Debugging and fixing software problems in the company products that are in production
- I receive a problem from L2 Support in the company problem tracking system (namely CFS)
- make a first analyze, isolate the faulty module in the C++/SQL/Java part, based on traces/logs, SQL selects, Unix core debugging
- make a detailed analyze on the specific module, reading the related code
- write and test the fix (mostly in C++) if it takes less that 1 week. Escalate to Development if a longer development is needed
- build/deliver the fix to L2 Support, taking into account the dependencies with other modules
- writing/supporting testing tools - simulators, load test tools, automatic non-regression test tools
- coaching new members of the team - Software Integrator - Team leader at EservGlobal Telecom Romania, Bucharest - software outsourcing for www.eservglobal.com [LSE: ESG]

- coordinating a team of 9 software engineers: training, coaching and evaluating the engineers in the team. Acting as Technical Project Manager for Integration projects and L3 Support for the problems after deployment.
- working in a multinational environment, keeping daily contact with project managers in France, using email and phone (in English). Between other activities, my work included:
- I have run manual and automatic tests, including load test. I have debugged the encountered problems until the C++ or PL/SQL code, including performance problems due to the bad index usage. I have written Perl/Shell tools to ease the testing and analyze, including an automatic test framework based on plugins.
- As "Level 3 Support" tasks, I analyze problems discovered in site, including the creation of C++ patches. I have contribute in the analyze and solution for special C++ problems in Unix environment: TCP/IP sockets, signal handling in multithreading environment.
- I have installed and administrated 3 Solaris 5.8 servers. I have given support occasionally for Unix related software problems, like dynamic linkage, scripting, performance. I have setup Solaris 10 zones (with ZFS filesystem) to be used as virtual machines in Integration campaigns.
- I have installed/administrated 4 Informix database servers, starting with chunk allocation on raw devices or cooked files, multiple dbspaces for table and index fragmentation. I have performed database import/export, I have created tools for importing data on a different (compatible) database structure and for resizing the extents of an exported database.
- I have configured the Unix/Solaris test environments: packages, libraries, TCP/IP ports, message queues and shared memory allocation, environment variables.
- I have participated in the recruitment process for people in my team and 2 people in another team. I have done coaching and periodic evaluation for my team, I have participated in defining the global evaluation process. - Technical Coordinator for the Bucharest TCP/IP network (bussines unit) at Romania Data Systems, BUCURESTI

July 1999 - April 2005
I coordinated a team of 20 engineers in charge with the last level of support (L3/L4) for the TCP/IP network in Bucharest:
- more than 20 IP routers
- more than 200 intelligent (configurable) switches - with vlan tagging, electrical/optical links
- more than 10 Linux servers (Email, DNS, WEB, CRM, monitoring, provisioning)
- more than 20.000 broadband cable modems
- I had "hands on" experience in configuring/debugging Linux, Unix, Cisco 6500/3750/2900, Allied Telesyn routers and switches, Arris CMTS 1500 cable modem controllers
- I have worked in creating and administrating the "Ip over cable" and "Voice over cable" modem provisioning system, based on Docsis/MCNS technology. The provisioning system was created "in house". The system was able to automatically generate the configuration files using the database service definition.
- I acted as project manager for "in-house" soft projects (on Linux/Unix platform): WEB based CRM, network monitoring & reporting (MRTG/RRD tool based), data warehouse. I have defined the high level software architecture and database structure, I have contribute with solutions for critical performance issues, I have write medium size applications in C++, SQL, Perl.
- I have established/supervised the network topology evolution in a fast growing condition. I have established quality metrics regarding the network performance and upgrade priorities. I have established working procedures.
- I have occasionally meet strategic clients for defining the technical solution (presales)
- I have done recruiting and periodic evaluation for the engineers in my team.
