Ruby on Rails Backend Developer

Ruby on Rails backend developer focused on building, deploying, and maintaining production web applications. I work primarily on backend systems involving APIs, authentication, database design, and server-side logic, with experience operating applications in real production environments.

I enjoy owning backend features end-to-end—from database schema design through API implementation and deployment—and improving existing Rails codebases with maintainable, convention-aligned solutions.

• Ruby on Rails backend development
• RESTful API design and implementation
• Authentication and authorization systems
• PostgreSQL database design and optimization
• ActiveRecord modeling and schema design
• Production deployment and debugging
• Maintaining and extending existing Rails applications

Backend: Ruby, Ruby on Rails Databases: PostgreSQL, SQLite APIs: REST, JSON-based services Architecture: MVC, ActiveRecord, service-layer patterns DevOps / Tools: Git, GitHub, CI/CD workflows, Fly.io, Linux Supporting Technologies: JavaScript (integration-level use)

I have built and deployed multiple Ruby on Rails applications to production environments, where I have been responsible for backend functionality, database design, and system behavior under real usage conditions.

My work includes:

• Designing relational database schemas for application data models
• Implementing authentication and role-based access systems
• Building REST APIs for frontend and service communication
• Deploying and maintaining Rails applications in production environments
• Debugging runtime issues, migrations, and dependency problems
• Working within existing Rails codebases and extending functionality safely

A Ruby on Rails application featuring:

• User authentication and account management
• Persistent memory system with controlled storage limits
• Input filtering and moderation logic
• Backend systems designed for stateful interactions

Focus: backend state management, authentication, and system behavior control.

A full Ruby on Rails application implementing:

• CRUD functionality for blog posts
• Database-backed content management system
• Standard Rails MVC architecture
• Production deployment and runtime configuration

Focus: Rails conventions, data modeling, and application structure.

A RESTful backend API built with Rails featuring:

• Authentication and access control
• Input validation and structured JSON responses
• Controlled update permissions
• Data integrity and backend rule enforcement

Focus: API design, security rules, and backend correctness.

I focus on building backend systems that are:

• maintainable and convention-aligned
• structured around clear data models
• reliable under production constraints
• easy to extend within existing Rails applications

I am comfortable working in both greenfield and existing codebases, especially where feature ownership and backend responsibility are required.
