• Shortly About Me

    I am an independent senior developer and chief digital officer.
    For fifteen years I have worked in design, development and management of high traffic websites and data intensive transactional applications for the most demanding customers and thriving startups.
    I am a rare combination of developer, manager and business consultant.

  • Java and Scala

    I have been continuously developing Java applications since 2001. I have mainly developed high traffic websites and transactional applications for big companies at the most demanding environments.
    Lately I am moving from Java towards Scala. I like Scala because it feels like Python whilst taking advantage of all the powerfull Java libraries available. I am also a great fan of Akka Actors model over java.util.concurrent.

  • Lead Development

    I practice thorough, innovative and effective software development.
    A lot of people care about technology. Many of them are in fact obsessed with technology.
    They have fun with it, or even think that they are smarter than others ones because they know some low level details that others ignore.
    I do my best to reach a balance between pointless technology adoption and sound innovation.
    I lead developers from the trench. Being the first of them.
    Caring, understanding, taking controlled risks.
    Mentoring, letting them grow and contribute.
    “Talent” is the magic word endlessly repeated by managers and recruiters,
    but if you do not truly make a team then you are going nowhere.

  • Agile Management

    Agile is good beginning, but just that, a beginning.
    Over the last ten years Agile has become a best practice, but a best practice is also a common practice.
    If you are just practicing Agile then you are making no difference with any other.

    I have worked with several methodologies over the years, from heavy ISO/IEC standards or Prince2 to eXtreme Programming.
    I have arrived to something called Dragoon Dreaming which is a kind of nearly bug free code that provide great user experiences.
    Agile is a set of methodologies that focus on delivering the maximum amount of code as soon as possible.
    I believe in delivering actual Return Of Invesment to the software maker and not just more lines of code.

    My biggest team was one that I had at ThyssenKrupp with over 40 developers for the updating of its ERP to .NET technology during 18 months.
    I have experience writing commercial proposals, scheduling projects, doing budgets, controlling execution, recuiting people, motivating high performance teams, gaining executive support at organizations and reducing the deployment friction of applications.

  • Chief Digital Officer

    I have co-founded a couple of successful start ups in 2003 and 2007.
    I have experience pitching to VCs, developing applications from scratch with few resources, recruiting people, motivating high performance teams, controlling execution, doing marketing and applying for credits and subsidies. I contribute a “digital vision” to the company, connecting business needs with technical solutions. Not only I add value in technology but I also know how to seek for business opportunities.
