## Streamlit data apps that run in production

Internal dashboards, analytics tools, and data science UIs—hardened for real teams, not just demos.

## When Streamlit moves from prototype to internal product

Streamlit is the fastest route from a Python script to a shareable interface—but internal dashboards and data tools need more: scheduled data refreshes, warehouse connectors, caching that doesn't stall users, and role-based access. We take the working prototype and turn it into a tool your team actually relies on.

## What we deliver

- **Data pipeline and warehouse integration**: Direct connectors to Postgres, BigQuery, Snowflake, Redshift, or dbt models—with caching layers that keep dashboards fast without hammering your warehouse.
- **Multi-user auth and access control**: SSO via OIDC/SAML, role-based page routing, and session-safe state management so different teams see the right data.
- **Deployment, scheduling, and monitoring**: Containerised builds, Kubernetes or managed cloud runtimes, scheduled refresh jobs, alerting, and runbooks your ops team can follow.

## Engineering standards in production

How we keep Streamlit data apps fast and reliable

- **Caching strategy**: st.cache_data and st.cache_resource scoped correctly so queries are fast and memory stays bounded—not a global cache that silently serves stale numbers.
- **Reproducible builds**: Pinned requirements, Docker images tested in CI, and a clear separation between dev fixtures and production data sources.
- **State and session hygiene**: No cross-user state leaks. Session isolation tested explicitly—especially for apps that display sensitive figures.

## When engagement makes sense

- **Internal BI tool becoming a real product**: When the dashboard built for one analyst is now expected to serve a whole department with consistent, trusted numbers.
- **Warehouse or dbt model integration**: When the app needs to query production data, join models, and write results back—without a manual CSV export step.
- **Data team without ops bandwidth**: When the Python expertise is there but deployment, auth, and incident response are not the team's core skill.

## FAQ

- **Can you extend an existing Streamlit app?**: Yes—we start with a codebase review, agree a remediation and extension scope, and hand back a documented, tested version.
- **Can Streamlit replace our BI tool?**: For custom, code-driven analytics—yes. For self-service drag-and-drop exploration by non-developers, a BI tool is usually the better fit.
- **Fixed price?**: Possible for tightly scoped pilots. Open-ended or evolving dashboards suit a retainer or phased model.
