Charleson R.

Charleson R.

Experienced Filipino Web Developer

Philippines - Tests: 7 - Portfolio: 16

For 7 years, I have been in touch with different companies and clients who want to have a website built from the ground up. I have developed a wide range of websites ranging from social media related sites, websites designed specifically for mobile phones and tablets, e-commerce websites like online apparel store sites or real estate sites, websites for small businesses or startup companies. I mainly use PHP, HTML, JQUERY and MySQL when building these websites. My choice of out-of-the-box CMS to use is DRUPAL because this is a very flexible and well-built CMS and can be developed in many different ways. When it comes to work, I make sure that my clients are satisfied with my work so I really give a lot of importance to the quality of code I make and it's efficiency and usability. I am very open to many possibilities and take into consideration what my clients or employers want in their website. I give my best opinion whenever necessary in order to improve the development that may later on benefit me and my clients. If hired, I make myself always available for the client whenever they have some questions or additional clarifications. Long term relationship with my clients is a proof that they are really satisfied with my job and work efficiency. I am a teamplayer and I can work well with other people, I respect their opinions and points especially if they give better points that may improve work development. I can also work without much supervision as I always understand first clearly what needs to be done and how it should be done.

C++ Designer and Optimizer

United States - Tests: 23

I'm a self taught programmer with experience largely in C++, but also in Haskell, PHP, Pawn, Lua, and NASM. I have a full decade of work in game modding communities, and have worked on linux patches, game engines, and the intricacies of the C++ compiler and object model for many years now. If you need to squeeze more speed out of your code, or come up with expressive and elegance solutions to unusual or involved problems, that's what I excel at.

Jay Good

Jay Good Agency Contractor

Sr. Web Developer and DBA

United States - Tests: 3 - Portfolio: 21

I have been developing software and working with databases for the past 16 years. I design object-oriented, tiered applications and write code in PHP, C#, and VB.NET. I have also written applications in C++ / MFC / Win32 as well as VB 6.0. I design and administer databases in MySQL and Postgres and excel at writing triggers, functions/procedures, and views. I have also worked with SQL Server and Oracle. Over the past couple of years, I have moved into being a PHP developer with a preference for the CakePHP 2+ framework (though I also know Zend 2+). I truly believe that PHP, HTML5, and CSS3 are the future of the software world. Since PHP was specifically designed for creating web pages, it only makes sense to use it for web development, especially now that object-oriented features and other modern functionality have been added to the code base. I hold a computer science degree (1998) and have several years of practical experience. I have been using the .NET Framework since the Visual Studio .NET Beta and write .NET code primarily in C# and VB.NET. I prefer to work with applications that follow an n-Tier architecture along with object-oriented concepts such as inheritance and abstraction but will work with just about anything. I have vast experience using C++ and the Microsoft Foundation Classes along with the Win32 API. Other languages/frameworks include PHP, LINQ, Regular Expressions, VB 6.0, and straight C. I have been designing and administering SQL databases since SQL Server 7.0. Software Engineers tend to be bad DBAs but I believe that I am the exception. Database concepts such as normalization/denormalization, primary/foreign keys, and check/default contraints are not new to me. Whether it be T-SQL or PL/SQL, I also excel with database programmability, such as triggers, procedures, functions, and views. File organization and usage, backup and maintenance, and database efficiency are also strengths. I currently primarily use PostgreSQL 9+, where available and MySQL 5+ where it is not. Other databases include SQLite, Oracle, and yes, Access (95 on up). During the past 16 years, I have created and maintained custom line-of-business Windows applications, with a focus now more on Web applications. These have included applications for law enforcement, 911 centers, jails, retail businesses, nursing homes, trucking companies, charities, talent brokers, community/group sites, and e-commerce. I have also designed and coded applications for GIS mapping systems and some data mining and sharing initiatives. I have created custom TCP/UDP servers and clients for low-bandwidth mobile applications. I have worked with O/R mappers such as LLBLGen Pro and are used to using entities in data layers rather than reading/writing data directly. Where applicable, I prefer to use the MVC (model-view-controller) mantra, where manipulating, presenting, and controlling the data is abstracted out. I am used to using source control systems such as Git, SVN, Vault, and SourceSafe. I excel at Web Applications, Windows Forms applications, Windows Services, records management applications, interfaces with third-party APIs, integration of systems, and middle tiers such as the business or data layer (just in case you already have a web application but need the back-end to work). Preferences/Specialize in: Web Applications Records Management/Business Applications Database Design/Administration Windows Services Back-end Work (business, data layer, facade) Windows Forms Applications API Programming Integration of Systems Data Mining/Conversion Programming Languages: PHP 4/5 C# VB.NET C / C++ Java VB 6.0 Databases and Languages: MySQL PostgreSQL SQLite SQL Server T-SQL Oracle Database PL/SQL Access DataFlex AcuODBC Libraries/Frameworks: .NET LINQ LINQ to SQL LINQ to XML Regular Expressions WPF MFC Win32 API ADO.NET ADO DAO/Jet Concepts: Object-Oriented Programming n-Tier Architecture Service-Oriented Architecture Normalization/De-normalization Primary/Foreign/Unique Keys Check/Default Constraints Database Programmability Tools: Visual Studio SQL Management Studio Eclipse PhpStorm LLBLGen Pro VMWare Microsoft Office (Word, Excel, PowerPoint, Outlook) TextMate DbVisualizer Active Reports Crystal Reports Iron Speed CodeOnTime Source Control: Git SVN SourceSafe SourceGear Vault Web Programming: CakePHP 2 & 3 Zend 2+ Silverlight HTML, HTML5 CSS, CSS3 JavaScript WCF SOAP REST JSON XML XSD Web Browsers: FireFox Chrome Internet Explorer Safari Operating Systems: Windows Mac OS X
