Several years of experience evolving into a proficient programmer and a think-ahead architect. Has been involved in cutting edge IT projects and successfully competing against big names like IBM, Computer Associates and Unisys. Some of those projects include: Transaction Monitor design and construction Compiler design and construction Transparent TCP/IP sockets over SNA transport networks Multitasked preemptive kernel for the x86 architecture Multiplexing of several undisturbed processes over a single TTY SCADA scheduler design and construction The result of these challenging work was several times awarded with a job offering from the competition. It has been combined and in association with more mundane activities like: Web programming, admin and internals Database programming, admin and internals Platform PCI certification Hardening and security at the programming and admin level Administration of Unix alike platforms Switch programming at a PSTN IVR/ACD/CTI programming Some MS Windows admin and internals programming Microcontroller programming Coaching and mentoring Being educated in the old school were performance was prime, and being trained by the tough competition against big brands, I had to make the transition by myself to technologies starting from OOP to IT approaches, which now are commonplace, like: RUP, Design Patterns and Agile Software Development. Apart from the expertise mentioned above the specific hands-on experience and skills I offer as a freelancer includes, but are not limited, to: C/C++ Java Perl Oracle admin and PL/SQL programming PostgreSQL admin and internals Apache Tuning/Admin/Internals Tomcat-Axis Tuning/Admin/Internals SSL/TLS server and client programming TCP/IP sync and async programming Multithreading and asynchronous programming Multiprogramming Unix scripting Unix/Windows internals Solaris Kernel internals They are complemented with creativity and commitment with quality, timely delivery and convenient prices.
