REFERENCES
  • WORK EXPERIENCE:
 
Petrobras (Brazilian Oil and Gas company) – since Oct 2006
  • Application (ABAP and SQL) tuning, coaching development teams. Some critical business processes had their runtime dropped from hours to just some seconds, allowing the business to grow with the same infrastructure.
  • SAP TDMS 4 technical implementation leader – installation, configuration, monitoring, tuning, troubleshooting. Scenarios implemented : System Shell, Time Slice for ERP, Transfer of Master/Customizing data for ERP and Transfer of PA/PD data (HCM). For some cases it reduced the time to get data to solve defects in production system from more than one week to just one hour
  • SAP LVM 2.1 technical implementation leader – installation, configuration, troubleshooting, management of other IT teams (storage, VM, OS). Scenarios implemented : Stop/Start with dependencies and custom hooks/operations, ABAP/Java application server installation, Rename System and Post-Processing Standalone. With these scenarios the number of human resources needed for typical Basis activities dropped from several people to just one.
  • Infrastructure team leadership in a project responsible for separate Petrobras Chile ERP system´s company code and related data into new systems using SAP SLO. Activities included management of different infrastructure teams : SAP Basis, Database, Hardware and Storage.
  • Implementation of Oracle Fine Grained Auditing, reducing the amount of audit records from 40GB/day to just 10KB/day, and as a consequence, also reducing the overall overhead on the database server.
  • Support for SAP ECC 6.07 (nearly 10.000 concurrent users in production and over 10 systems in the landscape), SAP CRM 7.02
  • Support and troubleshooting for Opentext Archive Server (IXOS) in a solution to manage its integration with SAP, regarding data archiving and imaging files, in a EMC Centera device. This solution reduced the storage cost due to the high compressed data done by Centera – rate 5:1 on average.
  • Typical SAP Basis activities, like installations, maintenance of multi-landscape environments through client copies, system refreshes and transport management, system and kernel upgrades, support packages installation, SAP notes, TMS configuration
