Hire REST API Designers | Nearshore Software Development

A well-designed REST API is a critical asset for any modern business. It's the front door to your platform, and it needs to be clean, consistent, and easy to use. You need an expert who understands the principles of good API design and can create an API that your developers and partners will love. Our vetting process, powered by Axiom Cortex™, finds engineers who are masters of API design. We test their ability to design a resource-oriented API, to handle versioning and evolution, and to create clear and comprehensive documentation.

Is your API inconsistent, confusing, and difficult to use?

The Problem

An inconsistent and poorly documented API is a major source of frustration for developers, leading to slow integration times and a poor developer experience.

The TeamStation AI Solution

We vet for engineers who are experts in designing clean, consistent, and intuitive REST APIs. They must demonstrate a deep understanding of RESTful principles and the ability to create an API that is a pleasure to use.

Proof: Improved Developer Experience and Faster Integration
Are you afraid to make changes to your API for fear of breaking existing clients?

The Problem

Without a clear versioning and evolution strategy, your API can become a brittle monolith that is impossible to change without breaking your users' applications.

The TeamStation AI Solution

Our engineers are proficient in API versioning and evolution strategies. They are vetted on their ability to design an API that can evolve over time without breaking existing clients, ensuring a stable and reliable platform for your users.

Proof: Stable and Evolvable API Design
Is your API documentation always out of date?

The Problem

Manually writing API documentation is time-consuming and error-prone. It's almost guaranteed to become out of sync with the actual API implementation, leading to confusion and frustration for your users.

The TeamStation AI Solution

Our experts are masters of the OpenAPI Specification (formerly Swagger). We vet their ability to design APIs with a schema-first approach, which allows them to automatically generate interactive documentation, client SDKs, and even server stubs, ensuring your documentation is always accurate and up-to-date.

Proof: Accurate, auto-generated documentation with OpenAPI
Does your API lack a consistent error handling strategy?

The Problem

Inconsistent error responses make it difficult for client applications to handle failures gracefully. If every endpoint returns a different error format, developers are forced to write custom, brittle error handling logic for each one.

The TeamStation AI Solution

We hire engineers who understand the importance of a standardized error format. They are vetted on their ability to design and implement a consistent error response strategy (e.g., following RFC 7807 for Problem Details) across the entire API, simplifying error handling for all consumers.

Proof: A standardized and consistent error handling strategy

How We Measure Seniority: From L1 to L4 Certified Expert

Our Technical Analysis for REST API Design

The REST API Design evaluation focuses on the principles and practices of building high-quality APIs. Candidates are given a business domain and are required to design a complete REST API for it, justifying their design decisions. A critical assessment is their ability to design a clean and consistent resource model and to choose the appropriate HTTP methods and status codes. We also test their knowledge of API versioning strategies and their ability to document an API using the OpenAPI specification. Finally, we assess their understanding of API security best practices.
