Development
Software development as a continuous stream
We build web and mobile platforms for regulated industries — version-controlled, observable, maintainable for the long run.
Capabilities
One engineering shop for six disciplines
From the web app to the backend infrastructure — one team, one stack, one delivery process. Every discipline lives in the same repository.
WebView apps
Native shell around responsive web apps — store distribution without duplicate work.
Capacitor · Native bridge
Hybrid apps
One codebase, two stores. Close to native, fast to market.
Ionic · Capacitor
Cross-platform
Real native performance via React Native and Flutter — shared logic, platform-specific polish.
React Native · Flutter
Backend
APIs, event pipelines and data models built for load and compliance.
Node · Postgres · K8s
DevOps & QA
CI/CD, telemetry, automated tests — delivery as a standard process.
GitHub Actions · OTel
Working style
Three engineering principles every commit follows
A steady delivery cadence, readable code, measurable impact — the quality baseline of every project.
- 01
Incremental delivery
Weekly releases instead of big-bang. Every change is small enough to roll out — or roll back — without drama.
- 02
Readability over cleverness
Code is read ten times more often than it is written. We optimize for clarity for future engineers, not for elegant one-liners.
- 03
Observability from day one
Every service ships with logs, metrics and traces. What is not measurable cannot be owned.
