Work experience

06/2010 — present

Oracle — Principal Software Developer, BI & EPM Development.

C/C++ application level protocols (compatibility, scalability and performance) over TCP/IPv4.
J2EE programing in Eclipse IDE for Weblogic 11g and Tomcat 6. Web services. Dependancies, deployment and packaging.
Porting to Windows x86/x64, UNIX (AIX 5L, Solaris SPARC/x86, HP-UX 11i PA-RISC), Linux (x86/x64).

03/2000 — 05/2010 (until LEC with Oracle after aquisition)

HyperRoll — software engineer and system integrator.
Daily tasks include:

Package builds (i.e. releases) generation and primary automated testing before passing builds to testing team.
Keeping the portability and source code porting to all supported platforms (AIX, Solaris, HP-UX, Windows on x86/x64/IA64, Linux, Tru64) using common conformance standards relevant to a specific OS (POSIX.1, POSIX.2, XPG4, etc) and appropriate data mode (32-bit and 64-bit).
Source code reviews.
OS level and infrastructures related source code development and bug fixing.
Maintenance of development and testing environment.
Supporting developers with build, profiling, coverage and automated validation processes and with OS related problems.
Supporting Professional Services and Support teams with urgent customers' issues.
Supporting old and obsolete product versions.
Oracle Express Server (OES) connectivity maintenance.
Core (post-mortem crash dump) files' analysis, including source code vs disassembling analysis for x86/x64, SPARC, PA-RISC, Power, Alpha processors.

General tasks (not on daily operation):

Creation of automated internal development and testing tools (leak detection library, automated regression testing suite).
UNIX applications installation and customization of products that include IBM DB2 UDB 7.2 and 8.1, IBM DB2 OLAP Server 7.x and 8.x, Oracle RDBMS 8i, 9i and 10g, Oracle Express Server 6.x.
UNIX system configuration as for internal usage by development, testing and support teams, and for customers' systems.
Regular UNIX system administration related to OS and development tools updating and patching.
New OSes installations and configuration for specific team purposes.

Researches with lower activity:

Build process time decreasing (dead code and modules elimination, #include files dependancy minimization).
Research on build-time (e.g. compilers) optimizations for application run-time.
Research on run-time libraries optimization. Custom run-time functions rewrite (e.g. mem* and str* family) opportunities.
