PostgreSQL Development and Database Design Services

PostgreSQL development services for products that depend on their data: schema design, query and index tuning, migrations, replication and the application code around them. Senior engineers, AI-accelerated delivery, and a database your team understands and owns.

What We Serve

PostgreSQL Databases Designed for the Product, Not Just the First Release

Most database trouble is designed in early and discovered late. A table that mixed three ideas, a missing constraint, a report that scans every row: none of it hurts at a hundred customers and all of it hurts at ten thousand. Our PostgreSQL development services start from how the product reads and writes, then build a schema with the right keys, constraints and indexes, versioned migrations that run the same in every environment, and queries measured against realistic data before release. We work on managed platforms such as Amazon RDS, Aurora, Supabase, Neon and Cloud SQL, or on servers you run yourself. AI tools draft migrations and tests; senior engineers decide the model and review every change. The API and front-end can be built by the same studio, so the database is designed with the screens that use it.

Our Approach

Measure First, Model Carefully, Change in Small Steps

On an existing database we begin with evidence: the slowest statements, lock waits, table and index sizes, and what the application is really asking for. On a new one we begin with the domain and write the access patterns down before the tables. Every change is a reviewed migration with a tested way back. Large tables are altered without long locks, new indexes are built concurrently, and heavy changes are rehearsed on a copy of production. Backups are restored on a schedule to prove they work, and monitoring ships with the first release, not after the first incident.

What Is PostgreSQL Development?

PostgreSQL development covers designing, building and maintaining applications on PostgreSQL, the open source relational database. It includes the data model, SQL and application queries, performance, security, backups and the migrations that let the database change safely as the product grows.

Schema and data modelling

Tables, keys and constraints that keep data correct by design.

Queries and indexes

SQL and index choices measured with real query plans.

Migrations and releases

Versioned, reversible changes applied without downtime.

Reliability and security

Replication, backups, roles and row level security.

At Devoq Design, PostgreSQL development means a documented, tested data layer delivered about 5x faster, with senior engineers reviewing every migration.

Why Professional PostgreSQL Development Matters

Application code can be rewritten in a sprint. Data outlives every rewrite. A sound PostgreSQL design is the part of a product that pays back for years.

Correct Data

Constraints and transactions stop bad records at the source.

Speed at Scale

Indexes, partitioning and pooling planned for real volumes.

Zero-Downtime Change

Schema changes that do not lock the product.

Recoverable

Backups and point-in-time recovery that are tested, not assumed.

Secure by Role

Least-privilege roles and row level security where it fits.

One Database, Many Jobs

JSON, full-text, geospatial and vector search in one engine.

Flexible Engagement

One-off audit, fixed-scope project, retainer or a dedicated engineer.

Common PostgreSQL Problems We Fix

Teams usually look for PostgreSQL development services when the database has started to set the pace of the product. These are the problems we fix most.

Queries That Slow Down Every Month

Sequential scans and missing indexes on growing tables.

Migrations That Lock the App

Schema changes that block writes during business hours.

Too Many Connections

Serverless functions exhausting the pool under load.

A Schema Nobody Trusts

Duplicated columns, missing constraints and orphaned rows.

Backups Never Tested

A recovery plan that exists only on paper.

Stuck on an Old Version

Upgrades postponed because nobody owns the risk.

Frequently Asked Questions

What do PostgreSQL development services include?

Database design and data modelling, SQL and application queries, index and performance tuning, versioned migrations, replication and backups, security roles, version upgrades and migration from other databases. Devoq Design also builds the Node.js or Python services and the front-end that sit on top of the database.

Can you speed up our slow PostgreSQL database?

Usually, yes. We start with a performance audit: the slowest statements, their query plans, index usage, table bloat, locks and connection behaviour. Most gains come from a small number of indexes, query rewrites and pooling changes, and each one is measured before and after so the result is visible.

Should we use PostgreSQL or MongoDB?

PostgreSQL suits most business products: related data, transactions, reporting and strict correctness, and it also stores JSON when a part of the model is flexible. MongoDB suits document-shaped data that changes shape often or is read as whole documents. We recommend one after looking at your access patterns, and we build on both.

Can you migrate our database to PostgreSQL without downtime?

For most systems the visible downtime can be reduced to a short, planned switch. We copy the data, keep it in sync with change capture or replication, compare both sides, rehearse the cutover on a copy of production and keep a rollback path open until the new database has proved itself.

How much do PostgreSQL development services cost?

It depends on the size and state of the database, the number of services that use it, uptime requirements and whether the work is an audit, a new build or a migration. After a short discovery call we scope a fixed price for defined work or a monthly retainer for ongoing support.

How is this about 5x faster than a traditional agency?

Four things add up: several AI-drafted options at once instead of one at a time, generated boilerplate and tests instead of hand-written setup, reusable component libraries instead of page-by-page builds, and automated checks on every change instead of a manual pass at the end. Review time stays the same; waiting time disappears.

Is AI-assisted work good enough, and is it safe?

AI never ships anything on its own. A senior lead reviews every design and every code change, automated tests and accessibility checks run on each one, and the code is plain TypeScript in your own repository. We do not send your customer data to AI tools without a written agreement.

Who owns the code, the design files and the accounts?

You do, from the first week. Figma, GitHub, CMS and hosting accounts are created under your company, and the contract assigns the IP to you. There is nothing to hand back at the end because it was always yours.

How do you charge: fixed price, monthly retainer or dedicated team?

All three, depending on the shape of the work. A fixed price when the scope is clear, a monthly retainer when the work keeps evolving, and a dedicated designer or engineer pair when you want capacity inside your own team. We recommend one after a short discovery call.

Do you work with companies in the US, UK, Canada or Australia?

Yes, most of our clients are there. Devoq Design has teams in India, Canada and the US, so every project has overlapping hours for reviews and stand-ups. Everything else runs async with recorded walkthroughs, decision logs and written updates in your Slack or Teams.

How do we get started?

Book a 30-minute call or send a short brief. We come back within a few working days with a scope, a plan and a price. Work starts after an NDA and IP assignment are signed and your accounts are set up.
