About this service

Summary

I specialize in building scalable, secure, and high-performance back-end services primarily using Node.js, GraphQL, and PostgreSQL. My unique strength lies in architecting robust cloud-native solutions, including real-time integrations and complex API integrations on platforms like AWS and DigitalOcean, ensuring your applications are future-proof and reliable.

Process

From concept to deployment, here's how we'll bring your backend vision to life:

Requirement Analysis & API Design: We'll define your application's data flow, identify key features, and design efficient API contracts (REST or GraphQL) that meet your specific needs.

Database & Schema Implementation: I'll create a robust database schema using PostgreSQL and integrate it with Prisma ORM to ensure data integrity and optimal performance.

Backend Development: I'll write clean, modular, and secure code using Node.js and Express.js or Apollo Server, implementing business logic, authentication, and necessary integrations.

Testing & Optimization: Rigorous testing (unit, integration, and API testing) will be performed to ensure stability and catch any bugs. I'll also optimize for performance and scalability.

Deployment & Monitoring: Your backend will be deployed to a reliable cloud environment (AWS or DigitalOcean) with CI/CD pipelines for automated updates. I'll set up basic monitoring to keep an eye on performance.

Documentation & Handoff: You'll receive comprehensive API documentation, codebase overviews, and instructions for managing your deployed services.

What's included

Scalable & Secure API Development
This core deliverable provides the foundation for any dynamic application. I build robust and well-documented APIs (both RESTful and GraphQL) that are designed for high performance and security, handling everything from user authentication to complex data operations. Format: Functional, tested API endpoints deployed to a staging or production environment. Quantity: A complete set of API endpoints as defined in the project scope. Revisions: Includes a round of revisions based on API specification reviews and a final testing phase to ensure functionality and security. Details: Built primarily with Node.js and Express.js or Apollo Server (GraphQL), incorporating JWT Authentication, RBAC (Role-Based Access Control), and adhering to best practices for data security.
Optimized Database Design & Integration
A strong backend relies on a well-structured database. I design and implement efficient database schemas, ensuring data integrity and optimal performance for your application's data storage and retrieval needs. Format: Implemented database schema, migrations, and ORM configurations. Quantity: 1 integrated database solution. Revisions: Database schema refined during the development phase, with necessary adjustments based on data modeling reviews. Details: Utilizes PostgreSQL for relational data management, with Prisma ORM for efficient and type-safe database interactions, ensuring a robust data layer.
Backend Deployment & CI/CD Pipeline
Beyond just code, this deliverable ensures your backend services are live, stable, and can be updated seamlessly. I set up the cloud infrastructure and automation necessary for continuous integration and deployment. Format: Access to the deployed backend services and a functional CI/CD pipeline. Quantity: 1 deployment setup and 1 automated CI/CD pipeline. Revisions: The deployment process and pipeline are thoroughly tested to ensure smooth operation. Details: Services deployed on AWS or DigitalOcean, configured with GitHub Actions for automated build, test, and deployment workflows, providing a reliable and efficient release process.
