contributed patches to the then-current Linux Ethernet driver and added code to support the Ethernet PHY chips used in Computime’s design.

2003 – 2012, 1993 - 1997

Officelogic International Ltd Skipton-in-Craven, England

Senior Development Engineer

OfficeLogic Internalional Ltd developed software distributed through Internet Service Providers to simplify the process of installing and using internet software suites on Windows PC based systems. Notably OfficeLogic developed and supplied BT’s Expert Internet product.

I was responsible for the design and implementation of standards-based Internet Fax software suite including fax to email “on ramps” and “off ramps”. As part of this development process I was a participant in the IETF standards development process in the FAX and VPIM working groups both on the IETF mailing lists and attending IETF meetings.

In addition I was involved in the design and implementation of an HTTP/1.1 content filtering proxy for BT Expert Internet. This was an early implementation of detection and blocking of undesirable content as found on contemporary web sites.

1997 – 2003

Other Experience, Self-Employment

Whilst self-employed, I developed a number of small embedded devices based on Motorola 6809 and PIC microcontrollers, including beer pump dispensers, vehicle immobilisers, power amplifiers for in-car entertainment, automatic hand dryers and central heating controllers where build costs are strictly limited. I also guided clients through technical processes such as EMC testing for CE and PACT approvals.

Consultancy for ultrasonic equipment tagging and tracking for use in sensitive and hazardous environments.

Development of system to automatically monitor coin hoppers on pub games machines and reconcile reported takings communicating on-line in real time directly to companies leasing machines.

I developed higher end ARM/Linux systems for Time & Attendance systems, monitoring and verifying coin hoppers on cash based pub games machines and tyre pressure monitoring.
