Ruby on Rails backends and APIs.
We build Rails applications for relational data, background jobs, and transactional integrity. When the platform needs backend services, we add them alongside the frontend.
the problem
(01) Complex relational data
Frontend shops stall on race conditions, constraints, and multi-model transactions that need real backend design.
(02) Unreliable background work
Webhooks, syncs, and emails fired inline from request cycles fail silently under load with no retry story.
(03) Traffic spike fragility
Unindexed queries and missing connection discipline turn launches and campaigns into outages.
approach
(01) Clean Rails API design
We build versioned, documented APIs with strong parameters, service objects, and request specs from day one.
(02) PostgreSQL discipline
Indexes, constraints, and query profiling protect transactional integrity as data and traffic grow.
(03) Redis and Sidekiq queues
Background workers with retries and dead-letter queues absorb spikes in syncs, emails, and webhooks.
(04) Dockerized deployments
Reproducible containers with automated test suites ship the same artifact from CI to production.
scope
(01) Documented, versioned high-concurrency API backend
(02) PostgreSQL schema with indexes and integrity constraints
(03) Sidekiq worker queues with retry and monitoring configuration
(04) Automated test suite and Dockerized deployment setup
Fixed scope, fixed timeline. You keep the report and the roadmap whether or not we build the fix.
why 2sh
Direct systems engineering versus traditional front-end agencies.
| dimension | 2sh | traditional agencies |
|---|---|---|
| Backend depth | Rails APIs with transactions, queues, and documented contracts | Serverless functions glued to third-party services |
| Data integrity | Constraints and indexes designed before scale hurts | Schema designed in the frontend CMS |
| Reliability | Retries, dead-letter queues, and test coverage standard | Happy-path code with no failure story |
| Operators | Engineers who operate production Rails daily | Frontend team outsourcing the backend |
