Database Architecture
Data models, migration strategies and query optimization for production systems.
Overview
Your database is the foundation everything else sits on. Get it wrong and you spend the next two years working around bad schema decisions. We design data models that reflect your actual business domain, optimize query patterns for your real access paths and build migration strategies that let your schema evolve without downtime.
We work across relational databases, document stores, key-value caches and search engines. The choice depends on your data shape, access patterns and consistency requirements, not on what is trending on Hacker News.
Technical Details
Schema Design
Normalized relational schemas for transactional systems where data integrity matters. Denormalized read models for high-throughput query patterns. We design indexes based on actual query plans, not guesswork. Every table gets a documented purpose, and every foreign key relationship maps to a real business rule.
Migration Strategy
Zero-downtime schema migrations using expand-contract patterns. Version-controlled migration files that run in CI/CD pipelines. Backward-compatible changes deployed independently from application code. Rollback procedures tested before every production migration.
Performance Optimization
Query analysis using EXPLAIN plans and slow query logs. Index tuning based on actual production workloads, not synthetic benchmarks. Connection pooling configuration, read replica routing and caching layer design. We have cut query times from seconds to milliseconds on production systems serving millions of rows.
Multi-Store Architecture
PostgreSQL or MySQL for transactional data. Redis for caching, sessions and rate limiting. Elasticsearch for full-text search and analytics. Firebase or MongoDB for document-oriented data. Each store chosen for its strengths, with clear data flow between them and consistency guarantees documented.
