PostgreSQL Development Services
PostgreSQL is my default database for anything with real relational data — orders tied to customers, bookings tied to resources, anything where data integrity actually matters. It's mature, well-documented, and handles both simple CRUD and complex relational queries without the workarounds a document database often needs for the same job.
This covers schema design, query optimization, and connecting Postgres reliably to a Node.js or Next.js application layer.
What's Included
- checkSchema design with proper normalization and foreign key relationships
- checkIndexing strategy based on actual query patterns
- checkQuery optimization for slow endpoints
- checkConnection pooling configuration for serverless or high-concurrency environments
- checkMigration tooling for versioned schema changes
When Postgres Is the Right Call
Any application where data has real relationships — a booking tied to a customer and a resource, an order tied to line items and a customer — benefits from a relational database's ability to enforce those relationships and query across them efficiently. Document databases can work, but usually end up re-implementing relational features informally once the data model grows past something trivial.
Frequently Asked Questions
PostgreSQL or MongoDB?add
PostgreSQL for anything with clear relationships between entities — which is most business applications. MongoDB can be a reasonable fit for genuinely document-shaped, loosely structured data, but that's a smaller share of real projects than it's often used for.
How do you handle connection limits in serverless environments?add
Connection pooling (via PgBouncer or a managed pooler like Supabase's) so serverless functions, which can spin up many concurrent connections, don't exhaust the database's connection limit.
Can you optimize an existing slow database?add
Yes — usually starting with EXPLAIN ANALYZE on the slowest queries to see what's actually happening, then adding indexes, restructuring queries, or denormalizing specific hot paths where it's justified.
