Hire Scalatra Developers: Affordable, Dedicated Experts in 72 hours

Scalatra is a minimalistic web framework for Scala, offering simplicity and flexibility for building RESTful services. A proficient Scalatra developer typically:

• Defines Routes & Actions: Maps HTTP verbs to handler functions using concise DSL syntax.
• Handles JSON: Integrates with libraries like Circe or Jackson for request/response marshalling.
• Manages Concurrency: Uses Futures, Cats Effect, or Akka Streams for non-blocking IO.
• Connects to Data Stores: Employs Slick, Doobie, or JDBC for database interactions.
• Configures Middleware: Adds authentication, session management, and CORS filters.

• Microservice-Friendly: Lightweight footprint ideal for service-oriented architectures.
• Functional Paradigm: Leverages Scala’s type safety and immutability for robust code.
• Minimal Boilerplate: Quick to set up and easy to maintain small codebases.
• High Performance: Non-blocking IO and asynchronous processing for high throughput.
• JVM Ecosystem: Access to mature libraries for testing, logging, and monitoring.

• Scala & sbt: Build tool configuration and dependency management.
• Scalatra Core: The framework for routing and handling web requests.
• JSON Libraries: Circe, Jackson, or Play JSON for data serialization.
• Database Access: Slick, Doobie, or Anorm for relational persistence.
• Async & Streams: Futures, Cats Effect IO, or Akka Streams for reactive IO.
• Testing: ScalaTest or Specs2 for unit and integration tests.
• CI/CD: Jenkins, GitHub Actions, or GitLab CI for automated builds and deployments.
• Monitoring: Prometheus, Grafana, or JVM metrics for service health.

• Scala Proficiency: 2+ years writing idiomatic Scala code.
• Functional Programming: Strong grasp of immutability, monads, and typeclasses.
• Web Frameworks: Experience building routes, filters, and middleware in Scalatra.
• Concurrency: Asynchronous programming with Futures or effect types.
• Database Integration: Building CRUD APIs using Slick or Doobie.
• API Design: REST principles, versioning, and error handling.
• Testing & QA: Writing comprehensive unit and integration tests.
• Soft Skills: Clear communication, agile collaboration, and documentation.

Job Title: Scalatra Developer, Scala Backend Engineer

Role Summary: Build and maintain RESTful APIs using Scalatra; integrate with JSON libraries and databases; and implement non-blocking, high-performance services.

Required Skills: Scala, sbt, Scalatra, Circe/Jackson, Slick/Doobie, Futures/IO.

Soft Skills: Problem-solving, clear documentation, and teamwork.

• Route & API Development: Define endpoints and handlers in Scalatra.
• Data Integration: Connect to relational or NoSQL stores for persistence.
• Asynchronous Processing: Use Futures or effect types for non-blocking calls.
• JSON Marshalling: Serialize and deserialize request/response bodies.
• Testing: Write unit, integration, and performance tests.
• Performance Tuning: Profile and optimize service throughput.

• Experience: 2+ years in Scala and Scalatra web services.
• Functional Expertise: Deep understanding of FP concepts and async patterns.
• Database Skills: Hands-on with Slick, Doobie, or equivalent.
• Testing Tools: ScalaTest or Specs2 proficiency.
• Soft Skills: Effective communication and agile practice.

• Cloud Deployment: AWS/GCP experience deploying Scala services.
• Streaming: Familiarity with Akka Streams or fs2 for data pipelines.
• No-Risk Trial: Provide a small Scalatra service implementation for evaluation.

Detail remote, hybrid, or on-site options; competitive salary or contract rates; benefits such as continued education stipends.

Outline steps: resume screening, code exercise (build a Scalatra endpoint), technical deep dive on FP and async, and culture-fit interview.

• Framework Niche: Validating true Scalatra experience versus generic Scala skills.
• FP Rigor: Assessing mastery of functional programming in practical services.
• Async Expertise: Ensuring candidates can handle real-world concurrency patterns.

• How do you structure route definitions and middleware in Scalatra?
• Describe handling JSON serialization with Circe and error handling.
• Explain implementing non-blocking database calls using Futures or IO.
• What strategies do you use to manage backpressure in data streams?
• How do you write integration tests for Scalatra endpoints?

• Provide Starter Project: Share a minimal Scalatra template with basic routes.
• Pilot Task: Assign adding a new API and database model.
• Document Standards: Share coding conventions, sbt configurations, and deployment guides.
• Mentorship: Pair with a senior Scala engineer for code reviews.
• Regular Demos: Weekly walkthroughs of new endpoints and performance benchmarks.

• Vetted Experts: Access top Scalatra developers with proven track records.
• Flexible Engagement: Hire freelance, contract, or full-time talent with a no-risk trial.
• Rapid Onboarding: Quickly integrate experts into your Scala codebase and workflows.
• Dedicated Support: Leverage project managers for seamless coordination.
• Global Network: Tap into diverse functional programming specialists across time zones.

Scalatra offers a lightweight path to build high-performance Scala web services, but success depends on developers who master its DSL, asynchronous patterns, and functional principles.
