I am one of the top database design specialists on oDesk. My sophisticated hand-crafted database design will save your organization significant time and money. I am a serious professional with over 20 years of experience as a programmer and database specialist. My emphasis has been on creating elegant SQL database design integrated with user-friendly front-end software (desktop and web applications). I have worked mainly as a database designer, programmer and database administrator for bioinformatics, biochemistry, molecular biology, and biomedical research applications. I also have extensive experience programming database-centric software (websites, web applications, desktop applications) for publishing, business, financial, personnel and other purposes. One of the things I enjoy most is creating database schemas which make sense for both programmers and non-programmers, designing with an eye toward flawless data integrity, maximum maintainability and optimal performance. I love crafting websites and web applications which perform with shocking speed. It makes for a better experience for users, developers and administrators. My expertly designed database systems - with well-written queries, intelligently chosen indices, and sensible caching strategies - can easily perform 10 to 100 times faster (using the same underlying hardware). My emphasis when working with clients is on their data and system usability, not specific trends or technologies. But in case you're wondering about some specifics, I strongly believe that the database data should be integrated with but also somewhat independent from a presentation/application layer. Data in the database should be easily accessible from one or many different applications built using one or multiple different technologies. Currently I favor PHP/JavaScript/HTML5 for web applications, RealBasic/Real Studio/Xojo for cross-platform applications [Mac OS X/Windows/Linux], Xcode for Mac OS X-only/iOS applications, Visual Studio for Windows desktop applications. I prefer using MySQL for back-end RDBMS, but I also use Oracle, Microsoft MS SQL Server, PostgreSQL and SQLite on a regular basis. If your data and information organization is already in great shape, and if you are satisfied with how your database-integrated software and website performs, then you probably don't need a high-end expert like me. I can make routine modifications, add to well-crafted existing systems, etc. But so can many other people. But if you're just getting started on a new system that you want done right, or if you suspect your database website programming strategy needs an overhaul, then I can get you on the right track in a short amount of time. * * * * * * * * Let me mention a few of the client-friendly policies and practices I apply with all my clients. I don't do these things to distinguish myself from other contractors. (I would hope they all do the same.) I do these simply because this is how I would want to be treated if I was the client: - I work for zero up-front payment; you can pay me when I'm done. - With fixed-rate contracts, if you don't love what I do for you, you don't need to pay for it. - You don't need to have your own web servers; I can host development and/or live production work on my own high-capacity servers. - I don't mind working on a client's servers, or doing dev work on my servers and transfering finished work to client's servers. - I do not charge clients for hosting their websites or software systems, or for moving their websites or software systems elsewhere. - I provide clients with root log-in access to all the work I do for them; you are welcome to log into the server (cPanel, FTP, and phpMyAdmin) at any time and copy or back-up or move any work I do for you. - If I am working for you, all work product, all source code, all database design belongs to you. Always. Period. - I am happy to work with you and/or other programmers you enlist to work on a project; I am happy to pass off development work. - I do not provide mysterious "black box" solutions. I am happy to have you look under the hood at everything I do. You don't need to know anything at all about the inner workings of a system. Or you're welcome to ask about the most intricate details. - If we're developing a system from scratch, I prefer to do so using very widely-available technologies (PHP/MySQL/JavaScript/HTML5) which you can hire countless other people to work on if you decide to have other developers work on your system. - Do not be embarrassed to ask ANY question! I enjoy working with clients who have zero technical know-how in programming/databases/etc., partially because I appreciate their expertise in OTHER fields (real estate, art, medicine, law, science, civics, etc.) If you already know everything about databases and programming you probably wouldn't need me, would you?

Contact information at www.michaelriveraco.com (portfolio returning eventually soon). I'm not passionate about programming. I'm passionate about power and beauty.

I have a Computer Science degree. I work hourly. I don't give estimates or set deadlines. Leaving me a voicemail by phone is the best way to get my attention (as soon as I put my contact info back).

I know how to develop software with good quality in short time. The best project lifecycle under my development is: 1) Fast prototyping from UX scenarios and wire-frames. 2) Implementing functional and unit-tests for front-end and back-end. 3) Development phase with continuous integration and fast iterations. 4) Production. I specialized on web sites and web applications with complex structure and back end. Also I'm familiar with usability and like to develop clean and light user interfaces. For web development I usualy use PHP or Python + Ajax (jQuery). This's the simplest and fastest solution for most web applications. I've big experience in development of very different applications from small innovative web 2.0 services to complex client/server applications (like SirsiDynix Horizon - an application for library workflow management). My another expertise is Java, I use it since 2000 for numerous projects. I always pay the most attention to customer needs. And I can study faster when need to work with framework/technology I never worked before. Please, visit my portfolio website for more information about me: http://stasdavydov.com/ Thanks!

Vitaliy is one of the most talented developers we have. His expertise are .NET related technologies and JavaScript but this doesn't mean that he is not able to be the best in other areas. He likes to improve his own skills working on different projects and learn something new.It doesn't matter if it's a new technology or an API, you can be sure that he adapts to any new stuff very quickly and deliver his tasks in time. He is also a perfect team player, maybe because he likes team sports :)

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.
