    I am a C/C++ & Unix specialist with devotion toward elegance, low latency, high throughput and performance. The broad range of computer fields I have worked on made me a clear thinker as system and program architect. I invite you to contact me so I am enabled to send my resume and you get a better idea of who are you potentially hiring. In the mean time you can find some detail at https://www.freelancer.com/u/waws.html. I feel very comfortable in Unix alike platforms (Linux, Solaris, Aix) but I can do a similar job on Windows when related to internals or performance sensitive applications. Some activities that I enjoy the most are kernel and device driver programming, performance tuning, compiler construction, data communication and protocol implementation. Even though performance and low level programming pay my everyday bills, I am avid to improve in others disciplines like big data, NoSQL, MapReduce, cloud and parallel computing. I would be more than pleased if you offer me that kind of opportunity. A strained list of my skills follows. • C, C++, C++11, Java, X86-64 SPARC and ARM Assembly. • Unix and Windows Internals, IPC, concurrent programming. • Shell scripting, AWK, Perl, Python. • Windows Scripting Host, JScript, VBScript, VBA. • Pipelining, Unix domain sockets. • COM, OLE, DDE. • Corba, BUS architecture, Tuxedo. • Oracle (PL), MySQL, Postgres. • Linux modules and Windows device driver programming. • Profiling, tuning and debugging. DTrace, Valgrind, IDA, gdb, gprof, strace, truss. • Linux modules and Windows device driver programming. • Reverse engineering, DLL injection in Unix and Windows. On the personal side, I am persistent in almost everything I do. I have good sense of loyalty and always committed to the project. I like to train endurance running and, I would like to have more time, to play the blues on acoustic guitar.  less
