Hardware/Firmware/Software Engineer

Portugal - Last active: 22 hours 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.

Craft Beer Blogger

United States - Last active: 1 month ago

Hey! I'm a beer snob. Well, not a snob, but a beer knows-what-he's-talking about (who wants to be a snob?). I think they call it a Zythologist- someone who studies beer. I think that's fair to say; beer is a passion of mine, and I know a great deal about it. Brewing it, tasting it, writing about it... The blog - benlikesbeer.blogspot.com - is really where I developed my beer legacy. I write a few times a month about "beerducation," seeking to educate people about the culture of beer, and how to appreciate it more. I am currently a Senior Marketing specialist, and maintain Ben Likes Beer on the side. I recently passed 40 posts and over 17,000 views (and counting). What's more, I have interest in combining this passion with my degree - a BA in Digital Media - meaning App Developments, 3D media, and games (if you get creative). Well, that's about it from me. I genuinely appreciate the interest, and I hope to hear from you soon.

Software Architect

Brazil - Last active: 2 months ago

I'm a Software Architect of the biggest credit union bank of Brazil. I work and define solutions from the desktop application (view) to the database. Worked before in other big bank (government) and developed and defined solutions for credit loans and lottery. For me, you do not have to know technologies. Instead, know how to solve problems. You can make the same solutions in several technologies. But you can make the solution only knowing the technology? In my career, I always completed what was asked me. And trying hard to make with high quality.
