Training
My experience as trainer:
- I’ve taught in more than 250 courses since 2002, including onsite and online training for companies and courses for public institutions;
- from 2009 to 2017 I was a trainer and a study book author for the webmaster curriculum by Webmasters Akademie Nürnberg in Germany (WE);
- from 2002 to 2011 I taught as a freelancer at the faculty of computer science of the university of Bolzano - first as a teaching assistant and later as lecturer.
Please contact me for training courses about the following topics! My courses are well-known for their high practical application because I teach only the technologies that I use in production in my work as a developer and system administrator/DBA.
Relational database systems
- Relational database concepts and SQL using PostgreSQL, MS SQL Server or Oracle DB
- Focus on PostgreSQL:
- administration (DBA), including setups with replication and connection pooling
- client programming (e.g. libpq, JDBC, psycopg) and server programming (e.g. PL/PgSQL)
My certification: 1
