    I've had a passion for electronics since I was 14, and started as a hobbyist well before obtaining my degree with the utmost distinctions. Offered a position at a R&D institute, I ended my year of internship as a digital systems designer. Afterwards I pursued a career in safety electronics, specifically lifts. To broaden my horizons I started my own company, which I've managed since 2009, where I've developed electronics for motor control, telecommunications, explosives control, pharmaceutical and medical grade airlocks, IoT, radio controls and much more. I have plenty of expertise in electronics and PCB design, safety electronics, cryogenic electronic systems, EMC, design in high noise environments, hardened systems and all sorts of electronic devices in hostile environments.

    I've been working on this for +13 years, from desktop development (C++, QT, .NET) to mobile development (Cordova, Ionic), game development (Unity, Gamemaker) and for the last years, more focused on web development. Almost all my web projects are made in PHP, MySQL and HTML, CSS and Javascript (mostly jQuery) but I have a little experience with Angular and TypeScript too. I used Codeigniter and some CakePHP and Symfony, long time ago. Also, I have some experience with Wordpress, Prestashop, Python, Arduino, Google Cloud... My role was usually a full stack developer. I did frontend and backend, HTML, CSS, Javascript, PHP programming and database creation. I installed and configured a couple of Linux servers too and took some first steps with Python.

    ABOUT ME I'm a full time freelance software developer and consultant, highly experienced in designing, developing and managing web, mobile and desktop applications of all sizes. I've been developing software commercially since 1998, and a hobby programmer since my childhood. I currently own and operate Brava Software Solutions, a software consulting and development agency currently based in Alicante, Spain. Previous clients and work experience include Quill Meetings, DHL, Securicor Omega Express, Capscan, Monsternett AS, The Restaurant Zone LLC, Sunfly, Dooster, Claims4Free and more. I'm a native English speaker, originally from London. WHY SHOULD YOU HIRE ME? Let's be honest .. you've probably seen my bid and thought, "Wow, that's a little higher than some of the others, what makes this guy worth it?" Well .. hire me and I'm sure you'll very quickly see why. Not only do you get a highly motivated and passionate software developer with decades of experience focused on your project, depending on your needs, you can also access to the highly talented team of engineers and dedicated project manager that my agency can provide. No middle men or answering services, you get to talk directly to the people working on your code. I also strive to offer a flexibility towards my clients needs that is hard to find in this industry and will happily adapt working hours to suit your needs, whether you need just a few hours every now and then, or a huge dedicated burst to meet a deadline, you'll find you can count on me to deliver. Not only do I pride myself on producing clean, robust test-driven and fully linted code, but because it's second nature to me I can also do this fast and efficiently. I'm confident that you'll not only receive outstanding results, but as my many repeat clients will agree, you'll end up getting far more value than the cheaper competitors. I'm also very picky about the projects I choose to bid on, only pursuing ones that I feel will be truly engaging over the long term. By approaching work this way, you'll find that I throw myself into my work like nobody else. You'll find that you'll get not just a developer, but an individual who's genuinely passionate about what he does and someone you can rely on to handle every technical aspect of your project from start to finish and beyond if needed.
