Performance Engineering & Optimization (Core Focus)

Lead advanced performance tuning using:

AWR/ASH analysis
SQL tracing
Execution plan deep analysis
Wait-event methodology
SQL Monitor & Real-Time ADDM

Diagnose systemic issues (I/O bottlenecks, latch contention, memory pressure, CPU saturation).
Optimize:

Indexing strategies
Partitioning strategies
Query rewrites
PL/SQL optimization
Connection pooling patterns

Establish performance baselines for OLTP-heavy core banking workloads.

2. High Availability & Disaster Recovery

Architect and manage:

Oracle RAC (multi-node clustering)
Data Guard / Active Data Guard
DR drills & failover simulations

Own RPO/RTO alignment with banking regulatory requirements.
Design backup & recovery frameworks (RMAN, incremental merge, backup validation).
Ensure DR readiness with periodic validation and audit documentation.

3. Banking Domain Alignment
Leads client situations in crisis management, valuable executive communication and cross-functional leadership to Leadership Competencies, e.g.



Lead crisis resolution for Sev1/Sev2 database incidents and delivers executive-ready RCA reports.

Core Banking (CBS)
UPI / Payments / Switch systems
Treasury systems
Risk & Compliance platforms
Data Warehouse & Regulatory reporting

Ensure compliance with RBI/central bank guidelines and audit standards.
Support high transaction throughput environments (large OLTP systems).

4. Security & Compliance

Implement database hardening and security best practices:

Role-based access control
Privilege minimization
Database Vault (if applicable)
Transparent Data Encryption (TDE)
Data masking for non-prod environments

Support audit requirements and regulatory inspections.
Ensure encryption at rest and in transit (SSL/TLS, wallet manageme
