    My website is available at http://www.rehanjaffer.com/ for some idea of what I do in my spare time, programming-wise. As a child I aspired to be an inventor. Lego blocks, circuits, anything I could get my hands on, I'd experiment with and learn what I could do with it. I dreamed of a day when I would be able to build a robot myself. Programming was been the first practical realisation of that aspiration, as it allowed innovation and creation, the ability to dream or envision a website or application and turn it into reality. With the right set of tools, an idea can be brought to life. As a result of what some might call 'obsessive traits' my knowledge is quite diverse and in many cases the interests merge. My own deeper studying of psychology aids in eCommerce development and design by understanding the need, where possible, for empirical testing, along with being able to apply standard human behaviour (i.e less clicks to purchase leading to a greater chance of buying). It has also lead me to understand my own blind-spots and where to compensate for them in programming. An example of this would be the confirmation bias experiment where participants were asked to identify the next number in a sequence and work out the rule. The sequence they were given was 2, 4, 6. Most correctly guessed the next number would be 8, but incorrectly guessed that the rule was "adding 2 to each new number", when in fact it was simply "any set of ascending numbers". The failure to test alternative hypotheses was confirmed in other similar experiments, and there are practical applications of this in unit testing. A simple example being testing the cases that should work, and not testing cases that shouldn't, something far too common. In development, this has resulted in me specialising in a few key areas (specifically Rails and Ruby) while also understanding the full stack from servers down to interpreter internals. I'm able to write code in most major languages, but to truly know a language requires learning the idioms, experiences with common issues and bottlenecks, and knowing the best practices.  less

    Hi, I'm Ruby on Rails developer with huge bag of knowledges. First of all I wanna talk about programming experience. My first professional experience starts with Ruby but before it I learn a lot of C/C++ in Tver State University. So I have all basic skills which university give to his students: algorithms, math, machine learning, web development, database architecture, mobile development, mathematical modeling, working with signals, computer graphic, security and encryption, etc. Also in university I have build an Android application for streaming audio-data between several devices via bluetooth. But my best side in programming skills is Ruby on Rails. I think it is because ruby is the only language(for current moment) which give me money;) So I have experience in writing pure ruby programs, I know all main concepts of Ruby language and every time when I write code I keep in mind best practices;) Most of my projects are coded on Rails, but I have experience with Sinatra too. I efficient with all tools which Ruby developer meet in real life: redis, mongodb, postgresql, mysql, faye, pusher, heroku, git, elasticsearch, sphinx, eventmachine, ajax, bundler. My experience give me confidence that all task which I get, I find a solution and finish them, there is noway to stop on any task. As for my front-end experience it is rather big. I know all basics such as jQuery, underscore, prototypes in pure js, html5, css3, bootstrap(and other frameworks like foundation). But I think that my main position is a backend development. Anyway I know most of the tool with front-end development such as haml/slim, sass/less, coffeescript, etc. As for now I learned a lot about AngularJS but I didn't use it in real projects, so I can participate in project using AngularJS. Also I have an experience with building draw tools using KineticJS. I have an experience to be a team leader/manager. I build a coding team which create a huge travel service under my control. So I can analyze difficulty of an end product, order task by priority to suit product owner wishes. Also as a team leader each week I tried to learn my team something new.  less
