Christof Meerwald

Profile

Experienced developer specialising in C++ static code analysis, backed by a Master's degree in Computer Science. Versed in several programming languages (C/C++, Java and Python) on Unix and Win32 platforms. Able to come up with elegant solutions to tricky problems by thinking outside the box.

Work Experience

Programming Research Ltd.

• Static code analysis for C++

Emnico Technologies Ltd./Emnico Services Ltd.

• Network management application development -- concentrating on SMI parser, SNMP/MIB and native code integration for low-level network and OS access. Designed and implemented a versatile framework to access MIB data by auto-generating data-access functions from MIB module definitions.
  key technologies used: Java + JNI, XML + XSLT, Apache Derby, SNMP, MIB/SMI, low-level network access
• Developed an asynchronous TCP/IP communication server.
  key technologies used: C++, Boost
• Support and continuous development of an optical network management (SONET/SDH) system in a Unix environment (C++ on HP-UX and Linux).
  key technologies used: C++, CMISE, OSI
• Linux embedded software development.
  key technologies used: C/C++, SNMP, Linux, Python-based code generation
• 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, OSI
• 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
• Developed a scriptable test-client in Java/JavaScript to automate testing of an XML message based interface.
  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

Lebenshilfe Salzburg, Werkstätte Hallein

• As an alternative to Austria's compulsory military service: working with people with mental or multiple handicaps.

AT&T Laboratories Cambridge

• Automated and improved the omniORB regression testing suite; developed a black-box CORBA server testing tool in Python, based on annotations in the interface definition (IDL).

HTBLA Salzburg

Education

Skills and Interests

• Programming in C, C++ (including STL and some Boost libraries), Java (incl. JNI), Python (incl. Django) and PHP with the ability to quickly understand an already existing, complex code-base.
• Development for Linux/POSIX platforms and Win32.
• Strong understanding of multithreaded development (i.e. concurrency, race-conditions, contention, thread-local storage)
• Developed and currently running JabRSS, an RSS (RDF Site Summary) headline notification service for Jabber/XMPP.
• Developed a lightweight SIP forwarding server (stateless SIP proxy) as well as a lightweight exim greylisting server using a SQLite backend.
• Contributor to the Open Watcom C++ compiler: major improvements to the C++ front-end (i.e. partial template specialization and partial ordering of class templates, template functions, namespace support and general C++ standard compliance).
• Contributed Linux-specific epoll connection handling code to the Open Source jabberd2 XMPP server to improve scalability for high number of concurrent connections.
• Extended the firmware of the Linksys WRT54G wireless router to support OpenVPN and OpenSWAN.
• Linux server administration (based on Debian GNU/Linux and Ubuntu): Apache, bind, PowerDNS, CVS, DHCP, exim, Dovecot (IMAP/POP3), Squid, PostgreSQL, inn, NewsCache, OpenLDAP, Samba, Dante/Socks, Subversion, Quagga, Bird, Netfilter/IPTables Firewall, ...
• Network planning and administration: Virtual Private Network configuration using OpenVPN and OpenSWAN (IPSec-based); excellent knowledge of IP and IP-based protocols, including TCP, UDP, DNS, HTTP, NNTP, SMTP, SNMP, SIP, XMPP and IPv6.
• Open Source advocate familiar with many widely used Open Source licences (and with a good understanding of the implications of using Open Source software in a commercial environment).
