Indonesia - Tests: 4 - Portfolio: 3

I have been working as professional developer since 1995, at the first the projects I did mostly was building database application using Delphi and SQL. Now besides developing application, I also build websites and administrate database and server remotely, and use my past experiences to give solutions in the projects. Joomla is one of my tools in building website, of course accompanied by the good third party components. Sometimes for a better result, adding codes by using PHP and Java script is needed. For small or personal company which need to have the best and free hosting company for their websites, for me that solution will be Google by using the Google App along with their good services. By this solution, the only payment needed usually is for the domain name only. In this one last year, I do stock trading myself and using stock screener query in replace to MSN Deluxe Stock Screener. This is a very useful tools to help people to find the best stocks in their trading.

API Specialist, laser-focused on PHP and MySQL

United States - Tests: 1 - Portfolio: 5

I'm a Top API specialist with >2500 hours and >$150k earned on Elance in my first 1.5 years here (joined Feb 2014). I've already established longterm work relationships with several clients now but am always interested in meeting new clients and lending a helping hand with my excellent problem-solving skills, fast and accurate communication, and acquired API knowledge base. My top skills include: - 10+ years with PHP (class based) - 10+ years with MySQL (2 years architecting from scratch) - 4+ years with Linux servers, including SSH command line - 2 years with Git - 1.5 years doing heavy-duty, complex API integration I think I'm best suited as a backend developer handling server-side communication. I have a solid amount of frontend experience with HTML5, CSS, jQuery, and Javascript, but I prefer to spend my critical thinking time on solving data flow-related puzzles behind the scenes. To-date, I've worked extensively with clients from the following fields: 1. Restaurant delivery service - created portals to receive and integrate orders through multiple 3rd party APIs 2. Wall decal business - became the primary manager of a dedicated Admin server with full Amazon MWS capabilities 3. Graphics supplier for physical products - built an entire scheduling and file internal system from scratch and took the entire company of 60+ employees online, cutting out the vast majority of on-paper communications 4. Multi-million dollar landscaping business - connected multiple 3rd party services together with bidirectional syncing and many-step-processes-with-a-single-button-click logic to streamline the flow of bidding, projects and accounting I continue to work with all 4 of these clients and have also done another 20+ projects outside of these on Elance/Upwork. I look forward to working with you and am very confident that I can make a difference!
