Hardware/Firmware/Software Engineer

Portugal - Last active: 1 day 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.

Software engineer

Sweden - Last active: 06/06/2013

Summary Ever since I can remember technology has been an important part of my life, this has taken me from founding my own small technology company back in Sweden to working on projects all over the world. This same focus on technology also allows me to have a broad understanding of how technology is evolving and it has given me the ability to widen my knowledge which is now spread across several different kinds of technological areas. References will be provided upon request. Specialities I am an experienced developer within the mobile sphere having built both back office software as well as fully fledged content delivery and billing solutions for some of the biggest carriers in the world. Ive had several titles in top lists in the apple appstore and on carriers across the world. While mobile has been my main focus the last couple of years my base lies in web where I have developed solutions to allow companies of all sizes to have a presence on the web. I’ve built systems and websites for everything from small local companies to big global companies. For the last couple of years my focus on web has been towards Ruby on rails using a BDD philosophy having finished both big and small sized projects by successfully leveraging cucumber acceptance tests and story writing as well as unit tests based around rspec. While being a partner in different businesses I have also gathered skills in business planning and management.

Canada - Last active: 20 days ago - Tests: 4

Hey! I'm Charles! I have three major passions: Programming, Writing, and Biology. I am currently working on getting my degree in Computing Science. I have worked for multiple startups in the web/mobile app programming space. My expertise is specifically Python, C/C++, SQL, Haxe, and a bit of COBOL (Hey, Learned it to better understand how good we have it now). I've built everything from automation scripts, web-scraping tools, analytics tools, statistical analysis tools, engine management systems, text spinners, translation tools, and even biological models. I am also a published author, with a personal blog that gets well over 1000 hits/day, and a variety of Self-published Kindle books that have sold well. I am looking for some part-time work to help pay the bills, and keep me living the life that I want. I don't like being chained down in one place, and I love travel. I am competent in both programming, as well as techincal/generic writing, and I do offer text spinning services as well.
