After Poliedro Ingeniero's decision to cease its activity, and again with the aim of continuing with the projects started years before at Intecsa Internacional that were transferred to Poliedro Ingenieros, I created my own software development company, in which I continued developing in person and without interruption, in addition to directing it and making it evolve both from the technical aspect and from the managerial point of view, search for clients, selection and management of personnel, etc. without detaching myself from software development.

With more than fifteen developers under my charge, including permanent, temporary and freelance staff, at that time at Jaune Sistemas I developed, together with my development teams, a multitude of consulting and development projects, in addition to devising and implementing my own CRM product that was implemented in various clients and was an important source of income for the adaptation and evolutionary projects it triggered.

As a further service to some of its clients, Jaune Sistemas assumes the Systems Management of some clients, including Georg Fischer and Paisajes Españoles.

In order to cover some of the needs of Jaune Sistemas for which I was not trained, I received from the AB Group company a comprehensive training course in commercial tasks, from market segmentation, prospect search, selection of commercial objectives , deals, A, B, C, preparation and follow-up of first visits, cold calls, etc.
