    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.

    So, you have a problem, which you believe should be solved with some software system. If you DO HAVE a solution to your problem (or at least an understanding) and need an implementer – most likely, I am not the one you need (though there is always some place for exceptions!) But if (check one or more): 1. You DON’T HAVE even an idea what to do with your problem 2. Your problem requires a COMPLEX approach 3. Your problem has TOO MANY points of solving at once. then I am the right person to ask for help! Because that is what I am seeking here: problems that need unique approach. I am seeking people who need a uniquely complex service: some blend of consulting, analytics, planning, research, solution design, coordination, development, and support. Well, this is not a marketing trick! I really can deliver this kind of service. For many years, from my early days at the university I’ve been carefully collecting knowledge, building a holistic vision of the industry. I’ve been developing universal skills and training my mind. And then I empowered all that with a diverse experience! I have also built a really great network of professional connections. So I can always find a great implementer for your solution (in case I cannot implement something myself). And I can always assure the best imaginable control over that implementation! Curious analytical mindset and moderate perfectionism are the core of my approach to problem solving. My background in general: I am a Ukrainian computer science and information technology professional with over 6 years of intensive commercial and academic experience. My primary expertise covers enterprise software platforms and software engineering. My research interests cover component-based software engineering, information retrieval, and multi-agent systems. I am accustomed well to working both in large distributed organizations within multicultural environments and small autonomous teams. For several years I am successfully combining engineering, communicative, research, and teaching activities. Broad experience gained during these years enables me for both general IT advisory as well as ad-hoc R&D challenges. All my experience was tightly accompanied by intensive communications with partners and customers all over the world, including Fortune 500 enterprises. I have been dealing with problems at industry giants, supporting high-load business environments.
