    Spreadsheet Guru and Workflow Specialist

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

    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.

    Information Technology Consultant

    Uruguay - Last active: 16 hours ago - Tests: 4

    My objective is to help people understand what technology can do for them. The past year I've been deep diving both Odoo (v8) and openerp (v7), doing extensive customizations on the base modules (especially the accounting related modules), plus developing a custom tailored application with over 2000+ total programming hours, serving as the lead programmer and technical analyst. I'm a top of the line programmer, with varied experience, ranging from web programming, server infrastructure and databases, up to openGL based games, scientific computing and machine learning. While I'm technically proficient, the main attribute that differentiates me from most programmers is that I dig deep when thinking about businesses, using my skills as leverage to help clients make more money. Drop me a line at bfigaresvillalba@gmail.com if you want to discuss a project.

    First things what I'd like to say is that I work only on projects where you can provide me access to your resourses. For working "on blind", theory, suggestion or any other form of work where I can't see results... simply forget it, I won't work with you. Teamviewer is too slow for working, so only in some cases I'll accept to work on that way. My skills: Languages, envirements and projects C - POS terminals, Linux shared libraries, Cryptography, Protocols; Java - Cryptography, Protocols, JDBC, Ibatis; C# - Amazon MWS; Oracle PL/SQL developer; PostgreSQL + migration of projects from Oracle to PostgreSQL; Python - by need for scripts and help tools. Linux knowledge. Experience in payment industry. Capable to organize your data into database.
