About this service

Summary

I specialize in developing scalable, high-performance web backends using Elixir, leveraging its concurrency and fault-tolerant features to build efficient and reliable applications. From API development and real-time features to database design and microservices architecture, I ensure that every backend system I create is optimized for speed, scalability, and maintainability. Whether you need seamless integration, background job processing, or performance tuning, I deliver robust, production-ready solutions tailored to your specific needs. Let me help you build a backend that supports your growth and delivers top-tier performance.

What's included

API Development
RESTful or GraphQL API built with Elixir and Phoenix or any language per your requirement. Endpoint documentation (using tools like OpenAPI or Swagger). Data models and schema design. Integration with authentication (JWT, OAuth2, etc.). API versioning, and error handling strategies. Integration of background jobs and job queues (e.g., Oban or GenStage).
Database Design & Management
Database schema design (PostgreSQL, MySQL, or NoSQL). Efficient data models for scalability and performance. Database migrations and seed data scripts. Data caching and query optimization (using tools like Redis). Database indexing and tuning for performance.
User Authentication & Authorization
Secure authentication mechanisms (e.g., password hashing, two-factor authentication). Role-based access control (RBAC) or permission systems. OAuth2, JWT token-based authentication setup. Secure password reset and user management functionality. SSO (Single Sign-On) integration if required.
Microservices & API Integrations
Modular microservices architecture for scalability. Integration with third-party APIs (REST, SOAP, Webhooks, etc.). API client libraries for external integrations. Service orchestration with Elixir (using GenServer, Task, or Flow). Data synchronization between microservices (e.g., using RabbitMQ, Kafka).
Error Handling & Logging
Error and exception handling strategies in the codebase. Integration with error tracking services (e.g., Sentry, Appsignal). Centralized logging using Elixir’s Logger or external services (e.g., Loggly, ELK Stack). Graceful shutdown and recovery mechanisms. Logging for real-time troubleshooting.
Testing & Quality Assurance
Unit and integration test coverage for all APIs and services. Test suites using ExUnit, Mox, Chai, Mocha for browser automation. CI/CD pipeline setup for automated testing (GitHub Actions, CircleCI, etc.).
Documentation
Detailed project documentation (code, architecture, and API docs). Database schema documentation and migration guides. Developer setup guide for running the project locally. Post-deployment documentation and instructions for maintenance.
