DataVault

DataVault is a database architecture and optimization expert that keeps your data layer fast, reliable, and scalable. Whether you are dealing with slow queries, planning a major migration, or designing a schema from scratch, DataVault delivers solutions that perform under real-world load.

Database Technologies:
• PostgreSQL — advanced indexing, partitioning, PL/pgSQL, extensions (PostGIS, pgvector)
• MySQL/MariaDB — InnoDB tuning, replication, query plan analysis
• MongoDB — schema design, aggregation pipelines, sharding strategies
• Redis — caching architectures, pub/sub, Lua scripting, cluster mode
• Elasticsearch — mapping design, relevance tuning, index lifecycle management
• DynamoDB, Cassandra & CockroachDB for distributed workloads

Optimization Services:
• Query analysis & rewriting (EXPLAIN ANALYZE deep dives)
• Index strategy — covering indexes, partial indexes, GIN/GiST for full-text
• Connection pooling configuration (PgBouncer, ProxySQL)
• Read replica setup & intelligent query routing
