    Experienced Java Programmer, iMacros Guru. Others: PHP, Linux

    Indonesia - Tests: 10 - Portfolio: 2

    I've worked as a Java programmer since late of 2008. I've joined a project to develop a web application that using Spring, Tapestry and Hibernate framework. I've also been involved in a project, and responsible for handling Back Office modules using Compiere (ERP). And many other projects that I can't describe it in here. I also have some experience in the following areas: SQL, HTML, JavaScript (jQuery) and of course OOP. Sometime I 'played' with PHP and iMacros to AUTOMATE small tasks or scrape some websites. I'm also experienced in Linux OS, especially Ubuntu and other distros that based on Debian. I've setup my own VPS to running a Proxy Server using Squid, with multiple outgoing IP addresses. I can help you to install Zurmo CRM on your VPS too.

    Django / AngularJS / Python / Twilio - Plivo Guru

    United States - Tests: 3 - Portfolio: 1

    I'm an experienced djangonaut with experience building and maintaining applications. I'm very good at taking business requirements or a general use case and translating it into code. Technical requirement specifications are so 1999! Here's how my ideal contract workflow goes: We work in an agile manner, where you create user stories, which describe what needs to be done. I'll ask clarifying questions, and then I'll implement the stories. We'll deploy early and often to a staging site where we can collaborate on any adjustments that need to be made. If you already have other django developers on your project, I'll plug in to the team and use whatever branching strategy the team is using (though if asked, my preference is gitflow.) If you're wanting to build a new app, then rest assured it will be built using best practices so that another django developer can join in and participate without a big tutorial. If you already have a project that follows some semblance of best practice (using a pip requirements file, virtualenvironemnts, etc) then rest assured we won't be spending alot of time on "ramp up". In fact, I don't charge for dev environment setup, checking the code out, getting any dependencies resolved, etc. The clock starts when the productive coding starts (and if that doesn't start on day one, we need to have a discussion about why!) Let's build some apps together!
