SQL, Delphi, DB/Server Admin, Joomla, Google App, Stocks Screener


Surabaya, Indonesia


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 ... moreby 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. In summary, my expertise are: - SQL optimization, database maintain & administration such Oracle, MS Sql, MySql, PostgreSql - App creation, rewrite and modification with Delphi, Access, VB, C, OOP - Maintain & build websites with Google App & Joomla - Server remote administration - stock screener query builder less
