Combining both experience and knowledge I can quickly identify and assess customer/client needs and find solutions to suit their requirements.

    Consulting Analyst - Application Architect - Project Manager PHP,JS

    Romania - Last active: 2 days ago - Tests: 5 - Portfolio: 5

    I graduated in Computer Science at Polytechnic University of Bucharest, Romania. I also have a masters degree in Advanced Computer Architectures. In 2012 I started my PhD. I have been working as a freelancer for 7 years now but I also had some regular jobs in the past as a software developer at some well known companies but decided to quit so I can only focus on freelance projects. I have experience with most programming languages, from C, C#, Java, C++ to Python, PHP, SQL, Javascript, Haskel, Clips. In the recent years I've mostly programmed PHP, Javascript and custom web applications. Frameworks I've worked with: Zend Framework, CodeIgniter, Django, Drupal, Wordpress, jQuery, Bootstrap, and any other PHP popular framework. I have two partners I work with on all projects, Mihail - developer and Petru - artist. I also have a lot of finished projects, websites I can show on request. Work Policy: * I try to deliver the best quality possible, but this is often a trade-off between time, budget, and the specific project situation. (For example, not all clients would want the time/money investment in creating a full unit test suite). I usually suggest a LAMP stack using either PHP or Python. * I'll be honest. For example, I like giving suggestions on how to save time/money even if that means less billed hours for me. I only work on hourly projects. Thanks!

To be more precise I owned my own software development company, focusing on windows based client developing under C#, WPF, SQL Server, WCF and all the good stuff that comes with it. While my team (and I) have been focusing on this side I got myself involved for the recent 4~5 years in the area of Business Intelligence. I am on an expert level in terms of data warehousing and business intelligence solutions under Microsoft Technology. SQL Server, Analysis Services, OLAP, MDX, DAX, PowerView, PowerPivot and even Power BI and Sharepoint is something that I work with on a daily basis. I am also very engaged in software development. That is what I learned back than and that is what lets me build a "face" on top of all that data analytics. My recent project was about an enterprise business planning suite developed in C#, WPF, WCF. It has just recently been rolled out to around 150 users all over the globe.

    Poland - Last active: 4 days ago - Tests: 4

    With over 200 Google penalties removed WITH LATEST PENGUIN 3.1 PENALTY (and link audits done), I know what causes them. I'm working with all types of Google penalties: manual or algorithmic. Full portfolio is here (orange box): http://faktor.biz/ban-lub-filtr-od-google/ - or look at the bottom "other experiences" I'm working with: - Google manual penalty - Google unnatural incoming links penalty - Google unnatural outgoing links penalty - Google pure spam penalty - Google thin content penalty - Google poor quality content penalty - Google algorithmic penalty - Google penguin 2, 2.1, 3.0, 3.1 penalty - Google panda 1, 2, 3, 4 penalty I also have a Link Research Tools Associate Certificate. About hourly rate - price depends from number of linking domains. I prefer to work with fixed price, so I've adjusted my hourly rate to it. Almost all Google penalties takes 2-4hrs of my work. If we agreed for example to 2hrs and I need more of them, You won't pay for additional hours and I just turn off the clock. Services in detail: - Google manual penalty - given by real people from Google SQT/SQE team and has several variants - Google unnatural incoming links penalty - refers to unnatural, artificial links pointing to Your website; in 99.9% made by hired SEO company or by competiton (negative SEO) - Google unnatural outgoing links penalty - refers to unnatural links coming out of Your website; it could be link exchange system, affiliate program, etc. Also could be made by You/other contributors of Your website - Google pure spam penalty - refers to poor/aggresive content on Your website; it was made for search engines and not for users to boost search rankings positions - Google thin content penalty - refers to content which is very small or copied in a large amount of all content on Your website - Google poor quality content penalty - as above - Google algorithmic penalty - given automatically by search engine; for now has two well know options - Google penguin 3.1, 3.0, 2.1, 2.0 and older penalty - refers to poor quality of links pointing to Your website; spammy, toxic, black hat techniques were used - Google panda 1, 2, 3, 4 penalty - refers to poor quality of content on Your website; mostly copied from other sources or made for Adsense Other services: - Backlinks audit - I could do a link audit and select good and bad links; after selection You could request removals for each links or use disavow (Your choice but I've found disavow is enough and works). This is good to check and clean link profile to make seo job more effective. Also if traffic/serps suddenly dropped, it's possible You have a google penalty (at least algorithmic) - Keywords research - If You don't know what keywords are good, I'll help You - Competitiors keywords research - I could find which keywords are used by competitors - just send me the list of them and I'll find all (and select good places for earning links) - Ongoing backlink audit - monthly or weekly link profile check; good if You have ongoing negative seo
