I'm offering
I have a proven track record of 10 years handling complex software architecture and development.
I have accumulated prime experience through relevant industries, such as a contractor offering specialist skills on the design and implementation of mission critical systems for consultancies and governments departments. Previously I have worked as part of a High Performance Computing team in the largest South American Research Laboratory; in the Public Administration sector by providing Business Intelligence solutions; in the media sector, by empowering Impresa, the largest Portuguese media group, upgrading their main editorial platform; in the touristic and ground transport sector by transforming BookingGo-Rides ground transport solution; All these experience gathered led me to start my own contractor career, where I am able to quickly provide all my software development and architecture expertise to relevant teams and projects such as the Department of Work and Pensions in the UK government.
