    Lucas Hardy

    Developer specializing in .Net, ASP.Net, and SQL

    United States - Last active: 1 month ago - Tests: 4

    I love programming, and I love providing users with software that solves their problems. My greatest passion is for the lowest levels of a system, not just software itself but also the development process. I get the most satisfaction out of improving efficiency and understandability of a system's core, resulting in a smoother experience for both users and co-workers. I have spent more than seven years developing and maintaining mostly web applications in mostly Microsoft shops. My most-practiced tech skills are thus with ASP.Net, .Net in general (both C# and Visual Basic), various web service protocols such as SOAP for both AJAX and interoperability, HTML/CSS/JavaScript, and SQL, especially Microsoft's T-SQL. I have gotten my hands dirty with administration of the related tools, such as Visual Studio, Visual SourceSafe, Team Foundation Server, IIS, and Microsoft SQL Server, including SQL Server Reporting Services. Other technologies I have passing experience with include Java, Apache web server, PostgreSQL, Python, PHP, and Android. A great deal of my time has also been spent working on the development process. I have authored, implemented, and enforced the complete software development life-cycle, including security and best practices policies. I have coordinated development with other related departments, such as product support, quality assurance, and management. I have prioritized, delegated, and mentored for fellow developers. I have organized and directed deployment of final releases, including documentation and communication with end users and colleagues. If you want a programmer who not only really knows his tools and takes pride in the quality and longevity of his code, but who also knows how to make the work smoother and faster with good communication and good organization, that's me.
