Optimize your release process at scale
We help enterprise teams remove bottlenecks in their React Native release workflows. From CI/CD optimization to OTA rollout strategies, we redesign release systems to support faster delivery with shorter feedback loop and faster error recovery time.
Why release speed and scalability are a constant tradeoff in large React Native teams
As apps grow and more teams contribute, releasing React Native app becomes harder to coordinate. Without a scalable delivery process—from CI/CD to observability—teams are forced to choose between speed and control, often compromising both.
Slow feedback loop
Slow builds, unstable test runs, and missing automation delay validation. Teams often wait hours to get confidence in a single pull request, slowing delivery and increasing risk.

No release automation
Without flexible strategies for staging, OTA updates, and platform-specific rollouts, teams are forced into slow, manual release cycles. This limits their ability to react quickly.

Siloed monitoring and analytics
Errors and performance regressions often go unnoticed until users report them. Without integrated monitoring and alerting tied to releases, teams lose visibility into production impact.

Accelerating Expensify’s mobile build pipeline with custom CI/CD caching
To improve Expensify’s mobile delivery speed, we implemented a custom CI/CD build caching solution tailored to their React Native app structure. This optimization enabled faster release cycles, improved developer feedback loops, and reduced resource costs associated with redundant builds.

Ship faster with our open-source React Native Enterprise Framework
React Native Enterprise Framework (RNEF) was created to solve the real-world challenges of scaling React Native inside large organizations—making builds faster, simplifying infrastructure, and giving teams full ownership over their delivery pipeline.
- Runs on your infrastructure, under your control
- Ready for complex apps and large engineering organizations
- Drop-in replacement for React Native Community CLI
Optimize your React Native release process for speed and control
Release React Native features faster
We work with your teams to shift new feature development toward shared components and logic, enabling faster rollout without requiring changes to legacy areas of the app.
Lower crash rates with faster feedback loop
By integrating automated tests, pre-release validations, and monitoring into the delivery flow, we catch issues earlier and reduce production crash rates over time.
Recover faster from production errors
We work with your teams to shift new feature development toward shared components and logic, enabling faster rollout without requiring changes to legacy areas of the app.
Increase release frequency
By pairing a release and testing strategy with granular feature flags and targeted A/B tests, we help your team ship smaller changes continuously while keeping quality high and risk low.
