    Microsoft Access / SQL Server Developer

    United States - Last active: 3 days ago - Tests: 1

    I first began developing an Access database for a small company in Florida. I became a permanent, part-time employee in 1998. As the database project grew we expanded the back end to a SQL Server database. Over the years I've studied both Access VBA and T-SQL and have become very good at designing network based applications based on this popular combination of Microsoft products.

    Hardware/Firmware/Software Engineer

    Portugal - Last active: 10 days ago

    I am a 40-year old electrical engineer with a passion for sophistication and innovation. I have a lot of experience in many areas, a result of both my professional career as well as my own personal projects. Detailed profile information can be found at http://profile.rilhas.com I can design, test, and manufacture hardware (including PCBs) using microcontrollers, FPGAs, USB, UART, I2C, and many more, and integrate them with computers, embedded systems, mains power, motors, various sensors, etc.. It is not uncommon for hardware projects in which I’m involved to incorporate both firmware and software, or even connect to the internet or with mobile phones. I have a lot of experience in the PC world, both as a user and as a developer. I have developed high density ISDN telephony application servers (IVRs) for the main Portuguese telecom operator, with an installed base of over 2000 channels, including a voice mail system complete with voice and text fault-proof database. I have developed a large number of computer systems, both servers and clients. My work with IVR's later included testing and using various ASR and TTS technologies (for automatic speech recognition and automatic speech synthesis from the major providers like Loquendo, Nuance, Philips), applied to various areas from the IVR system themselves (directory assistance, flight booking, and more), a help support system for the elderly (consisting of an emergency telephone help server for the national Red Cross), all the way to systems for the hearing impaired (integrating with JAWS screen reader, for example). I have worked with a team to develop a tool for airport management systems, where my contribution was the development of a complete graphics subsystem based on OpenGL, which is being used up to this date (more than 10 years later), due to its capabilities not having yet been surpassed by the competition. I've developed technology to analyze video images and detect a large number of situations, including FOD at an airport in Açores, intrusion detection, early fire warning systems (marketed as CICLOPE), fire prevention systems at PORTUCEL (one of the main producer of paper and other products), illegal car parking, subterranean bus parking, automatic lane management (and infraction detection) on the 25 de Abril Bridge, and many more. I also developed technology to monitor and track bird movements using radar data. A first version used the radar image, and a more recent version uses the raw radar data (captured using a high speed data acquisition system that I also developed specifically for the radars being used). Since this system requires the display of large amounts of data (images with 30+ MPix) I also developed the visualization component (based on OpenGL). I also have some experience in CAD modeling (owing mainly to the fact that I've owned a 3D printer for several years), with which I have created numerous models for small production runs of plastic objects, mainly to assist with electronics projects but which I have also used successfully to create inexpensive plastic connectors and other components for a company that manufactures and installs solar pool heating systems, including automated 2" valves. I’ve also created custom shaped plastic cookie cutters for my wife and toys for my son. :-) I've produced several promotional 3D videos for a few companies, and I also recorded and produced music albums for a number of artists. The systems I have developed in the past make use of (of have integrated with) a wide range of languages, systems, and technologies, including C, C++, C#, JAVA, J2ME, Android, Javascript, Ruby, PIC 10/12/16/24 assembly, i386 assembly, MMX/SSE2, Verilog, TCP/IP, UDP, OpenGL, USB, WiFi, Bluetooth, Raspberry Pi, BeagleBone Black, Windows, Linux, POTS, ISDN, ASR, TTS, among many others. Many of the projects I've worked on have included other people, and I have been the project manager on most of them. For the larger projects where I was not the project manager (like those involving airport security, for example) I was the team leader of the corresponding project component. Given my extensive experience with complex and innovative projects (where a solution is not always obvious from the start and a great deal of creativity is need as the project progresses), I have also developed good skills and intuition for preventing and detecting bugs, both at a code testing stage as well as (more importantly) at a design or specification stage. These skills have proven crucial over the years, and I think that the success of all the projects I worked on depended heavily on them.

    PHP,HTML,CSS,Java,JavaScript,Perl, Web Developer, MySQL, Linux: 10+yrs

    United States - Last active: 3 days ago - Tests: 6

    I have over 14 years of experience building, fixing and maintaining web applications and their back-ends (large and small). Web programming is my bread and butter- HTML/CSS and whatever drives it on a LAMP or LAMJ stack (PHP, Java/JSP, JavaScript, Perl, etc.). Plus I can administer the technology needed behind the scenes for database setup (MySQL and postgreSQL), maintenance, cron jobs, and systems administration (RedHat/Fedora/Centos or other Linux, etc.) Whether you have just a quick need for someone who knows their stuff, or a larger or ongoing project that might require recurring tasks, I'm here to help. I'm not a Jack of ALL trades, but I also am pretty savvy when it comes to website UI design, SEO and internet marketing, including email and social media.

    SEO/SEM/Web/E-commerce Consult/Implement

    United States - Last active: 3 days ago - Tests: 2

    It's simple: When someone searches online for your product or service, you no longer get lost in the million responses, you come up on page 1. I make your webpage work like it was always supposed to. Prepare to expand. Google uses several metrics which are time consuming to learn as well as heavily guarded secrets to rank your site that require an expert to navigate. To try it on your own is to realize you require someone who knows what they are doing and can devote hours to your online marketing success, and with guaranteed - not speculative- results. A good SEO/SEM specialist pays for themselves in a very short time period. I also have a full team and run RankChallenger.com. We design and make websites that are SEO ready, and continue to provide zesty citation, backlink, and content relevancy to ensure very high rankings in search engines both locally and nationally if desired.
