QualeaJune 2009 - September 2010

- I've been part of Qualea for 14 months. First as an intern, then as a part-time job in parallel with my studies.
- Internships first focused on the setting and deployment of a TOIP infrastructure (Asterisk) for a small business (10 lines).

- Then, as internship was not over, I started working on tools to help DBA in their jobs. DB optimization was the main activity of the company, which is mainly providing consulting on Oracle DBMS optimization. As it was promising I carried it on as a part-time job. The tooling was split in 2 software:
- Smart eavesdropper
- Reverse engineering and data analysis to understand network protocol format (Integer encoding, flags meaning... ) It lead to an almost complete understanding of the protocol.
- Main goal was to follow network activity to optimize database configuration but it went as far as enabling network injection taking over the TCP connection, revealing security issues.
- Queries decoder
- Semantic analysis of SQL request for automated optimization:
- From cardinalities, most common column requested... It makes it possible to determine which index should be created on a table.
