C++ expert, and a few other things

Programmer, Entrepreneur, in the house since the 1990's.
REAL expertises : C++ (and somehow C), multithreading (and especially debugging those things), networking (and especially when it has to be fast and reliable), cryptography (implementations, even post-quantic, reasonable knowledge about the mathematics behind), SQL, very up-to-date in my knowledges (a work by itself), cryptocurrencies, and especially cryptonote-based ones (Monero is cryptonote-based, as are AEON or Sumokoin), forking and tweaking.
Reasonable capabilities : Java, Python, .NET, Web in general, NoSQL, GIS (PostGIS, MapServer, GDAL, Proj), everything sysadmin-related on Unices and Windows.

And many other things.

Admitted weak points: everything Apple, everything big IBM systems (Z/OS, MVS).

I intend to be an absolute professional. Which means absolute courtesy, and clarity with my clients, _documented_ work, and real best effort for everything else.

My activity is today 100% freelance, but not 100% Bitcoin. I hope and try to do more Bitcoin. Feel free to question me about anything.

Oh and... There are no French persons in the top freelancers. I am here to change this!

PS: I changed my account, because of an email problem. Those who know me will recognize me, I am the same person.
