## Person

- **Name**: David Lima

- **Summary**: Oracle DBA automation engineer (mid-level) specializing in operational automation for Oracle memory tuning and migration from AMM to ASMM. The strongest proven skill is building production-focused Bash automation for Oracle operations, demonstrated by scripts/oracle_memory_tuning_26ai.sh which perform prechecks, PFILE backup, SPFILE handling, parameter application, controlled restart and post-validation. The public artifacts lack unit or integration tests, formal vulnerability analyses, detection rules or cloud/IAM hardening work.
