    Experienced JavaScript developer - NodeJS, Angular, Backbone, MongoDB

    Romania - Tests: 13 - Portfolio: 5

    I love web development, and I do web development for a living. I can bring value to your project, by applying the experience I've earned over the years along with the latest methodologies in the web development field. You can count on me to be an honest person, and I will tell you upfront what are the challenges that we might face while working on your project, and you will know very quickly if there are any major issues, or if there are pieces of functionality that are better re-written, rather than patched. I am: * Fluent in JavaScript and related front-end and backend technologies.(HTML, CSS, NodeJS etc.) * Proficient with Jira. * An Agile methodologies enthusiast -- I've used both Scrum and Kanban workflows. * More than happy to use spreadsheet applications to get organised. * A Markdown user -- I use it to generate documentation and rich text in general(email, etc). * Currently learning Lua -- http://www.lua.org/ -- and fiddling with Arduino. * Documentation advocate -- I like well documented code, processes, and workflows. * Advocating for stronger human interactions, which I highly value in whatever I do. * A Python/Bash user -- various command line tools, automation scripts. * A firm believer of the fact that one should choose the right tool to get the job done, not the tool that they like. On a side note, I've worked on Flask and Django projects, I use Bash scripts sparingly, I've used Vagrant and Docker for environment virtualisation/replication, I'm familiar with Git and SVN workflows.

    Trading System Development using Amibroker

    United States - Tests: 1 - Portfolio: 2

    System developer, consultant and part time trader at InStat Research. Programming is done with Amibroker's AFL mainly although various scripting languages, C++, C# or Python have also been used. We can program basic indicators, trading systems, and various automation tools, such as automated trading or automated optimizations. We also develop extensions for Amibroker in order to automate manual tasks (i.e. updating databases) or to execute trades on other platforms. I have swing traded and daytraded the markets for years, including ETFs, stocks, bonds, forex, futures, options, mutual funds and know if a system just looks good but is non-tradeable because of liquidity, data or other problems. Our quote will be the maximum we will charge unless the client introduces new criteria once the project has started.
