WordPress + Loading Speed + SSL + Optimization

United States - Last active: 22 hours ago - Tests: 6

Skype: littlebizzy My specialty is loading speed and on-site optimization re: WordPress websites. Specifically, I can optimize your DNS records, web server (VPS), WordPress (cache, plugins, etc) and source code (HTML, CSS, JS, fonts, images, etc) to be more efficient and secure. I am well versed in WordPress (#1 on oDesk), WooCommerce, Nginx servers, CloudFlare, SSL certificates, and SEO. Loading speed and SSL are now two of the biggest factors in SEO according to Google, whose robots are constantly analyzing the quality of your website. Don't get left behind by the competition. https://www.littlebizzy.com/seo-is-dead Whether you need a one-time consultation, or fully managed WordPress hosting, I am not shy in making important suggestions that will improve the experience of your customers. I can work alone as a project manager of sorts or alongside your current team members. I stay in close touch with your team via email, Google Docs, and Skype. My recommended services: CloudFlare (DNS) - http://goo.gl/CMyxyZ Digital Ocean (VPS) - http://goo.gl/kY6AWB MaxCDN (CDN) - http://goo.gl/qawqv6 CodeGuard (backups) - http://goo.gl/FNF2j5 DigiCert (SSL) - http://goo.gl/bW5KJf YMLP (newsletters) - http://goo.gl/YqUFHi For email, I recommend Google Apps (name@company.com) + SendGrid (for things like lost password reminders, WooCommerce notifications, etc).

Graphic / Web Designer

Indonesia - Last active: 22 hours ago - Tests: 4 - Portfolio: 29

I am a Graphic Designer based in Surabaya, Indonesia, specializing in User Interface Design and Development. I build clean, appealing, and functional interfaces which comply with the latest web standards. But that's just a part of it. Design is my life. It's something I do before I go to bed, and something I can't wait to do in the mornings. Without it, my world would be black and white. I design with Photoshop, Illustrator, Dreamweaver, and Flash. I code sites with XHTML and CSS, using a little of JavaScript, Actionscript, and PHP.

Argentina - Last active: 22 hours ago - Tests: 17 - Portfolio: 2

TOP RATED!! Since 1985 designing and coaching companies of all sizes and industries. My passion and dedication have been rewarded with 26 international awards, Including New York and London Festivals. From everlasting logo design to the most complex UX mock ups and UI crafting, I am as enthusiastic as the first day. I am detail oriented (very picky) and deadline driven. I add value to my work by providing new insights, vision and ideas. I see the big picture even when clients assign me a very specific detail of a work. I am a natural out-of-the-box thinker and creative problem solver. Before applying a traditional method I push the boundaries to let the innovation gain terrain. HIRE ME NOW! You will never let me go! Do it before I become more expensive!

Canada - Last active: 2 days ago - Tests: 7 - Portfolio: 6

25+ years of programming, 14+ years as a job. It's not just how I make a living, it's also something I really love and enjoy doing. I develop robust desktop software, great responsive websites, optimize databases and create reports. I communicate well and feel that it is my duty to let the client know how things are progressing. I also give constructive input but respect the client's final decisions. I program desktop programs in C# and VB.Net (both WinForms and WPF) and websites as either ASP.Net, MVC 5 or single page Angular applications. I have worked heavily with MS Access and MS SQL. I have extensive experience writing reports for SQL Server Reporting Services(SSRS) and RDLC reports for web and desktop applications. Here are a few aspects of the challenging projects I have worked on so far. Added eyedropper functionality (pick a color from an image) using HTML5 Canvas and listed fonts installed on the computer to a single page SVG graphic editing web app. Created custom mouse cursor. Runs on Chrome, Firefox, Safari, Opera and Internet Explorer. Created response Bootstrap WebAPI/Angular site to teach Latin. Created an MVC 5 demo website for travel agents to create and manage quotes. Wrote a program to play music on a low-latency and high fidelity 8 output channel professional sound card. Created an output program for industrial displays. Wrote a program that receives industrial protocol messages over TCP/IP and follows with the appropriate action. Read and nicely write INI files. Created solid user registration and product activation for desktop applications. Created graphic editor with easy user interface for complex set of symbols. Advanced document layout for specialized graphics. From a third party website, retrieve the distance between two locations for use in calculations. Load GoogleMaps map in desktop application with route between source and destination addresses. Created an ASP website to edit database. Created custom JqueryUI controls to validate and display the data in a user friendly way. Make websites with HTML5, javascript, and JQuery. Created and optimized MS SQL databases. Displayed time from events in database in the user's time zone. Optimized, rotated and created arrays of 3D data. Created fast working implementation of a query to find areas of similar data throughout millions of records for MS SQL. Made reports (SSRS) with automatic emailing to the clients. Made a RDLC report for a desktop application based on MS SQL. Implemented a full costing program in MSAccess. I also speak, read and write English, French and Spanish fluently.

Russia - Last active: 1 day ago - Tests: 9 - Portfolio: 27

Currently I am focused in creating rich client-side apps using JavaScript advanced techniques, CSS3 and HTML5 features. I am keen in creating perfectly looking user interfaces and visualizations with help of D3,js and my great experience with UI/UX. Using best practices and a streamlined workflow I manage to work on complex solutions that include hundreds of user-cases and apps views that are often created as real-time dynamic apps. I use TDD where applicable in my frontend engineering work. Being a problem solver for my clients I am sure that clean, semantic markup and content-driven, responsive layouts are the way forward. I believe in building sites that are device-agnostic, adapting layouts and experiences to a user's viewing environment. I am a fan of progressive enhancement in my work. Having solid backend development experience with multiple languages like Python, C# and JavaScript I try to imagine and see the whole picture of projects I work on.
