Devlyn AI · Ruby on Rails · Hanoi
Ruby on Rails engineering for Hanoi teams.
Bypass the Hanoi talent shortage. Deploy a senior Ruby on Rails pod aligned to your time zone in 24 hours.
The intersection
Building Ruby on Rails teams in Hanoi is structurally constrained by local supply. Local FTE hiring in Hanoi is achievable but scaling a specialized team quickly is difficult. Pod retainers provide immediate burst capacity for critical roadmap items.
AI-augmented Rails workflows lean on Cursor and Claude Code for migration scaffolding with proper index and constraint definitions, controller-action patterns with strong-parameter handling, service-object and query-object extraction from fat models, test-fixture generation using FactoryBot with trait composition, and RSpec request-spec scaffolding — all under senior validation that owns architecture decisions, Active Record query performance review including eager-loading strategy and N+1 detection, security review on authentication (Devise configuration) and authorization (Pundit policies), and Rails-specific pitfalls like callback-chain complexity, migration rollback safety, and Sidekiq concurrency management. Compression shows up strongest in CRUD controller actions, migration authoring, and RSpec test coverage expansion.
Rails engagements at Devlyn typically run as one senior backend engineer plus shared DevOps for $4,500–$8,000/month, covering model architecture, API design, and Sidekiq job infrastructure. This scales to a two- or three-engineer pod when the roadmap splits into parallel lanes across Hotwire frontend work (Turbo Frames, Stimulus controllers), async-task and background-job infrastructure, and integration-heavy features requiring payment, CRM, or third-party API coordination. Pods share a single retainer with flexible allocation.
