We engineer high-performance mobile apps and web platforms.
Code Room is an independent software consultancy. We partner with tech companies to ship cross-platform React Native products, build resilient TypeScript web applications, and optimize critical client-side performance.
Case Studies & Outcomes
Real engineering interventions where performance, architecture, and velocity mattered.
Cross-Platform FinTech Mobile Suite
Engineered a unified iOS & Android application replacing two fragmented legacy codebases. Implemented biometric auth, offline SQLite sync, and interactive high-frequency charts running at a consistent 60fps.
Real-Time Operations & Dispatch Platform
Architected a high-density operational dashboard handling high-frequency WebSocket updates. Eliminated re-render bottlenecks through fine-grained reactive state and optimized canvas map rendering.
React Native Performance & New Architecture Migration
Audited an enterprise mobile codebase, migrated legacy bridge dependencies to TurboModules and Fabric renderer, and reduced cold startup time from 2.8s to under 900ms on budget Android devices.
Embedded Mobile Core Team for HealthTech
Integrated two senior engineers into an in-house product team to lead HIPAA-compliant Bluetooth device communication and background sensor syncing on iOS and Android.
Core Capabilities
Cross-Platform Mobile Apps
Production React Native development from day one or modernization of existing mobile applications.
- Greenfield iOS & Android apps
- Expo & EAS Continuous Deployment
- Complex 60/120fps gesture systems
- Custom Swift & Kotlin native modules
Modern Web & SaaS Platforms
Scalable, resilient web applications built with React and strict TypeScript that don't crumble under load.
- Next.js & React 19 architecture
- Comprehensive design systems
- Sub-second LCP & Web Vitals audit
- Type-safe RPC & GraphQL layers
Audits & Team Acceleration
Direct senior bandwidth to resolve stubborn performance bottlenecks or accelerate delivery.
- New Architecture (Fabric/Turbo) upgrades
- Memory leak & frame rate profiling
- Automated CI/CD & release pipelines
- Embedded senior ICs (no juniors)
Technical Specialization
We do not claim to do everything. We specialize deeply in the modern JavaScript and TypeScript ecosystem.
Stack Philosophy
We avoid unnecessary dependencies, unproven hype, and heavyweight abstractions. Every library in our dependency graph has a justified performance and maintenance trade-off.

How We Partner
Direct Engineering Contact
You speak directly with the engineers writing your code. No layers of non-technical account managers filtering your requirements.
Predictable Two-Week Sprints
Working software demos and pull requests shipped every sprint. Clear burndown and production-ready staging builds.
Clean Code Ownership
You own 100% of the repository, documentation, CI scripts, and infrastructure from Day 1 with zero vendor lock-in.
Let's build something solid.
Whether you need to ship a new mobile product from scratch, audit existing performance, or augment your frontend team — tell us what you're building.
