Wossname Industries

Ruby on Rails, iOS, and DevOps meets design, development, and teaching.

Wossname Industries is Graeme Mathieson's software consultancy. I build Ruby on Rails web apps. I build iOS apps (for the iPhone, iPad and Apple Watch). I make the web apps talk to the iOS apps. And I can build the entire hosting infrastructure that allows you to deploy & scale your product. In short, I can do it all!

I'm one of those types of folks who can turn their hand to a bit of everything. I do web app development, using the Ruby on Rails framework. I do iOS development – apps for the iPhone, iPad, and Apple Watch – with Swift. I cover the full gamut of services that come under the DevOps banner. And I'll even project manage myself into the bargain. If you're looking for a good all-rounder who can be your entire development team then, as Leonard Cohen sang: I'm your man!

More on services On to projects


I've always got a few side projects on the go. It's a great way to learn about new technologies, or to brush up on a particular skill. Right now, I'm making sure I'm up to speed with the upcoming release of Ruby on Rails 5. I'm also playing around with iOS 10 and Swift 3.0 – in particular, I'm exploring what CareKit and ResearchKit can offer for building apps to help manage your mental wellbeing.

I only just discovered Domain-based Message Authentication, Reporting & Conformance (DMARC) today, as I was writing up some notes for an article on setting up email for a new domain. While I was writing the section on DKIM, I got to thinking, That's all well and good, but how do I advertise the fact that all my email sources are DKIM-signing messages, and that anything which isn't signed is probably spam? It turns out that DMARC is the answer to that question — and more — and it's widely deployed. In addition to allowing you to state that you sign everything, you can also opt in to getting reports from mail service providers with details on what email is getting dropped. Read more…

On to testimonials


Some of the people I've worked with in the past have said really nice things about me. I thought I'd share a few of them with you, mostly because it makes me feel good about myself!

Graeme acted as a technical consultant to Sourcerail, providing me with essential guidance and backup. The breadth and depth of his technical and commercial experience allowed him to guide us to the correct technical and business solutions to the challenges we faced while developing the application.

Working with Graeme was an absolute pleasure.

I did some Ruby on Rails development work for Graeme recently, which was both a pleasure and an education. Graeme is one of those rare guys that is as comfortable talking to clients and interpreting their needs as he is coding the solutions to meet those needs. He knows Rails inside out but, more importantly, he also knows how best to use it to deliver great results for his clients. I learned a great deal from him during the project.

Highly recommended. I really enjoy working with Graeme. He is extremely good at what he does. He is very trustworthy, his code is of impeccable quality, and, for most programming tasks, he is fast - very fast. He probably thinks and types twice as fast as me! If these are qualities that you are looking for, especially trust and quality, then he is very good value for money.

Graeme is one of the most patient, meticulous, laid back and approachable people I've ever had the pleasure to work with. His Engineering skills are at a level I aspire to, and he's been a constant source of inspiration for the time we were working together. Any team is strengthened by having Graeme on it.

It was great working with Graeme. If you go to him with anything, he'll always have some valuable insight. He is extremely helpful and does everything to a high standard. I can't recommend him highly enough.

Graeme is a top-notch engineer who possesses vast and detailed knowledge about the technical inner workings of FreeAgent. He also takes on big technical challenges and sees them through. I have learned a lot from him!

It's rare enough to find someone that's good at one role, but Graeme somehow manages to be both an awesome technical lead and a great project manager. He has a wealth of experience and an ability to communicate both at a high level -- which makes it easy for non-technical people to understand -- and with the attention to detail that geeks crave. Any project that involves Graeme is going to be a massive success and a lot of fun.

His rich knowledge of Ruby on Rails, systems architecture and the Internet in general, combined with his practical and pragmatic approach, kept the delivery team relaxed and productive. This enabled us to successfully deliver a large system from a hugely complex set of constantly evolving requirements.

Azalea Innovations has used Graeme on a number of occassions, most usually to fix mission critical issues that we simply cannot handle in-house. Each and every time we are impressed with how he just gets on with it, makes things work and calms everyone down in the process.

Graeme is clearly one of those people who just understands what needs to be done. Working with incomplete, inconsistent, and often incoherent briefs, Graeme keeps his cool and works his magic.

We simply cannot recommend him highly enough.

The Behind the Medical Headlines site was a fairly successful pilot which we were very keen to develop further, but the site design was becoming dated, was not very user-friendly and was manually intensive in terms of staff support. As such, its ongoing development was not sustainable in its previous form.

As a result of engaging [Graeme], we now have a considerably more attractive site which is not only more user-friendly and includes a range of new features which could not have been supported under the former design, but is also considerably easier to update.

The work undertaken by [Graeme] has enabled us to reduce staff time required to support the site by approximately 300% and has increased options for staff support and cover through its easy-to-use interface. This has, importantly, provided a considerably more sustainable platform from which we can develop and support the site further.

In closing, I would add that once briefed, [Graeme] provided an excellent tailor-made service and I would strongly recommend [Graeme] to others similarly wishing to redevelop and redefine their online presence.

Aren't they kind? :-)

Wossname Industries is based in Devon, in the South West of England. It's a beautiful part of the world! I've got beaches, and cliffs, and moors, and the city of Exeter, all within easy reach of home. The weather's not too bad, either.
