    Senior developer, Project Manager

    China - Last active: 6 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.

    Spreadsheet Guru and Workflow Specialist

    United States - Last active: 1 month ago - Tests: 3 - Portfolio: 1

    When I was 11, my parents showed me how to use Excel to track my trading card collection. Today, I'm a spreadsheet ninja. I know pivot tables like the back of my hand, I can script you out a macro in a matter of hours, and I can nest functions together in ways you've never thought possible. Big words, sure, but I back it up. I have built reports, ad hoc and repetitive, that have gone as high as the board of directors of Fortune 500 corporations. My VBA-enabled smart forms are used by front-line operations personnel, and are robust enough to handle transactions from any end user. I also have many years of experience developing business procedures and workflows. I can map out a workflow and easily identify where efforts are being duplicated or wasted. My expertise in automation has helped large companies reduce their staffing costs while reducing manual error rates and increasing overall productivity. As a business person who "speaks tech", I make a fantastic liaison between end-users and developers, thereby reducing complications during the business application development process, and making sure that the product you need is what is actually delivered. I also know a thing or three about coding and web design. Self-taught mostly; I took the intro to Comp Sci courses in college, but I picked up most of my chops modding video games and automating repetitive tasks at work. I've also taken a few Codecademy courses to round out my knowledge base. I've never spent too long in any specific language, so I actually think I have a better understanding of how computer science works than a dedicated coder who stays in one language all day does. In essence, a lot more breadth than depth. Languages I know today and are comfortable taking on work for include C/C++/C#, Java, Python, HTML, CSS, and PHP.
