Our stack for
scalable products
Relational Databases
We work across the full range of enterprise-grade relational database engines and match the right technology to your workload, compliance, and cost profile.
SQL Dialects & Programming
Each database engine has its own procedural language. Our engineers work fluently across the dialects your systems depend on.
Cloud-Native Database Services
Managed database services accelerate delivery and reduce operational overhead. We design cloud-native database architectures on the major providers.
Data Modeling & Design
Solid data models age well. We design schemas and data architectures that handle change without expensive rewrites.
Performance & Optimization
Performance in databases is more than fast queries. We tune the full pipeline, from indexes to execution plans to hardware, for consistent behavior under load.
Data Integration & Pipelines
Databases rarely stand alone. We integrate SQL systems with the broader data ecosystem for reporting, analytics, and application use.
Security & Compliance
Databases hold the data that matters most. We design access controls, encryption, and audit practices aligned with the compliance frameworks your business depends on.

About Development
SQL and relational databases remain the backbone of modern software, powering everything from transactional systems and fintech platforms to reporting layers and analytics warehouses. Despite the rise of NoSQL and modern data stacks, SQL is still the language most business-critical data speaks, and the engineers who can design, tune, and maintain it are among the most important on any technology team. Companies looking to hire SQL developers benefit from access to specialists across database design, query optimization, DBA operations, and cross-engine expertise, plus the discipline to keep data systems running reliably in production for years.
A well-designed relational data layer improves transaction integrity, reporting accuracy, performance, and operational resilience. Strong SQL expertise also helps teams prevent expensive bottlenecks before they affect customers or downstream analytics.
Relational databases support transactional applications, BI and reporting layers, data warehouses, financial systems, healthcare records, e-commerce catalogs, multi-tenant SaaS products, and operational platforms with complex data relationships.
Our database teams work across SQL Server, PostgreSQL, MySQL, Oracle, Aurora, Azure SQL, Cloud SQL, Redshift, Snowflake, stored procedures, replication, backup tooling, monitoring, and infrastructure automation.
SQL and NoSQL solve different problems. Relational databases give you strong consistency, ACID transactions, and mature tooling, while NoSQL offers flexible schemas and horizontal scale. Most production systems today use both, SQL for transactional and structured data, NoSQL for high-throughput or unstructured workloads. Our engineers know when to choose each and how to design architectures that use both effectively.

Development FAQs
How senior are your SQL developers?
All our SQL developers, DBAs, and database engineers are pre-vetted senior professionals with at least 5 years of production experience. They've built and optimized database systems for fintech, healthtech, retail, and B2B SaaS clients across multiple industries.
Can your SQL developers integrate into our existing workflows?
Yes. Our developers join your standups, follow your sprint cycles, use your tools (Slack, GitHub, Jira, Linear), and work in your time zone. You manage them as part of your team while we handle payroll, hardware, and operations.
Which database engines do your SQL developers work with?
Our team works across the full relational database ecosystem: Microsoft SQL Server, PostgreSQL, MySQL, Oracle Database, and SQLite, plus cloud-managed services like Amazon RDS, Aurora, Azure SQL Database, and Google Cloud SQL. We match developers to your specific engines, dialects, and use cases.
Can you help us with SQL performance tuning and slow queries?
Yes. SQL performance tuning is one of our core services. Our engineers audit execution plans, redesign indexes, refactor slow queries, and optimize the full data pipeline to eliminate bottlenecks. We turn database performance from an ongoing headache into a predictable engineering practice.
Do you work with T-SQL, PL/SQL, and stored procedures?
Yes. We work across all major SQL dialects, including T-SQL (SQL Server), PL/SQL (Oracle), and PL/pgSQL (PostgreSQL). Our engineers design and maintain complex stored procedures, functions, and triggers, and modernize legacy procedural code where it makes sense.
Can you migrate between database engines or move databases to the cloud?
Yes. Database migrations are one of our core services. We plan and execute migrations across engines (e.g., Oracle to PostgreSQL, SQL Server to Aurora), and from on-premise to cloud-managed services, with parity testing and zero-downtime strategies to keep your business running through the transition.
Can you support HIPAA, SOC 2, or PCI-compliant database environments?
Yes. We design database environments aligned with HIPAA, SOC 2, PCI DSS, and other compliance frameworks. As an ISO 27001:2022 certified partner, we protect your data with encryption, access controls, and audit practices from day one.
What does it cost to hire SQL developers through Devlane?
SQL engagement cost depends on seniority, specialization (development, DBA, performance tuning, architecture), and engagement length. Our nearshore model is typically 40-60% lower than hiring senior SQL talent in the U.S., with one all-inclusive rate covering salary, benefits, equipment, and management.
How fast can an SQL developer start?
Most engagements start within 2-3 weeks. We pre-vet candidates from our network of 70,000+ professionals, so you interview only SQL programmers for hire that match your database engines, seniority, and use case.
