SQL Without Query Bottlenecks
Develop PostgreSQL, MySQL, and SQL Server backends with queries that stay fast as tables grow and traffic spikes.
👋 Talk to a database expert.
Trusted and top rated tech team
Databases that handle the load
Your application is fast until the database isn’t. Queries that worked fine with thousands of rows crawl with millions. Missing indexes, inefficient joins, and poor schema decisions compound as data grows. We build SQL backends with schema designs, indexing strategies, and query patterns that handle production load without becoming the thing that slows everything else down.
Our capabilities include:
- Schema design and data modeling
- Query optimization and performance tuning
- PostgreSQL, MySQL, and SQL Server development
- Database migrations and version upgrades
- Indexing strategies and execution plan analysis
- Stored procedures and data layer architecture
Who we support
Database problems compound. A slow query becomes a timeout becomes a user complaint becomes a fire drill. We fix the root cause.
App Teams With Slow Queries
Your application response times keep climbing and the database is the bottleneck. Queries that ran in milliseconds now take seconds, users notice, and nobody on your team knows how to read an execution plan or fix the indexing.
Companies Outgrowing Their Schema
Your data model made sense when you started but doesn't fit how the business works now. Tables have grown unwieldy, relationships are awkward, and every new feature requires workarounds instead of clean data access.
Teams Managing Multiple Databases
You run PostgreSQL for some services, MySQL for others, maybe SQL Server for legacy apps. Each has its quirks, and your team can't be expert in all of them. You need engineers fluent across platforms.
Ways to engage
We offer a wide range of engagement models to meet our clients’ needs. From hourly consultation to fully managed solutions, our engagement models are designed to be flexible and customizable.
Staff Augmentation
Get access to on-demand product and engineering team talent that gives your company the flexibility to scale up and down as business needs ebb and flow.
Retainer Services
Retainers are perfect for companies that have a fully built product in maintenance mode. We'll give you peace of mind by keeping your software running, secure, and up to date.
Project Engagement
Project-based contracts that can range from small-scale audit and strategy sessions to more intricate replatforming or build from scratch initiatives.
We'll spec out a custom engagement model for you

Our engineers work across PostgreSQL, MySQL, SQL Server, and other relational databases, matching platform choice to your requirements.
- PostgreSQL — Open-source database with advanced features like JSONB, full-text search, window functions, and extensibility for complex application requirements
- MySQL — Widely deployed relational database with strong replication support, InnoDB storage engine, and broad framework compatibility
- Microsoft SQL Server — Enterprise database platform with T-SQL, robust tooling, Always On availability groups, and deep integration with .NET ecosystems
- MariaDB — MySQL-compatible fork with performance improvements, additional storage engines, and active open-source development
- Oracle Database — Enterprise RDBMS with PL/SQL, advanced partitioning, RAC clustering, and features for high-volume transactional workloads
- SQLite — Embedded database for mobile apps, local storage, and lightweight applications that need SQL without a server process
Query Analysis & Optimization Tools
Curotec uses execution plan analyzers and profiling tools to identify slow queries and indexing gaps before they impact users.
- EXPLAIN & EXPLAIN ANALYZE — Query plan commands that reveal how databases execute queries, showing scan types, join methods, and cost estimates
- pg_stat_statements — PostgreSQL extension that tracks query execution statistics, identifying the slowest and most frequently run queries
- MySQL Performance Schema — Instrumentation for monitoring query execution, wait events, and resource consumption in MySQL databases
- SQL Server Query Store — Built-in feature that captures query history, execution plans, and performance metrics for regression analysis
- pgBadger & pt-query-digest — Log analysis tools that parse slow query logs and generate reports on query patterns and performance outliers
- Database IDE Tools — DataGrip, DBeaver, and Azure Data Studio for query development, plan visualization, and database exploration
Schema Migration & Version Control
We manage schema changes with migration tools that version database structures and deploy safely across environments.
- Flyway — Version-controlled migrations using SQL scripts with support for PostgreSQL, MySQL, SQL Server, and other databases
- Liquibase — Database change management with XML, YAML, or SQL changelogs, rollback support, and diff-based schema comparison
- Alembic — Python migration framework for SQLAlchemy projects with autogenerated migrations and branch support for parallel development
- Rails Migrations — Ruby on Rails schema management with reversible migrations, database-agnostic syntax, and rake task automation
- Prisma Migrate — TypeScript-first migration tool that generates SQL from schema definitions and tracks migration history
- dbmate & golang-migrate — Lightweight migration runners for Go projects and polyglot teams needing simple, framework-agnostic tooling

FAQs about our SQL development services
How do you approach query optimization?
We start with execution plans to understand what the database is actually doing. Most slow queries come from missing indexes, inefficient joins, or subqueries that could be rewritten. We fix the root cause rather than adding hardware.
Can you help if we don't know why our database is slow?
Yes. We profile query patterns, analyze wait statistics, and review schema design to identify bottlenecks. Often teams know performance is bad but lack the diagnostic expertise to pinpoint where and why.
Can you optimize RDS and Azure SQL?
Yes. Managed databases simplify operations but still require proper indexing, query tuning, and schema design. We optimize performance within the constraints and capabilities of your managed platform.
How do you handle production schema changes?
We use migration tools like Flyway or Liquibase with version-controlled scripts, test changes against production-like data volumes, and deploy during low-traffic windows when downtime isn’t an option.
Can you migrate us to a different database platform?
We migrate between PostgreSQL, MySQL, SQL Server, and others. This includes schema translation, data type mapping, query syntax conversion, and testing to ensure the application works correctly on the new platform.
What if our team wrote the queries and the schema?
That’s most of our clients. We review what exists, identify the specific problems, and fix them without judgment. Every team makes schema decisions that seemed right at the time.
