    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 stockfetcher.com 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 - StockFetcher.com stock screener query builder  less

With further demonstrable experience of managing teams in excess of 30 members including local hire and remote resources, together with all aspects of annual performance appraisals, and contractor negotiation, with an excellent understanding of the latest ITIL methodologies for ITSM.

I have a strong mix of corporate enterprise, SME and entrepreneurial experience, and to expand on that, my experience has afforded me the ability to learn the complex matrix management structures and business models which predominantly gained within Global Financial Services Industries (Investment Banking and Global, Corporate and Specialty Insurance). Where conversely some of my most recent and earlier career experience was based in one of the most competitive customer service industries, and to achieve success in this, I had to be flexible to market conditions, so that I could maintain strategic focus so as to continually meet my financial targets. The combination of my career experience has provided me with the opportunities of working in USA, Belgium, France, Spain, Gibraltar, Abu Dhabi and secondments to Brazil, Mexico and APAC, for projects that I was either managing or transferring to local piers and latterly I had responsibilities for USA, Germany, Italy, Switzerland and Denmark.
