Web Data Modeling and Database Design

Design optimal database index strategies for PostgreSQL, MySQL, and MongoDB to accelerate query performance, reduce scan costs, and balance read/write overhead.

Audit and refactor existing database schemas to eliminate redundancy, fix normalization violations, and improve data integrity through systematic table restructuring.

Create clear, accurate ER diagrams in Mermaid, dbdiagram.io, or notation-standard formats to document data models, communicate schema design, and support team collaboration.

Design Neo4j and property graph data models for web applications requiring relationship-centric data — covering node labels, relationship types, properties, and Cypher query patterns.

Design multi-tenant database architectures for SaaS web applications — covering tenant isolation strategies, shared schema patterns, row-level security, and data partitioning.

Design MongoDB, Firestore, and DynamoDB document models with embedding vs. referencing strategies, indexing plans, and query-optimized data structures for web apps.

Design ORM model definitions, relationships, and migration files for Prisma, TypeORM, Sequelize, SQLAlchemy, and ActiveRecord in production web application projects.

Design time-series database schemas and storage strategies for web applications using TimescaleDB, InfluxDB, or PostgreSQL partitioning to handle high-volume temporal data efficiently.

Plan and script safe, reversible database schema migrations for web applications — covering zero-downtime strategies, rollback paths, and data transformation logic.
