My name is Gayuh Hikmawan. I am a full-stack programmer for mobile, web & client/server applications. Proficient in Android, PHP + MySQL, Microsoft .NET + MS SQL Server, C#, HTML + Javascript, Visual Basic, Java, and VBA (MS Office macros), I also write technical documentations and do some graphic design works, primarily UI designs and image editing. Fluent in writing & speaking English, I frequently do translations between English and Bahasa Indonesia (100% manual, to achieve human-quality translation). I sometimes also write articles and reviews for blogs and forums. I am an Identity-Verified freelancer. That means my real identity has been verified, giving employers additional assurance on my commitment to doing business with full integrity.

He dug into several areas that were related to get a complete understanding of my needs and wound up making several suggestions which I told him to incorporate that made the resulting work EXTREMELY more practical and easier to integrate into the master project. His command of English made communication easy. He should be at the top of your list for work in his areas of expertise because he can get it done right and quickly.”
