tech startup CTO - bootstrapping your business

France - Tests: 1 - Portfolio: 3

I've already held a CTO and lately CEO position in tech startups. With 5 year experience in IT development & startup bootstrapping, my core strength lies in a rare business execution + IT dev experience & competency. I have hands on experience in managing small agile dev teams and even programming (C, Java, Play, PHP, SOLR, AWS, SQL, noSQL, ...), bringing new IT products to life and maximizing the investment potential of the technology. Why would you hire me? I'm the perfect fit for the entrepreneur / CEO who requires trusted high-level technical consultancy (cloud services, big data, machine learning, search servers, distributed application, mobile servers, ...) and needs someone to manage the development team (or even hire and get them to work in no time). Business plans I personally wrote and detailed experience in managing dev teams available upon request.
