I worked on a B2B uni
ed communications solution. There, I had to rewrite a module
of the core product in C++ responsible for notifying the availability (available / busy)
of the users inside a company using IP phones/so
phones. I independently created
a tool to stress test this module with very high load which gave us important
feedback at that time.

I worked on a company product o
ering telecom services to customers in Germany.
There I took responsibility for a new project whose purpose was to capture, store
and query all the call data from our servers. I participated in related open-source
projects. I implemented features which impacted 5 millions of users of our telecom
service. One of my most complex features was saving call data real time inside a
MySQL database, so I had to optimize the process in multiple ways (temporary
memory tables, optimizing indexes, MySQL events and triggers, sharding, storage
engine optimization).
Skills used: C, PHP, MySQL, Linux, Bash
