Software and mobile
development
SDEN designs and ships production web platforms, SaaS applications, and native and cross-platform mobile apps: from a blank page to App Store, Play Store, and live production.
What this domain covers
Our largest practice: web platforms, native iOS and Android, cross-platform mobile (Flutter, React Native), and the back-end services behind them.
We take a product from a blank page to a live release, or pick up a stalled codebase and rebuild it without losing the logic already baked in.
The stack is deliberately boring: Next.js, TypeScript, and React on the web, PostgreSQL for data, Node on the API, native Swift or Kotlin only where the product earns it. The rule: pick what your team can still maintain in three years, not what trended last quarter.
Software and mobile development: the SDEN defaults
Defaults we ship
- TypeScript end-to-end (no untyped boundaries between server and client)
- Component-driven UI with a shared design system
- Server-rendered by default; client-rendered only where interactivity demands it
- App Store and Play Store releases automated through CI
Deliverables
- Architecture decision record (ADR) for every non-trivial choice
- End-to-end typed API contract between front-end and back-end
- CI/CD pipeline that builds, tests, and deploys on every commit
- Documentation written for the next engineer, not the project manager

Retrieval-augmented generation grounds AI answers in your data. What RAG is, when it beats fine-tuning or a plain prompt, and what separates a knowledge assistant you can trust from a demo.
AI agents for business: where they work, and where a workflow wins
Agents are powerful and easy to get wrong. When a task genuinely needs an agent, when a plain workflow is the better answer, and how to keep an agent safe and affordable in production.
