Schema Design
Complete database architecture for new applications or major redesigns. We begin with stakeholder interviews to understand your data domain, create entity-relationship models, implement appropriate normalization, define constraints and relationships, and document every decision for your development team.
Deliverables include DDL scripts, ER diagrams, data dictionary, and implementation guidance documentation.
Query Optimization
Analysis and improvement of slow-running queries. We capture production query patterns, examine execution plans, identify missing or unused indexes, restructure inefficient joins, and recommend configuration adjustments for your workload profile.
Typical engagements address the top 10-20 problematic queries with measurable performance improvements documented.
Database Migration
Safe, verified transitions from Oracle, MySQL, SQL Server, or other platforms to PostgreSQL. We assess compatibility, plan data type mappings, convert procedural code, execute migration with validation checkpoints, and verify data integrity post-migration.
Includes rollback procedures and parallel running strategies to minimize risk during cutover.
Indexing Strategy
Comprehensive analysis of your indexing landscape. We identify queries that would benefit from new indexes, locate unused indexes consuming storage and slowing writes, and recommend composite index structures for your most critical access patterns.
Balances read performance gains against write overhead and storage costs.
Database Audit
Health assessment of existing PostgreSQL installations. We examine schema design quality, index effectiveness, configuration settings, security posture, backup procedures, and replication health. Suitable for systems inherited from previous teams or those experiencing unexplained performance degradation.
Delivers prioritized recommendations with effort estimates.
Ongoing Maintenance
Monthly retainer for continuous database health monitoring and optimization. Includes regular performance reviews, proactive issue identification, minor schema modifications, query tuning, and priority access for urgent consultations.
Ideal for organizations without dedicated database administrators on staff.
