Real problems. Production-minded outcomes.

SQL Server to PostgreSQL migration within the delivery window

Challenge. The team needed to move a development platform from Microsoft SQL Server to PostgreSQL while preserving application compatibility and keeping delivery momentum.

Approach. Schema and data migration, compatibility remediation, application coordination, permissions, validation and operational handover were handled as one migration workstream.

Outcome. The environment moved to PostgreSQL within the planned working window and was returned ready for continued development.

Acceptance. The PostgreSQL environment was made available to the development team within the same working day, with schema/data movement, compatibility remediation and access validation completed as part of the handover.

High-availability database operations with production-first diagnostics

Challenge. A mission-critical Oracle RAC environment required resilient operations, performance investigation and clear separation between database symptoms and application-driven incidents.

Approach. RAC/Data Guard diagnostics, workload analysis, listener and connection-pattern investigation, storage controls and evidence-driven incident isolation.

Outcome. Operational issues were traced to their actual layer, remediation was targeted, and production continuity remained the priority throughout.

Acceptance. Incident evidence separated database symptoms from application behavior, enabling targeted remediation while preserving production continuity and avoiding speculative database changes.

Production-grade database architecture across multiple platforms

Challenge. Different workloads required the right combination of SQL Server, PostgreSQL, Oracle, Redis and DR patterns without forcing a single-platform answer.

Approach. Platform-specific HA/DR patterns, backup strategy, performance baselines, capacity planning and operational runbooks were designed around each workload.

Outcome. The estate gained clearer ownership, consistent operational controls and architecture aligned to workload requirements.

Acceptance. Platform-specific HA/DR, backup, recovery and operating controls were documented around the workload rather than standardized into a single unsuitable pattern.

Specific without exposing clients

Confidentiality matters. We describe real technical work without publishing customer names without permission.

Outcome before adjectives

What changed matters more than a generic claim that the work was innovative or world-class.

Production context

Architecture is judged by how it performs, recovers, scales and can be operated after handover.
