    Software Developer, Excel/Add-in Expert/C# Specialist.

    Canada - Last active: 6 days ago - Tests: 1 - Portfolio: 4

    I have a strongly-developed technical education, coupled with a decade of sales and service experience, and three years immersed in intense software development projects. Programming is my art form. I do it simply for the sake of doing it. I don't stop until I am fully satisfied that I am providing you with my best possible product. When developing software, I take a "step back" and look at the "big picture". I ask myself, "what are we trying to accomplish here?" before writing (or changing) a single line of code.

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

    United States - Last active: 16 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!

    C-Level DNA - Angel/VC Hacker - Business Growth Strategist

    United States - Last active: 1 day ago - Tests: 10 - Portfolio: 2

    Every successful business begins with one person and a vision. Inevitably, that vision must segue to a strategic plan and focused execution. This is a space I've successfully lived in for over 20 years. I assist in developing Business, Strategic, and Operational plans. I help prepare companies for raising capital, and where practical, provide introductions. I help recruit top management. My strengths lie in business planning, short-long term strategies, and sourcing talent. I can take role as an advisor, collaborator, and/or team member to execute plans and strategic initiatives. I help clients deliver positive results to their bottom line, take them from "marginal to viable", and often I help position them for a high(er) probability of an 'exit' when the time is right. I help deliver organized, business-focused narratives and messaging that inform internally as well as externally to vendors, clients or investors. Whether a start up, early stage, or middle market, I approach every engagement in the same manner. I first establish an understanding of the business as it exists today. I review the current business structure. I peel back the layers to clearly assess the business, financials, market dynamics, team, and strategy. I look at the business in its current iteration and then sit down with you to discuss both the 'big picture' and what the goal line looks like to you. Early on, we may well reach a point where I share less-than-good news; There's still work to be done. But it is at this point where I see clients reach a level of cognitive realization, who understand and agree with my position or feedback, and that's where things can start to get exciting. Engage me on an initial consultation (no fee) regarding your business goals and strategy. The outcome of that dialogue will tell us both if there's a fit and whether it makes sense to engage in a mutually beneficial relationship to advance your goals. Michael

    Expert C#/.NET Developer Newly Returned To Upwork. First Hire Discount

    United States - Last active: 2 months ago - Tests: 21 - Portfolio: 8

    If you don't have IT or software project experience, please don't contact me (unless you're a trusting adventure-seeker :) Bring Your Own Designer! IT Industry Knowledge Includes: - Best-practice Design & Implementation - B2B & B2C e-commerce - Systems Automation - BPR/Workflows- SaaS/Web 2.0 - Cobranding Vertical Industry Knowledge Includes: - Real Estate, Construction and Manufacturing management systems - Insurance (workflow) - Digital Media (distribution and conversion automation) - Healthcare (data collection & management) Some Background Information: - I have designed, implemented, and administered a wide variety of m$ft infrastructures, operating systems, servers, and applications for over 10 years. - I manage Apache, NFS, Samba, Asterisk, Bind, and other services on Red Hat-esque (CentOS, Fedora) servers. - I have been working with .Net since it was in beta. Before getting into C#, I used VB.Net for several years. - I've been writing enterprise-scale business and data layer code for over 4 years. - I've been managing and programming Microsoft SQL Server since version 6.5 (and am up to date on 200X), and Microsoft Access for many years. - I've worked with MySQL/SQLite and PHP (4+) as a hobbyist for several years. I can perform most any task required to update an existing site, but am probably not suited for a new development project in PHP.- Prior to .Net I programmed in traditional asp using VB Script, COM & DTC. - I manage my own dedicated windows 2k3/8 servers with multiple running applications and servers. - I have experience with a wide variety of third-party components and controls., and can assist in integration, middleware, queuing services, etc. - I'm not a graphic designer, and prefer to leave site layouts and graphics to someone more suited to that type of work. I am ok with creating basic layouts (and working within the popular graphics editing programs), but for a polished look, I'll either work with your designer or contract to another party on your behalf to acheive the look that you're after. Getting What You Pay For: Sure, you can find loads of developers here and on other similar service sites at a fraction of my rates. Why would you pay me? - I will stand behind my work. If you're unhappy, we'll fix it. - I will not charge for time spent figuring out how to solve general technical problems. If I don't already know how to implement a relevant solution, I will spend MY time researching and figuring it out. We're supposed to be professionals, and if we don't understand what the problem is, we shouldn't be charging you. Besides: each time I solve a unique problem, it makes me more effective; for you, me, and my next happy client! NOTE: Most of my work is done for companies' internal intranet, operations and LOB applications. I've added a few items to the portfolio, but please ask me about the other work which I can't showcase. While I'm often bound by NDA/Confidentiality agreements, I can explain more about my background in a general way than is illustrated publicly.
