Kodo Labs

Rails engineering for new builds and rescues

A Ruby on Rails studio, Kodo Labs builds new web applications and repairs existing ones. New products built from scratch and older applications that still run a business but need careful attention both fall within its work. The company says it has 18 years of experience and more than 150 projects, and it describes its engineers as senior people who are accountable for every line of code.

Health checks and Rails rescues

A Rails health check is a written assessment of an application, delivered within five working days. It covers the Ruby and Rails versions in use and the security exposure that comes with them, along with dependency risk, test coverage and performance hotspots. The result is a prioritized upgrade path with effort estimates. The company says the assessment is credited in full against any engagement that follows. A rescue moves an older application onto a supported Ruby and Rails version, audits dependencies and applies the fixes, raises test coverage so future changes are safer, and sets up a continuous integration pipeline. A handover document explains what changed, what is still risky and what comes next.

Production AI features

For teams that want AI features in a product, the company scopes the feature, builds it and ships it to production. It adds an evaluation suite so quality is measured rather than guessed, monitors token costs with spend limits, and designs fallback behavior for when a model fails or times out. The client keeps ownership of the code and the repository.

SaaS platforms and dedicated squads

Multi-tenant platforms are architected for tenant isolation from the start, with single sign-on through SAML, role-based access control and audit logs. The build includes subscription billing, usage metering and self-serve onboarding, along with documentation and infrastructure that the client's own team can take over. Clients who prefer an embedded team can hire a dedicated squad of two engineers, a quality assurance specialist and a project manager, who work in the client's tools and process and are billed monthly.

Work in regulated and marketplace settings

The company describes an anonymous whistleblowing platform for employers, which it built from scratch in 2018 and still runs across the API and the mobile app. It also cites a two-sided marketplace for booking private chefs, where it launched the third build after two earlier attempts had not shipped, and an AI-driven account-based marketing platform for B2B sales teams. Its product information tool for Shopify merchants started from a slow, buggy codebase that was rebuilt.

How the team uses AI in delivery

The firm says it uses AI-assisted coding tools in daily delivery, but each change still passes through the usual review, test suite and senior sign-off applied to all other work.
