At SportsKey, I lead the engineering team building our easy to use, cloud-based sports facility management software. We're always on the lookout for highly motivated, beyond-full-stack Ruby developers. Are you one of them? Please poke me!

Do you have an idea for a software product or service, but no idea how to get started? I help startup founders design and build web and mobile applications, from concept to launch. I offer expert advice for Discovery, Roadmapping, Technical Designs, and MVP implementation.

Travel Mobile sells SIM cards to international travellers. This is my longest running live Ruby on Rails application - it started on Rails 3.1 and Bootstrap 2 and has been kept on the latest release ever since.

Optimise is a Dublin based startup that connects shippers and carriers to take the hassle out of ordering a truck.

...and later as CTO, building out a small Dublin office and overseeing our primary team of talented software developers in the Portland office.

I rejoined LegitScript full-time, remotely from Dublin, first as a contributor....

As an independent software development consultant, I provided technical advice, system architecture and software development services to clients.

I joined LegitScript in its coffee shop days, rebuilding the initial website and database application with Ruby on Rails, starting my long love affair with that language and framework.

Unity08 was an attempt to disrupt the 2008 presidential election in the US by launching a moderate third-party candidate, chosen and supported by a grassroots, online network. I joined the team to help scale the Drupal-based platform to support tens of thousand of concurrent users. The technogy stack was PHP and MySQL on dedicated, load balanced hardware, and I had my hands in pretty much all parts of the system, including writing my first and only Facebook app.Unfortunately, the campaign itself was completely eclipsed by the Obama-Clinton primary race, and ultimately fizzled out before we could get much traction (but we did eventually get on the ballot in all 50 states!).

Hook Mobile is a provider of multimedia messaging services (or was back in 2007). I built the initial platform, a trading card system, from scratch to production launch with a campaign for CBS’ “Survivor”, on a LAMP stack.

762 Wireless provided ringtone subscription via an affiliate program. I joined as employee #1, taking over an existing PHP code base from a consultant, revamping it to modern production standards, and building up a small team.

Same gig, different role, leading a team of 5 engineers.

Mobile 365 brought text messaging to the U.S. masses. I joined IC3S, Inc, in 2001, which merged with Inphomatch, which rebranded as Mobile 365 after another merger, and was finally bought by Sybase for a neat 425 million in 2006.I set up the first text message exchange system with licensed technology, implemented core protocols and drivers specific to the US market, and over several years had a leading role in building out a platform handling millions of messages per day for all major wireless carriers in the US. Stacks were C++ and Java with an Oracle backend, SwiftMQ for messaging and an in-memory database for real-time statistics, on Windows NT, Linux and Solaris.

Netlife was a pioneer of online banking in Germany. I started as a front-end developer, cutting my teeth working on web interfaces for several banks. We used our own CGI stack written in C++. Those were the days. Later I moved towards the backend, using a mix of Python, Java, and Tcl/Tk, backed by Oracle databases. This basically started me down the road as a full-stack web developer and my life-long obsession with verbose log files.
