Data you can trust, queries that stay fast.
Schema design, query optimization, zero-downtime migrations and scaling on PostgreSQL, SQL Server and MySQL — by engineers who treat your data as what it is: the heart of your business.
Database development covers designing, optimizing and evolving the databases behind your software: schema design, query optimization, migrations without downtime, scaling and backup strategies. Done properly on PostgreSQL, SQL Server or MySQL, it determines whether your application stays fast and your data stays intact as the business grows.
For Swiss SMEs whose applications have grown faster than their database: software slowing down, reports timing out, migrations everyone fears, backups nobody has ever tested. Also for teams starting a new product who want the data model right from day one.
Every application stands on its database. When the schema is sound, everything else gets easier: features ship faster, reports run instantly, migrations stop being feared events. When it isn't, every sprint pays the tax.
We design, optimize and evolve databases on PostgreSQL, SQL Server and MySQL — schema design, query tuning, zero-downtime migrations, scaling and tested backups — for brand-new products and for systems that have been running for fifteen years.
Why the database quietly decides your software's future
Every application stands on its database. When the schema is sound, everything downstream gets easier: features ship faster, reports run instantly, and changes stop being scary. When it isn't, every new feature pays a tax — slow queries patched with more hardware, workarounds stacked on workarounds.
Schema decisions made in week one are still shaping performance ten years later. That is why we put senior engineers on data modelling, whether we are designing a new product's database or untangling one that has grown organically since 2010.
Fixing slow: how we optimize an existing database
We never guess. Optimization starts with measurement: query plans, slow-query logs, lock contention, real production load. The findings usually rank clearly — a handful of queries and missing indexes typically cause most of the pain.
Then we fix in order of impact: indexes and query rewrites first, then structural changes where the model itself is the bottleneck. You get before-and-after numbers for every intervention, in writing — not an invoice and a promise.
Migrations without holding your breath
The word migration makes teams nervous because they have seen one go wrong. It doesn't have to be that way. We engineer migrations as code: versioned, tested against a copy of production, reversible, and executed with zero-downtime techniques so the business never notices.
This applies to schema changes, engine upgrades, and moves between systems — SQL Server to PostgreSQL, on-premises to a Swiss or European cloud — including for applications built by someone else.
Backups that actually restore
A backup that has never been restored is a hope, not a backup. We set up backup strategies with automated restore tests, defined recovery objectives, and integrity checks that catch silent corruption before it spreads.
For data covered by the nLPD, we also make sure of where the data — and its backups — physically live, with Swiss or European hosting when your obligations require it.

Schema decisions made early shape performance for years.
Most slow applications are slow databases — and most are fixable with measurement, not hardware.
Migrations can run without downtime when engineered, not improvised.
A backup that was never restored is a hope, not a backup.
