    Todd Blackman

    Ruby Software Engineer

    United States - Last active: 09/02/2013 - Tests: 7 - Portfolio: 1

    I have been programming for over two decades and most recently have been focusing on MySQL and Ruby development with a strong preference for Rails apps. I have extensive experience developing medium-sized to large maintainable apps using git, test-driven development, and coding toward quality so future developers can get work done fast without having to spend excessive time reverse-engineering badly written software. Other technologies I have used include REST, XML, JSON, sphinx (full-text search), elastic search, Redis, memcached, NetSuite, and mongoDB. As a web developer, it probably goes without saying that I know HTML, CSS, and Javascript (jQuery in most cases). I would be a good fit if you need complex business logic designed and modeled with less of a focus on the visual elements.

    Expert Developer specialising in iOS

    United Kingdom - Last active: 12/02/2014 - Tests: 1

    With over 25 years of experience in object oriented software design & development across a broad range of domains I have an enviable breadth and depth of skills which I’m always happy to share with the right teams. My current focus is mobile platforms and with 17 years of Objective-C experience behind me, iOS is a particular strong point; in part because it is derived from NeXTStep which I developed for long before iOS became popular. Core Data is a particular strong point and one area I see a huge amount of confusion surrounding - often resulting in bad design, poor performance and difficult to track crashes. Android is of course the other big mobile platform and with a strong history of Java based projects behind me, there is nothing to trouble me in this arena either. I’ve recently ported one of my AppStore iOS projects (“Yes Coach!”) to Android primarily because Clients do of course like to see concrete evidence of advertised skills and the App Store / Play Store both provide a great “shop front” for this. iOS is undoubtedly my primary platform but many of the underlying design paradigms, UI guidelines and general philosophy are the same of course and Android (and the associated tools) have improved so much in recent times that I find myself increasingly drawn to Android in equal measure. The beauty is that for a typical RESTful services based mobile app there is a great deal of commonality between the platforms and good design and planning can mean efficient cross platform development is an attainable goal without resorting to sub optimal cross platform solutions like Titanium for example (of which I have some experience too). Specific skills like “Java” are usually the headlines on job specifications but personally I think the most important skill is understanding the fundamentals of design and the software lifecycle. Too often I’ve seen hugely talented (and not so talented!) teams diving deep into the details of an implementation before they’ve properly addressed the requirements (implicit and explicit), the design, the testing, the tools and processes and the overall lifecycle of projects. Time spent establishing these up front is an investment that almost always pays back handsomely over the lifetime of a product / project and can reduce costs significantly. I was hugely impressed once when a Google head-hunter called me and his primary interest was in recruiting me not for any specific skill but for my general problem solving abilities coupled with my broad experience of “software” and the related eco-systems. It's a great philosophy and I concur. Anyone can say all of this of course so it is worth establishing my credentials. In the past I have held permanent roles with Microsoft Research (Search Engines, Machine Learning, Xbox Games), BT Research (Intelligent Networks) and Baxter Healthcare (Pharmaceutical). As a freelancer I have worked for many clients including GlaxoSmithKline, Microsoft and numerous "digital media agencies". I could go on, but there’s only so much you can read - so get in touch if you’ve got projects you think I can help with. I’m very flexible with respect to work with the single exception that I’m not prepared to spend my time commuting. Remote working is successful, efficient and rewarding when done correctly with the appropriate attitude, tools and mutual trust and I’m more than happy to discuss the benefits if you have concerns. Lastly, don't be put off by the headline rate, get in touch if you're interested - I'm always happy to negotiate for the right project. Thanks for taking the time to read this summary.

    I have over 10 years of experience in application development for Windows operating systems using C++ programming language. My work is mostly in, but not limited to, Exploration/Mining. I have developed some low-level code to facilitate processing of large volumes of data, including on-disk data structures design and high-throughput I/O algorithms, in-memory data layout and high-performance algorithms to make processing of large data volumes, typical for modern mining industry, a breeze. I'm also really familiar with remote debugging and crash report analysis. Have a few successful data format reverse-engineering projects.
