Start to prog at 2006 on Delphi. After 2 years was 8 years on C++ writing server-side of online games (also I use Lua to use it from C++ code for fast logic changing without rebuilding and even restarting server). Databases were: PostgreSQL, Oracle, MySQL (MariaDB nowadays). And then I saw Java. And I like it :) Now I use Java, Gosu for writing web-services. And start learning GOlang to write big great systems with Microservices paradigm 'cos I think it's the future. When I will became more experience in GO I start to use gomobile for very fast Android (and maybe iOS) clients for any Big Great System :)
