With a bazillion years of professional experience within the IT and Software Development landscape, I've done lots of different things: mission critical customer support on high-end UNIX systems (yes including being "on duty" 24/7 for many many weeks!), huge datacenter consolidation and move projects, developed tailor made large-scale IP-based VoIP solutions, architected scalable data processing and visualization pipelines, created Promptar a CTI software product, lead IT services and project teams, trained development teams, customers, and partners around the world.
Nowadays I'm focusing a lot of my professional activity on software development and Python, and I'm pretty happy about it!
