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

    United States - Last active: 23 days 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 I'm a US Citizen and have held a security clearance, though it is no longer active.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!

    Spreadsheet Guru and Workflow Specialist

    United States - Last active: 1 month ago - Tests: 3

    When I was 11, my parents showed me how to use Excel to track my trading card collection. Today, I'm a spreadsheet ninja. I know pivot tables like the back of my hand, I can script you out a macro in a matter of hours, and I can nest functions together in ways you've never thought possible. Big words, sure, but I back it up. I have built reports, ad hoc and repetitive, that have gone as high as the board of directors of Fortune 500 corporations. My VBA-enabled smart forms are used by front-line operations personnel, and are robust enough to handle transactions from any end user. I also have many years of experience developing business procedures and workflows. I can map out a workflow and easily identify where efforts are being duplicated or wasted. My expertise in automation has helped large companies reduce their staffing costs while reducing manual error rates and increasing overall productivity. As a business person who "speaks tech", I make a fantastic liaison between end-users and developers, thereby reducing complications during the business application development process, and making sure that the product you need is what is actually delivered. I also know a thing or three about coding and web design. Self-taught mostly; I took the intro to Comp Sci courses in college, but I picked up most of my chops modding video games and automating repetitive tasks at work. I've also taken a few Codecademy courses to round out my knowledge base. I've never spent too long in any specific language, so I actually think I have a better understanding of how computer science works than a dedicated coder who stays in one language all day does. In essence, a lot more breadth than depth. Languages I know today and are comfortable taking on work for include C/C++/C#, Java, Python, HTML, CSS, and PHP.

    Over the past years I have developed desktop apps, web pages, spreadsheets and databases for many private clients.

I have only recently started using oDesk to find work but am hoping to build my reputation quickly.
