   reporting, cloud infrastructure, CI/CD and observability.

3. **AI consultancy.** Applied machine learning for health and other regulated

   what a system should not be asked to decide.

4. **Privacy and clinical safety engineering.** Data minimisation designed into

Additional senior full-stack engineers can be embedded alongside an existing

## Capability matrix

| Capability | Standard or technology | Why it matters |
|---|---|---|
| Health data interoperability | HL7 FHIR, REST/JSON | Records move between your system and an EHR without a bespoke adapter per partner |
| Clinical coding and terminology | SNOMED CT, ICD-10 | Conditions and procedures recorded in terms other systems and auditors understand |
| NHS supplier assurance | DTAC, DSP Toolkit | Procurement evidence exists before it is asked for |
| Clinical risk management | DCB0129 | Hazards identified and logged as process, with a clinician in the loop |
| Data protection engineering | UK GDPR, DPA 2018 | Lawful basis, retention and erasure enforced in schema and code |
| Mobile applications | Kotlin/Android, Swift/iOS | Native performance, offline behaviour, accurate store data-safety declarations |
| Web and full-stack | TypeScript, React, Python | One team from interface to database |
| Data platforms | Pipelines, warehousing, reporting | Reporting traceable back to the source record |
| Cloud and reliability | CI/CD, IaC, observability | Reversible releases, failures visible before users report them |
| Applied AI | Retrieval, grounding, evaluation | Output traceable to a source and measured against a test set |

## Assurance — held

- Registered with the Information Commissioner's Office (ICO) as a data
  controller.
- NHS Data Security and Protection Toolkit completed and passed.
- Led by a doctor registered with the General Medical Council (GMC).

## Assurance — in progress or not held

- Clinical Safety Officer training is in progress; the final course is
  outstanding and the qualification is **not yet held**. Where DCB0129 requires a
  Clinical Safety Officer, we work with a named external CSO.
- **No** ISO 27001, SOC 2 Type II, Cyber Essentials, FDA clearance, UKCA or CE
  marking is held or claimed.

## Own products

- **VocalCalm** — https://www.vocalcalm.com — a voice-first AI coaching
  application for iOS and Android. Users speak with an AI voice coach in focused
  thirty-minute sessions and finish with a concrete next step. Nine established
  coaching approaches are available, or the app suggests one.

## Typical clients

Health technology companies, clinical teams, digital health startups, and
organisations supplying software into the NHS.

## How we work

- Collect less. The safest record is the one that was never written.
- The privacy policy, the store declaration and the source code should describe
  the same system.
- Ship in small, reviewed, reversible pieces.
- Clinical caution beats product enthusiasm; some decisions do not belong to
  software.

## Scope and limits

eHealth Systems does not provide medical advice, diagnosis, or regulated clinical
services, and does not sell a medical device. It builds and advises on the
software that clinicians and health teams rely on.
