** Skilled professional software engineer (cs & s/...

United States - Last active: 03/16/2011 - Tests: 6 - Portfolio: 3

With 17 years experience in software engineering and development, I've worked on a diverse set of projects. I consider myself a life-long learner and have never hesitated to dive into becoming an expert in new domains. I've worked on projects in academia, for businesses, defense contractors, government laboratores in several countries and also many of my own varied projects. As of May 2013 - I'm available 20hrs/wk (possibly up-to 30). Some areas of expertise include: - Distributed systems & architecting for the Cloud - Web Applications (Ruby & Rails, LAMP - Linux/Apache/MySQL/PHP); AJAX - jQuery/Javascript; web-service APIs (XMLRPC/JSONRPC/REST) - Relational & Object Database Design - Simulation: physics simulation, 3D graphics (OpenGL, OpenSceneGraph) - C++ desktop applications (UI, libraries, components) - Bioinformatics (Biolab Matlab-like bio environment - Java/C#/.NET/Python) - Networking (protocol design; wireless; TCP/IP; HTTP and related technologies) - Embedded systems (hardware system design, construction & programming) - Operating System design and implementation - Language design, interpreter and compiler construction - Human Computer Interaction (HCI) - user interface design & implementation (X11, Interviews/Fresco, Qt, Swing, AWT, Winforms, GTK+) - Robotics: AI, Vision, Path planning, Inverse Kinematics - Hardware: Sensors, VHDL, FPGAs Most of development has historically been in C++, but in recent times I've favoured C#, Java or Ruby. For web applications and services I prefer Ruby but also have experience in PHP. Over the years I've used many languages and can pick up new languages and their library frameworks quickly. I've also designed languages (upto the complexity of C++) and written interpreters and optimizing compilers (so I've not met a language feature I'm not well versed with). I'm a good communicator, proficient at technical writing and have published many papers in peer reviewed journals and other publications. I'm most interested in working on web sites/services, particularly where complex distributed systems involving interacting databases are concerned or in the area of virtual reality, 3D graphics and simulation systems (including cutting-edge 3D game platforms). However, in general I'll find anything challenging interesting to work on!

Do you need help turning the unstructured web into meaningful data? Example Applications * Crawling and extracting data from websites * Analyzing Twitter data to find people that are interested in your products or services, or people that are talking negatively about your competitor's products * Correlating social media sentiment with stock pricing * Organizing documents from a local LAN for a lawsuit * Leveraging Machine Learning, Artificial Intelligence, LSI and Bayes Theorems to analyze "big data" and find trends Over the last 3 years, my company and I have built core expertise in crawling, data extraction, classification and machine learning. And, as we finish building our new marketing analytics commercial application, I'm looking for 1 to 2 projects that would fit and be synergistic with our current capabilities and development focus. Advantages of TEMPUS Group 1) Cost. In exchange for me being "particular" about the work we do, I'm offering a dramatically discounted rate from me and my team (over 60% off) of what we currently charge our existing customers (rates start at $125/hr). And, you get the benefits of working through ODesk. 2) Integrity and Pedigree. I have a history of execution and delivering value. In the past ventures I've been involved with, I've returned over $400 million on $65 million in investment. I understand what is "worth doing" and I won't burn hours if it doesn't help you achieve your goals. 3) Expertise in our Core Discipline. We are very focused on this particular need. If you want a website built, you're best bet is to hire someone for far cheaper. However, if you have crawling/data extraction/enrichment needs, we're focused and can help you deliver this faster than you thought possible. 4) US-based with US-based execution standards. You will most likely work with me (William) daily, and you will have my email, phone, cell phone, Skype and other IM so you can reach me anytime. And, I usually answer my phone unless I'm hard at work on a project. ODesk is about cheaper labor. That's true. But, isn't the total cost the true metric? We won't waste your time. We won't waste your money. And, if we can't get the job done, we'll tell before we commit to the project. Reach out to me, I'm happy to talk about your needs and see if we're a fit.
