Linux system administrator (part time)
Emnico Technologies Ltd./Emnico Services Ltd.
- Support and continuous development of an optical network management (SONET/SDH) system in a Unix environment (mostly C++ on HP-UX and Linux).
key technologies used: CMISE - Native Win32 application development.
key technologies used: C++, MFC/ATL, WTL, Win32
Alcatel-Lucent (formerly Lucent Technologies)
- Worked in a global development team on telecom network management software for optical networks (SONET/SDH) in a Unix environment (mostly C++ on HP-UX and Linux).
key technologies used: CMISE - Low-level architectural work: porting of the low-level networking code from HP-UX to Linux; developed a debugging memory management library to facilitate detecting and tracking down of memory management bugs.
key technologies used: low-level networking API on Linux (packet sockets), accessing a program's call stack, reading ELF/SOM symbol table - Implemented new features according to requirements, tracking down and fixing bugs and crashes. Used programming language and external protocols depending on subsystem.
key technologies used: C++, Java, SNMP, CMIP - Developed a scriptable test-client in Java/JavaScript.
key technologies used: Java, Rhino, XML
SBS Software Ges.m.b.H.
- Developed several Java/JNI libraries to access Win32 specific APIs: i.a. CEN XFS, shared access to the same RS-232 port by multiple processes.
key technologies used: Java + JNI, C++, script-based automated code generation, multi-threading, Win32 - Worked on a J2EE application for monitoring self-service banking terminals: SNMP integration, database maintenance scripts.
key technologies used: Java + J2EE, WebSphere, SNMP, DB2 SQL - Prototyped a custom firmware for the Linksys WRT54G to build a cost-efficient, custom security appliance (firewall and VPN).
key technologies used: Linux, gcc cross compiler, VPN - Developed a replacement for the standard Windows shell (explorer) for self-service terminals that takes care of starting and monitoring application processes and prevents unauthorized access to the operating system desktop.
key technologies used: C++ using STL and Boost libraries; Win32 API for starting and monitoring processes; COM Automation for inter-process communication and JNI for the Java integration - Linux server and network administration: set up a centralised directory service, firewall and VPN (IPsec, OpenVPN) configuration.
key technologies used: Linux, LDAP, Samba - Developed a highly scalable TCP/IP communication server for statement printers.
key technologies used: C++ using STL and Boost libraries; multithreaded design using Windows NT's I/O completion ports for high scalability
