    top-grade, full scale software developer

    Hungary - Last active: 3 days ago - Portfolio: 3

    I'm an expert high capacity scraper builder. (Amongst some 12 other major areas of operation in IT and software development.) Most likely the best of the few top scrapers on Upwork (and Elance). I can write software in Phyton, Javascript, VB.net, C#, C++, Java, PHP, VB6/VBA and other scripting languages. More than 15 languages. Also, I have intermediate web programming and web operations knowledge. (Ie. setting up an optimized server farm with up to 5000 servers.) My scraper softwares extracted far more than 1 billion (!) data rows since Feb 2008. I wrote more than 2 million (!) lines of code since 1986. I test code and also data quality in depth. Data quality is the missing ingredient in almost all programmers. In part time, I'm a special Software Quality Management Engineer known for wide spread knowledge of software QA ensuring REAL software quality from the conception through well established sales activities and finally good delivery for almost any software product or service. Part of this is being a Software Application Security expert. (Software Quality Management Engineer is a top management post. It is called engineer because it uses wide range of exact technologies.) Your satisfaction is guaranteed anytime I undertake a job small or large! I don't want to into more details, because it may seem very complicated and hard to understand. However, one of my major policies is that I need to make software use as simple as possible for users. And as convenient as possible. Within reasonable usage of development time and resources. Correctly working systems is the most major policy. It is extremely hard to attain. (Not even big companies can do this! None of them! Check out their user forums!) And sorry, don't compare my efficiency, speed, skill and correctness of work to others with less than 20 years experience ! It can't be compared ! Because I have much wider experience and knowledge base. Just to give you a proper performance comparison. I've been work my on Office like product which has approximately 5 times usage value and functionality of any Microsoft Office including Word, Excel, Access and OneNote. But I only use 1/1000 or less of resources MS had used and I'll have a 5 times better product in functionality and convenience. So, this is my efficiency. Even if it doesn't apply fully to scraping projects, I can do 3-10 times better scraping than any practiced individual. (It can be even 200 times better in rare cases.)

    minimalist graphic designer | simply by design

    United States - Last active: 2 days ago - Portfolio: 42

    Hello! My name is Sharon and I have a Bachelor's degree in graphic design from Oregon State University, and over twelve years of experience working as a graphic designer, both in-house and freelance. I prefer minimalist designs which are simple, memorable, and won't look dated five years from now. I specialize in designing logos and other print design which clearly identifies your company or organization in an impactful way. I design logos that are versatile and easily reproducible in a variety of print and online formats. I listen to your input and direction, communicate often and respond quickly, and welcome all feedback. I will continue to make revisions until you are completely satisfied with your logo or print design. “I strive for two things in design: simplicity and clarity. Great design is born of those two things.” -- Lindon Leader

    Software Engineer

    United States - Last active: 11 days ago - Tests: 8 - Portfolio: 5

    When you're considering who to hire for your next project, ask yourself whether you would rather hire a team of people who don't speak English very well and consistently provide terrible work at $10/hour for 400 hours , or hire someone with great communication skills and provable ability at $67/hour for 40 hours. My Experience I have over ten years of programming experience. However, I've learned that years with a language doesn't matter when it comes to programming skill. Critical thinking matters. If you absolutely have to know, I have experience in Java, C#, PHP, JavaScript, jQuery, ReactJS, HTML5, CSS3, SQL, Perl, Clojure, C++, C, Ruby, and FORTRAN. I've used a vast number of technologies including MySQL, DynamoDB, MSSQL, Oracle, PostgreSQL, EC2, SQS, C# MVC/Web API, Twilio. I've worked on projects ranging from hundreds of lines of code to hundreds of millions of lines of code. I also have extensive experience with OOP, the entire software life cycle (analysis, design, coding, testing, maintenance), performance tuning, and high-level system architecture. I've been the only developer on many projects, and I've also worked on large team projects where collaboration was necessary. Why You Should Hire Me I blow all of your other candidates out of the water. I have found that I am at least 3 times a better programmer than anyone I meet. This is not speculation, but simply based on the time it takes me to do the same project as someone else. Note: I currently work full-time as a software engineer. This significantly limits the projects I can work on and the time I have to work on them. If you foresee your project requiring full-time dedication or you are on a tight schedule, I encourage you to find another developer.
