    Data Scientist

    Spain - Last active: 12 hours ago - Tests: 16 - Portfolio: 7

    Do you have some question that requires a statistical or machine learning answer? No problem. As a data scientist with 15 years of experience, I have the technical knowledge and the communication skills needed to solve your problem and, most important, give an answer that you can apply to your field of interest. What I offer to you is a full data analysis/machine learning stack, including: - Getting and organizing your data. - Selecting the most relevant statistical or machine learning technique for your case. - Applying the technique to your data. - Writing a report that explains every step taken and makes a interpretation of the results. All written with enough technical detail, but that doesn't require a depth statistical knowledge to follow. - Assistance in applying the results to your specific field. I can do all this using any or several of the following: R, MATLAB, Python, MySQL. Everybody can apply an out of the shell statistical algorithm to some benchmark data. But I'm an expert in the tricks needed to apply those algorithms to real data.

    wordsmith

    United States - Last active: 1 day ago - Tests: 3 - Portfolio: 1

    I'm a gifted storyteller, dedicated to helping clients tell theirs. I say this unabashedly and with complete confidence. The proof, of course, is the words. Today, finding the right words is more important than ever, and I strive to under-promise but over-deliver. The name of my company says it all: words-are-my-biz And my philosophy is simple: The right words sell. The wrong words leave sales on the table. WHO AM I? I’m a professional writer living in Portland, Oregon with a lifelong passion for the power of the written word. I’ve written everything from novels to blogs, sales collateral to web content, ad copy to letters, business proposals to sales plans and training manuals. Not to mention a few thousand papers getting my four kids through high school and college. I love what I do. WHAT IS MY BACKGROUND? I bring more than thirty years of sales and marketing business management experience to every project, and by this I’m talking about major corporations to mid-size companies and start-ups, working in fields including software, real estate, law, publishing, advertising and services. I confess to having a particular fondness for high degree-of-difficulty challenges. JUST HOW DO I DO WHAT I DO? By asking questions, listening and considering what I hear, followed by collaborative brainstorming to develop a plan we both embrace with confidence and enthusiasm. As you seek synergy within your organization, I seek it with my clients. It pays huge dividends. The common thread is in finding the way to communicate more effectively, internally and externally, with staff, customers and prospects. The common challenge is in identifying the strengths, weaknesses, opportunities and unique competitive factors confronting each client. HOW CAN YOU LEARN MORE ABOUT ME? Visit my website, home to my novels, blog and publishing company, Old Dog Publishing.

    I'm your personal WordPress Guru, with database, photo editing, and writing skills thrown in. I can set up your site from scratch or jump in to an existing site needing changes.

I'm a native English speaker with an extremely high technical skill level and over 13+ years of website development experience. I am proficient in a variety of coding languages and protocols, with particular expertise in Wordpress, HTML, CSS, PHP, both MySQL/MSSQL databases, and some SEO. I can provide graphic and photo services as well as design feedback. I also have a great deal of experience in writing and editing, both technical and non-technical materials. I am very good at communicating both with technicians/engineers and non-technical clients to translate needs and desires into workable engineering and web-based solutions.

Your projects will be completed professionally and to your complete satisfaction. Thank you for your consideration! **NOTE** Please disregard the number of "Projects in Progress" that ODesk displays; I have a number of clients who use my services heavily for awhile, but then need nothing for weeks. Rather than starting a new contract each time, we pause the contract, but this still displays as an active contract. Please contact me to determine my actual availability.
