Database Design & Development
High-concurrency database engineering: Relational schema design (PostgreSQL), NoSQL architectures, query indexing, pgvector semantic search, and zero-downtime data migrations.
What is Database Design & Development?
Poorly designed database schemas and unindexed tables are the #1 cause of application latency, locking deadlocks, and server crashes under load. As your data grows, sloppy queries bring entire applications to a halt.
We design robust, normalized, and high-performance database architectures using PostgreSQL and Prisma. We eliminate slow table scans, design row-level security policies, partition high-volume tables, configure pgvector semantic embeddings, and execute zero-downtime database migrations.
Eliminates slow sequential scans, reducing complex analytical query times from seconds to sub-20 milliseconds.
Enforces strict data separation at the database layer with zero risk of cross-tenant leakage.
Configured daily snapshot replication with automated failover and rapid disaster recovery.
What's Included in Every Project
Full-cycle software engineering deliverables designed for scalability, security, and performance.
Entity-Relationship Diagram (ERD) & Schema Blueprint
Visual schema model with foreign keys, constraint rules, and data dictionary documentation.
Normalized PostgreSQL Schema with Prisma ORM
Strictly typed TypeScript models, automated migration scripts, and seed data generators.
Query Execution Plan (EXPLAIN ANALYZE) Indexing
B-Tree, GIN, and composite indexing eliminating full table scans on high-traffic endpoints.
pgvector Semantic Vector Database Configuration
Vector embeddings storage and cosine distance similarity indexing for AI search applications.
Automated Off-Site Backups & Point-in-Time Recovery
Automated daily snapshot replication to Cloudflare R2 / AWS S3 with disaster recovery runbooks.
30-Day Post-Launch Warranty & Query Latency Benchmarks
Continuous performance monitoring and slow query log auditing.
Our 4-Step Software Delivery Process
Agile milestone sprints with continuous staging deployments and transparent reporting.
Data Requirements & Cardinality Audit
We analyze business entity relationships, read/write ratios, expected data volume, and query patterns.
Schema Normalization & ERD Design
We construct 3NF normalized relational schemas with strict data types, unique constraints, and foreign keys.
Indexing & Migration Script Build
We write Prisma migrations, create partial and composite indexes, and benchmark EXPLAIN query execution plans.
Zero-Downtime Migration & Backup Setup
We migrate data to production, configure automated off-site R2 backups, and verify query latency.
