    Security-focused IT Admin & Developer

    United States - Last active: 8 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.

    Neoload certified , load Testing, jmeter, data scrapping

    India - Last active: 24 days ago - Tests: 1

    For the last 5 years, I am working dedicate on performance Testing using Jmeter and Neoload. Moreover, I have good expertise in Data scrapping using Jmeter. I have tested the performance of many applications till now. Also, I have strong experience in developing vbs scripts for Excel Automation and for Database connection to fetch the test data for the Load test. For the last 9 months, I am working on security testing using BURP. I have found many issues that are related to Broken Authorization, XSS attacks, SQL injection, etc. Testing performance of the application does not means to provide with the details of the time taken by the various transactions only, but it also includes the process of finding the different issues that can affect the application when it will be accessed by the end users. i.e the analysis of the results. While working on different projects, I have a good experience of creating the performance Testsuite as well. I have worked on two tools; Neo load test & JMeter. Neoload is a Licensed tool (working on it for the last 13 months) while JMeter is an open source tool. Experience of testing FLEX and sileverlight applications Experience in the result analysis part of the load test. I have also used perfmon on the server side (DB & Web server) to measures the different performance counters and then checking which counter is going outside bounds. Experience with SVN Experience with Javascript & VBA

    Thomas Weidman

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

    United States - Last active: 2 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.

    Senior Dev: Perl/Catalyst/Moose/DBIC/NoSQL+AJAX/jQuery, shell+sysadmin

    Ukraine - Last active: 1 day ago - Tests: 19

    Seeking opportunities in Perl oriented (Catalyst DBIC preferred) application development, shell and perl scripting, and BSD/Linux administration projects - to build sites and setup servers for your business or pleasure.In my mind, LAMP more often reads as LASP - Linux, Apache, (any|no)SQL, Perl - of course, with Catalyst, Template Toolkit and DBIx::Class/KiokuDB in pair with some RCS (git is preferred, but subversion, mercurial and others also possible). And of course, all can be integrated with AJAX libraries such as jQuery, Prototype, MooTools and other to create Web2.0 apptications.Great knowledge of regular expressions (regexp). Have real experience with MySql, Postgres, Oracle, CouchDB, LDAP, also worked with CPanel, Plesk and Ensim. And of course, have experience with Apache, SMTP (exim, postfix, sendmail), IMAP/POP (Cyrus, UW, Dovecot), firewalls (bsd/ipfw and linux/iptables), Samba and misc ftp and proxy solutions.I can work well as alone and as a team member.
