    Security-focused IT Admin & Developer

    United States - Last active: 9 days ago - Tests: 1

    I worked as senior software developer for a high-tech security corporation for 2 years (and still do consulting with them) and have been a developer for 6 years. I was responsible for their security audits and testing of their SaaS apps. I developed many cryptography-focused applications and wrote dozens of integration projects for cryptographic hardware tokens. I'm familiar, and up to date, with modern hash schemes (ie. SHA2, MD5), symmetric/block algorithms (ie. AES), and asymmetric algorithms (ie. RSA) and best practices. I practice secure programming in all of my projects and always follow best practices to ensure the final result is of the highest quality. I'm well-versed in PHP, HTML5, CSS, JavaScript (including jQuery, Angular, and Node), Bootstrap, PhoneGap / Cordova, WordPress, and ASP.NET. I also run a security-focused blog (https://joscor.com) and provide security audits for large state agencies in the area.

    Thomas Weidman

    Developer (PHP, ColdFusion, C#, .NET, MVC3, HTML5, jQuery, Sitefinity)

    United States - Last active: 3 days ago - Tests: 3

    Since 1998, I have done a wide range of web development and have used many technologies (C++, Perl, VB, VB.NET, C#, ASP, ASP.NET, ASP.NET MVC2, ASP.NET MVC3, SQL, PL SQL, T-SQL, ColdFusion [CFML], PHP, ActionScript). I have also used many tools from Flash, Fireworks, Photoshop, Dreamweaver, Eclipse, and Visual Studio. My core skill set lies in problem solving and creating solutions to solve problems in the most efficient (time, budget, and quality) way. I enjoy development and do so in my free time. I use that time to explore new topics that look interesting and to expand my knowledge on existing topics. I have a unique work experience and understand not only coding but also network and server implementations (being a system administrator). I have experience integrating technologies to fulfill requirements or solve limitations of technologies. An example of this I can provide is a solution I did for a client. The solution involved ColdFusion, SQL Server 2005, and ASP.NET Web Services. Due to specific security requirements and limitations of interoperability of ColdFusion 7 and ASP.NET I developed SQL Server CLR Functions and Procedures that invoke web services and return structured data to ColdFusion. From a CF developer perspective all you do is call a stored procedure or execute a cfquery call. The DBMS server does the rest and because it has the ability to use the .NET language I was able to invoke custom services that had very specific security requirements. This solution has been in place for three years now and has not had any issues with this method. I have also used different technologies to handle things like encryption for PCI compliance. I worked with a client to build a custom transactional processing system that utilized C++, Java, SQL Server, PHP, and ColdFusion. The end result is a distributed secure system that handles all payment processing for this client (Web and Internal). This solution also required an understanding of Firewalls, IDS, and how to combine technologies so they would work together seamlessly. If you're looking for a developer who can research options, architect solutions, develop and document, I am an excellent choice and look forward to working with you.
