Hire SQLAlchemy Experts | Nearshore Software Development

SQLAlchemy is the Python SQL toolkit and Object Relational Mapper that gives application developers the full power and flexibility of SQL. You need an expert who can wield SQLAlchemy to build high-performance, maintainable data access layers. Our vetting process finds Python developers who are masters of SQLAlchemy. We test their ability to use both the high-level ORM for rapid development and the low-level SQL Expression Language for fine-grained control and performance.

Is your ORM hiding the power of SQL from you?

The Problem

Many ORMs abstract away SQL to the point where it's difficult to write complex, high-performance queries, forcing you to drop down to raw SQL and lose the benefits of the ORM.

The TeamStation AI Solution

We vet for engineers who are experts in SQLAlchemy's layered approach. They must demonstrate the ability to use the full power of the SQL Expression Language to build any query imaginable, while still benefiting from the convenience of the ORM where appropriate.

Are you struggling with database connection management and transactions?

The Problem

Properly managing database connections, sessions, and transactions is a complex task that can easily lead to bugs and performance issues if not handled correctly.

The TeamStation AI Solution

Our engineers are proficient in SQLAlchemy's Session and Engine management. They are vetted on their ability to design a robust and efficient connection management strategy, and to correctly handle transactions to ensure data consistency.

Core Competencies We Validate

SQLAlchemy Core and SQL Expression Language
ORM patterns and declarative mapping
Session and transaction management
Relationship configuration and loading strategies
Alembic for database migrations

Our Technical Analysis

The SQLAlchemy evaluation is a deep dive into Python database programming. Candidates are required to build a data access layer, demonstrating their ability to use both the ORM and the Core Expression Language. A critical assessment is their understanding of the Session lifecycle and how to manage transactions correctly. We also test their knowledge of different relationship loading strategies and their performance implications. Finally, we assess their experience with Alembic for managing database schema migrations.
