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

    United States - Last active: 5 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.

    Quant Finance, Trading Strategies, Algorithms, C#, Python, MATLAB

    United States - Last active: 1 month ago - Tests: 2

    If you want to create a trading system, run a statistical analysis, develop a pricing model, build a financial GUI, or find a pattern in a sea of data, I may be the guy to help. I work primarily in MATLAB, C#, and Python. On the finance side, I'm a CAIA Charterholder, with an Economics degree and experience at McKinsey & Company. On the technical side, I hold degrees (with honors) in Engineering, and worked at a number of California tech companies through the 1990's and early 2000's. Since 2008 I've focused my work in the field of computational finance. Recent clients have included: a Swiss proprietary trading desk (Energy Futures), a Canadian hedge fund (Currencies), a US asset management firm (Equities & Bonds), a US portfolio consulting firm, a US aircraft manufacturing operation, and several others. For those clients I have developed, backtested, and deployed alpha-seeking trading strategies, automated execution algorithms, portfolio optimization models, user-friendly GUI tools. Techniques have included machine learning algorithms, classifiers, feature detectors, digital filters, matrix-based models, and concepts borrowed from detection theory and signal processing, along with various technical analysis indicators. I've worked with many financial platforms and data feeds: Deltix QuantOffice (C#), CQG API, Bloomberg, Interactive Brokers API, MultiCharts (PowerLanguage), MultiCharts.NET (C#), TradeStation (EasyLanguage), FIX (HotspotFx), ITCH (HotspotFx), etc. I can integrate other systems with MATLAB or Excel where there's an advantage. I've created C/C++ .mex files, VBA macros, Java/MATLAB integration, MATLAB/Excel integration. I've been programming in MATLAB since 1990, and can sometimes get it to do things that others can't. I can also translate or port a MATLAB application to other languages, especially Python or C#. I'm located in Southern California. For clients located within 2 hours, I can drive to meet you (sometimes same day, schedule permitting). I'm also happy to work remotely. I'm a US Citizen and have held a security clearance, though it is no longer active. The foundation of every successful project is good communication. If you have a project that needs to be done well, then let's communicate!
