Core SQL Service Offerings
How we support your SQL projects
Our SQL development services are grounded in fifteen years of experience architecting and managing complex database systems. Our solutions improve performance, ensure compliance, and support business-critical operations.
Performance Tuning & Rescue
When your application is slow and the database is the bottleneck, we find and fix the root cause. This is a deep-dive engagement focused on database optimization, query analysis, execution plans, and indexing strategies to restore performance to critical systems.
Architecture & Health Audit
Get a top-to-bottom review of your SQL environment. We deliver an actionable roadmap covering security vulnerabilities, high-availability and disaster recovery gaps, and scalability planning before they become critical failures.
Platform Modernization & Migration
Move from legacy databases (like Oracle, DB2) or outdated on-prem servers to a modern SQL environment, either on-prem or in Azure. We manage the entire migration process with minimal downtime.
BI & Data Warehouse Engineering
We build the reliable data backbone your analytics demand. This involves designing and implementing data warehouses, ETL/ELT pipelines, and optimized data marts to ensure tools like Power BI and Tableau are fed clean, fast, and accurate information.
Data-Centric Application Development
We design and build secure, scalable applications where the database is the core. This covers everything from the database schema and internal business logic (stored procedures, functions) to the data access layer used by your front-end applications.
Managed Database Services
We provide ongoing management of your database environment. Our SQL experts handle the day-to-day work of backups, security patching, performance monitoring, and proactive tuning, freeing up your internal team to focus on building features.
Our SQL development process
How we develop and deliver SQL projects
We’ve refined our process through years of managing mission-critical data systems. Every project is delivered with the same rigor and reliability you’d expect from a best-in-class software development company.
Strategic Discovery
We partner with stakeholders to define measurable data outcomes, identify architectural constraints, and establish the KPIs for performance, availability, and data quality that will define success.
Architecture & Data Strategy
We design resilient data architecture for today’s needs and future growth, choosing platforms and patterns (e.g., OLTP, OLAP, Data Lake) for optimal performance, security, and cost-effectiveness.
Database Delivery Engine Setup
We configure Git for schema versioning, CI/CD pipelines for automated migrations (using tools like Flyway or Liquibase), and isolated dev/test environments so your team can build safely from day one.
Prioritization & Backlog Management
We turn strategic goals into a clear, prioritized backlog of tasks—such as building a new data mart, optimizing a critical set of queries, or implementing a new security model—and plan sprints to deliver the most valuable work first.
Test-Driven Data Development
We use database testing frameworks (like tSQLt) to build reliable stored procedures, functions, and triggers. Automated data validation and integration checks prevent regressions and ensure data integrity with every change.
Continuous Security & Quality Analysis
We integrate automated scanners into the pipeline to detect security vulnerabilities (like SQL injection risks), identify anti-patterns in code, and check for configuration drift against established security benchmarks.
Automated Schema Deployment
We build and manage zero-downtime deployment pipelines for database changes. Using versioned migration scripts, we safely apply updates to production without disrupting users or data.
Production Monitoring & Alerting
We implement deep monitoring of production databases, tracking query performance, wait statistics, index health, and resource utilization. SLO-based alerts notify us of problems, often before they impact the business.
Continuous Performance Optimization
We analyze production monitoring data to proactively tune queries, optimize indexing strategies, and forecast capacity needs, ensuring the system remains fast and cost-effective as it grows.
Data Governance & Evolution
We establish and maintain data governance policies for security, compliance (e.g., GDPR), and data retention. We manage the platform's evolution, from routine patching to major version upgrades, to meet future challenges.
Custom SQL Databases for Core Business Systems
Where SQL fits in your architecture
SQL is the foundational data layer for nearly every critical system in the enterprise, from the front lines of customer-facing applications to the back office of analytics and reporting.
Transactional Backends for Core Applications
SQL is the operational heart of your most important web applications, ERPs, and CRMs. These systems demand strict ACID compliance, low latency, and high concurrency. We design normalized schemas, optimized indexing strategies, and efficient stored procedures to ensure your application's data layer is a fast, reliable source of truth that is never a bottleneck.
Data Warehousing for Business Intelligence
For analytics, SQL serves as the engine for your data warehouse. Raw transactional data is rarely suitable for reporting, so we engineer analytics-first data models using dimensional techniques (star schemas) and modern structures like columnstore indexes. This creates a clean, fast, and accurate backend for tools like Power BI and Tableau, enabling trustworthy, self-service reporting.
Master Data Management (MDM) Hubs
For large organizations, SQL provides the stable, governable core for a single source of truth. Disparate systems often create conflicting versions of critical data like "customer" or "product." We build centralized MDM databases that enforce data quality, consistency, and governance rules, providing a canonical source that all other applications can rely on.
Data Transformation and ETL/ELT Pipelines
In a modern data stack, SQL is a powerful engine for transformation. Data is often siloed and needs significant cleansing before it's useful. We use SQL-based tools—from traditional SSIS to modern platforms like dbt—to create reliable, repeatable data flows that validate, aggregate, and move data between systems.
Managed SQL in the Cloud (AWS, Azure, GCP)
Within your cloud architecture, SQL often runs as a managed Platform-as-a-Service (PaaS) offering. We are experts in the nuances of these services, including AWS RDS, Azure SQL, and Google Cloud SQL. We design for cost optimization, multi-AZ high availability, and robust security. Our work ensures your databases gain the full benefits of the cloud while avoiding common performance and security pitfalls.

Top 1% Database Engineering Talent
Our senior database engineers average 10+ years of experience and pass rigorous evaluations covering data modeling, performance tuning, high-availability architecture, and more. Need to rescue a high-throughput OLTP system, migrate a multi-terabyte data warehouse, or operate within strict HIPAA compliance? We staff specialists who have done it in production.
Time Zone-Aligned Teams
Our SQL engineers work in your timezone, eliminating the delays that slow offshore database projects. We address schema changes, query tuning, and production issues in real time, keeping your systems stable and your teams unblocked. Our nearshore model accelerates delivery while reducing the risks of downtime and missed deadlines. For you, it feels like adding senior SQL developers directly to your staff without the overhead of full-time hires.
