    I am the best in Web and Client/Server development using PHP, MySQL, Lotus Domino, ASP Classic, VB. As an IT project manager for the greater part of 12 years, I have thus perfected my skills in PHP, Lotus Domino, ASP Classic, HTML 4.0, JavaScript, and CSS 2.0, among others. As a developer, I find out the exact needs of my client and hold myself accountable for time management, cost-efficiency, conflict resolution, quality assurance, and above all, client satisfaction. My unquenchable thirst for knowledge, coupled with specialized experience in the field, makes me your ideal developer. I am self-motivated and have never missed a deadline. Over the past decade, I have been developing applications using Microsoft ASP, Visual Basic, PHP, MySQL, SQL Server, and Lotus Notes, majority of which are deployed over the web and are rendered cross-browser compatible. Such applications were developed either during my tenure for my employers or through referrals from clients or contractors that require my expertise in web development. My experience includes, but is not limited to, PHP, ASP, MySQL, SQL Server, HTML 4.0, CSS 2.0, Ajax, JavaScript, VBScript, Visual Basic for Applications (VBA), Lotus Domino, object-oriented programming (OOP), and HP LoadRunner.
