A performant API core
A SaaS that has outgrown its prototype backend and needs services that hold up under real traffic.
CH.02 · SOFTWARE
Custom Software & Applications
Software built to last — backends, frontends, and mobile engineered for performance, and legacy systems modernized without losing what already works.
We build software the way it should be maintained — typed, tested, understood.
This division delivers production software end to end: performance-critical services in Rust and Go, accessible web frontends in React and Vue, native mobile where the experience demands it, and disciplined modernization for systems that cannot simply be thrown away.
The through-line is longevity. We favour code you can reason about, interfaces that stay clean as they grow, and migrations that preserve data and continuity — so what we ship is still an asset years from now, not a liability someone inherits.
Service lines
Four disciplines, one engineering standard.
CH.02 / 01
Rust / Go Backend
High-performance backend services in Rust and Go — memory-safe, concurrent, and predictable under load. For APIs, real-time systems, and anything where latency and reliability are non-negotiable.
- Typed, tested, documented APIs
- Concurrency without the footguns
- Built for throughput and low latency
CH.02 / 02
React / Vue Frontend
Interactive web frontends engineered for speed and accessibility, with component architecture and state management that stay maintainable as the product and the team grow.
- Accessible, standards-based UI
- Fast initial load and interaction
- Design-system-driven components
CH.02 / 03
Native Mobile
iOS and Android applications built native for platform-grade performance, offline behaviour, and full access to device capabilities — not a web view in a wrapper.
- Native performance and feel
- Offline-first where it matters
- Store-ready release pipelines
CH.02 / 04
Legacy Modernization
Aging systems refactored or re-platformed into secure, maintainable architectures — incrementally, with data and continuity preserved, so the business keeps running through the transition.
- Incremental, strangler-pattern cutover
- Data migration with integrity checks
- Documented, testable replacement
Where it fits
Typical situations this division is built for.
USE / 01
USE / 02
A native app launch
A brand or product that needs a real mobile app — fast, offline-capable, and store-ready.
USE / 03
Replacing legacy
An organization stuck on an unmaintainable system that must be modernized without a risky big-bang rewrite.
