    Senior developer, Project Manager

    China - Last active: 11 days ago - Tests: 9

    Professional and hobbyist developer, with over 15 years of actual development under the belt and 6 years in 'hands-on' management positions (as engagement manager in a consulting firm and then as a CTO in a web startup). My technical experience ranges from desktop (C/C++/C#/Java/VB, scripting in Python/Ruby/VBA), embedded (PIC, ATMEGA, ARM), web (PHP, Ruby on Rails, JS/Coffeescript, HTML5 and some understanding of web design principles and UX construction) and ERP/Business Intelligence (SAP BW, QlickView). These days (2014), I am mostly doing web dev (front-end/back-end) in Ruby, Python and CoffeeScript - they allow very quick iterations and cutting through tons of boilerplate to get to a MVP as quickly as possible. My skills in C/C++ are a bit rusty, but I'll gladly dust them off for an interesting project :) I read Java and C# and don't mind using them as external dependencies, but I do not enjoy working with those. As for my management experience, I have been leading small and large engagements (up to 2 millions EUR) in offshore settings (India, China), both on-site and remotely I feel like I have a good understanding of the communication and management challenges involved in freelancing. As your contractor, I see myself adding value by challenging your requirements, helping you define clear specifications and, if the assignment is large enough to need more than myself as a developer, I can help you screen out other offshore resources and simplify your outsourcing experience.
