PostgreSQL Database Development Services

We use PostgreSQL as our default relational database for most new projects — open-source, deeply capable, and proven at massive scale.

Why choose PostgreSQL

PostgreSQL has become the default relational database choice for a large share of new applications, and for good reason — it combines rock-solid ACID compliance with a feature set that rivals or exceeds commercial databases (JSON/JSONB support, full-text search, geospatial queries via PostGIS, materialized views) without licensing costs. For nearly any application that needs structured, relational data with strong consistency guarantees, PostgreSQL is a safe, capable, and cost-effective default.

What we build with PostgreSQL

  • Core transactional databases for SaaS, fintech, and e-commerce applications
  • Multi-tenant database architectures for B2B SaaS products
  • Geospatial data systems using PostGIS (logistics, real estate, location-based apps)
  • Hybrid relational/document data models using JSONB columns
  • Read-replica architectures for high-traffic reporting and analytics
  • Full-text search implementations without needing a separate search engine

Our approach

We design PostgreSQL schemas with normalization principles applied thoughtfully — not dogmatically — denormalizing specific tables where read performance genuinely benefits and the data integrity tradeoff is acceptable. We implement proper indexing strategies from the start (not as an afterthought when queries get slow), use connection pooling (PgBouncer) for applications with high connection volume, and set up monitoring to catch slow queries before they become production incidents. See our data engineering service for analytics-scale workloads.

Scaling PostgreSQL

PostgreSQL scales further than most teams expect with proper architecture — read replicas for reporting workloads, partitioning for very large tables, and careful query optimization typically take a single PostgreSQL instance much further than teams assume before they need to consider sharding or a different database entirely. We help you scale the database you have correctly before recommending a more complex architecture you may not need yet.
