Miguel Duarte’s Summary

Project Manager, Test Planning and Execution, Application Architect and Developer, Team Management

In 2008, I became responsible for Mediation Architecture and Development team. The key challenge is to support the development of new products and services, bridging the business requirements with the TMN mobile network infrastructure. Apart from project and team management, I also have an active role in the more technical aspects of Software Engineering, which I believe are key to support the ever changing world of mobile operators.

In 2005 I've joined the TMN Mediation Team, splitting my duties between software engineering and project management.

Spreading and gathering knowledge is also a goal. I have an active role in several technology groups/events:
- PT-Jug: Portuguese Java users group: I've authored two technical sessions on "Scripting in Java Virtual Machine" and "Distributed Version Control Systems"
- Lisbon::PM - Lisbon Perl Mongers: I've presented several talks
"When not to use Perl","Inline::C","Perl Multi threading","Perl Debugging"
- SAPO Codebits'08 - Delivered a session on "High Performance Development With Java - Available online http://www.slideshare.net/malduarte/codebits20082

I believe that we've only seen a glimpse of what good and innovative software engineering can to do make the World a better place, and I hope to have an active role on that.
