    I am Miguel Rodríguez, a freelance developer from Caracas - Venezuela with Computer Science background. I am a persistent and goal-oriented person who tries to make the best use of the resources. I am positive, proactive and motivated enough to set a goal with the intention to fulfill it. For the last 3 years I have been developing web apps related to CRM/ERP or any other administrative/organizational purpose on PHP/HTML/JavaScript, however, I would love to be involved in a video game development. I have always thought this: "The people are the one who use the technology and not otherwise." I do not feel as if I was bound to a specific technology, any professional should deliver a great job no matter what technologies are used. Describing me in few words, I am honest, thoughtful and persistent. I try to be kind whenever I can, I always say the truth, even in situations that could affect me, I take promises very seriously, so, I don't promise that easy, it would be unfair to say that I am a perfect person, like any human I make mistakes, and, when it happens, I recognize them, I apologize and I try to learn from them, I usually don't react violently and I have no criminal record.

    I love to develop in Django. I can define myself a Senior Programmer and a Technical Leader, specialized in projects that uses Python/Django as backend and Angular JS as frontend. The two frameworks connected through methodologies like RESTful calls, Websocket (socket.io) or traditional HTML server side rendering. As corollary I have robust knowledge of Linux servers management and Python application environment deployment. My particular experience makes me capable of autonomous development on small projects plus a great integration skill with teams on larger ones. An in depth knowledge of all development problematics makes me a competent Project Manager and technical advisor. ✎ Languages & Frameworks - Python : Django - PHP: Yii ☉Databases - PostgreSQL - MySQL, - SQLite, - MongoDB ☺ Frontend - Javascript, JQuery, Angular.js - HTML, CSS - Twitter Bootstrap ♨ Servers - Amazon EC2 - Heroku - Linode - Gentoo - Ubuntu - Fedora Core  less

  • Sr. Web Developer and DBA

    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 framework. 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. Other databases include PostgreSQL, MySQL, Oracle, and yes, Access (95 on up). During the past 16 years, I have created and maintained custom line-of-business Windows applications. These include applications for law enforcement, 911 centers, jails, retail businesses, nursing homes, and trucking companies. 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. If you have a SQL Injection problem, I can probably fix it. 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 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 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 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 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  less

Security is one of my strengths - anything I develop, I make sure to defend against known exploits and vulnerabilities and I have won first place in my state in a computer security competition. I also have a moderate amount of experience with graphic design, and scripting and writing command line applications for both Linux/UNIX and Windows systems, often for data processing, web scraping and generation of HTML and/or PDF output.  less
