Services
Design & Development
Full-cycle web application development — from initial meeting to production launch. Deep requirements analysis and domain modeling. Architecture design built to withstand growth and change.
Every feature is covered by tests. CI/CD is configured from the first commit to make deployment predictable and safe. Code is written so any Rails developer can maintain it six months later.
Iterative approach: short cycles, frequent demos, fast feedback. This reduces risks and allows adapting to changing requirements without losing time or budget.
- Requirements and business logic analysis
- Architecture and database design
- Backend development with Ruby on Rails
- External API integration
- Test coverage
- CI/CD pipeline setup
- Deployment and monitoring
- Documentation and knowledge transfer
Project Support
Applications require constant attention after launch: dependency updates, security patches, adapting to new framework versions.
Regular releases, error and performance monitoring, prompt bug fixes. The stack stays current and the application runs stably under load.
- Ruby, Rails, and dependency updates
- Error monitoring and alerts
- Bug and incident resolution
- Security patches
- Regular releases
- New feature development
- New service integrations
- Monthly project status reports
Performance Optimization
A slow application loses users and money. Comprehensive performance audit: database query profiling, N+1 query detection, bottleneck analysis in business logic and infrastructure.
SQL query optimization, application and database-level caching, background processing for heavy operations. Horizontal scaling with load balancing when needed.
The result is measurable improvement: response time, throughput, resource consumption. Every optimization is backed by before-and-after metrics.
- Performance profiling and audit
- SQL query and index optimization
- Cache configuration
- Background job optimization
- Horizontal scaling
- PostgreSQL and web server tuning
- Before/after metrics report
Refactoring & Maintainability
Codebase audit, identifying problem areas, and developing a step-by-step refactoring plan. Without stopping development and without "rewriting everything from scratch."
The result: reduced technical debt, faster feature development, fewer bugs. Code that's a pleasure to work with.
- Codebase and architecture audit
- Step-by-step refactoring plan
- Domain logic extraction (Bounded Context, Service Objects, Form Objects, ...)
- Code smell and duplication removal
- Increasing test coverage
- Migration to current versions
- Architecture decision documentation
