Cloud-native Architecture
Context
The situation before the platform
Why drug-free therapy needed a connected ecosystem rather than a device on its own.
| The business |
A healthcare provider bringing non-invasive, high-frequency neurostimulation to patients living with acute and chronic pain, together with the clinicians who follow those patients through treatment. |
| The starting point |
The starting point |
| The trigger |
Patients had to visit clinics or hospitals frequently for treatment. That created demand for a portable, easy-to-use option that fits into daily life without constant medical visits. |
| What they wanted |
One connected healthcare ecosystem where patients control therapy sessions, customise treatment parameters and monitor progress through a mobile-enabled interface, with reliable therapy delivery behind it. |
| Constraints |
The interface had to be simple enough for patients and clear enough for healthcare professionals managing sessions · device and application had to stay synchronised for consistent therapy delivery · secure cloud infrastructure and patient safety standards had to be part of the architecture, not a later addition. |

The engineering problem
Five gaps that shaped the build from day one
Not vague pain points — the specific tensions in moving pain therapy out of the clinic and onto a connected device, each paired with what we did about it.
0
1
Traditional pain treatment addressed symptoms, not the signal
Patients found that medication-led pain management offered short-term relief rather than addressing the root cause. Repeated usage became the norm, which made long-term pain management frustrating and inconsistent.
What we did
Built the platform around high-frequency neurostimulation that interrupts pain signals before they reach the brain, working at a neurological level rather than masking the discomfort.
0
2
Medication brought nausea, drowsiness and dependency risk
Pain medication often came with unwanted side effects such as nausea, dizziness and constant drowsiness. Over longer periods there was also a risk of dependency, affecting patients' overall health and quality of life.
What we did
A drug-free therapy pathway delivered entirely through the connected device, so pain can be managed without opioids or other addictive medication and without the associated side effects.
0
3
Injections and surgery meant risk and long recovery
For many patients, managing pain meant injections, surgery or other invasive treatments. Those approaches carried higher medical risk and required longer recovery, disrupting daily life and adding stress.
What we did
Delivered therapy as controlled electrical impulses through the skin — a completely non-invasive route, without the discomfort or extended recovery periods that come with medical intervention.
0
4
Pain varies by person; the treatment did not
Most existing pain management options followed a single fixed approach. Because pain differs greatly between individuals and affected areas, the absence of tailored options made it hard for patients to get relief that matched their condition.
What we did
Personalised therapy controls for intensity, duration and stimulation frequency, so each patient can fine-tune treatment to their own condition. Therapy workflows and stimulation settings were optimised against different patient needs.
0
5
Therapy that required a clinic visit every time
Frequent trips to a clinic or hospital were time-consuming and inconvenient. What was needed was a flexible, easy-to-use and portable option letting people manage pain comfortably without constant medical visits.
What we did
A connected IoT ecosystem where patients access and manage therapy sessions from a smartphone or tablet, with wireless connectivity keeping the device and application in continuous communication.
Architecture
How it fits together
Simplified — the shape rather than every service.
0
1
Clients
Flutter · iOS & Android · Angular.js web · Chart.js reporting
A Flutter application gives patients one cross-platform therapy interface on phones and tablets, with an Angular.js web experience for follow-up views and Chart.js rendering therapy progress.
0
2
Gateway
Laravel API layer · Authentication & · IoT integration
A Laravel API surface handles authentication, patient and clinician roles and every client request, and is the point where IoT device traffic joins the rest of the platform.
0
3
Services
Therapy session control · Device synchronisation · Treatment parameters · Progress monitoring · Wireless connectivity
Each function is its own concern, so session control, device synchronisation, parameter management and monitoring can be tuned or extended without destabilising therapy delivery.
0
4
Data & infra
PostgreSQL · AWS · AWS EC2 · AWS S3
PostgreSQL holds patient, session and therapy configuration data, with the platform running on AWS EC2 and S3 so secure cloud infrastructure scales as the connected device base grows.
Reliable therapy delivery was treated as an architectural requirement rather than a tuning exercise: a scalable, secure structure and continuous wireless communication are what keep device and application synchronised through a session.
Solutions
Six systems doing the actual work
Not a features list — the specific things we built behind every number above.
High-frequency neurostimulation therapy
Therapy designed to interrupt pain signals before they reach the brain, working at a neurological level rather than masking discomfort.
Drug-free treatment pathway
An alternative to medication and invasive procedures, so patients manage pain without opioids, side effects or surgical risk.
Personalised therapy controls
Patients adjust therapy intensity, duration and stimulation frequency to match their own condition and the area affected.
IoT-enabled therapy access
A connected ecosystem where therapy sessions are reached and managed from a smartphone or tablet, at home, at work or while travelling.
Device synchronisation
Reliable synchronisation between therapy device and application, so settings and session state stay consistent through treatment delivery.
Remote therapy management & monitoring
Sessions, treatment settings and device connectivity managed through one digital ecosystem, with progress visible to patients and the clinicians following them.
Key features
What the platform does day to day
Five capabilities, each closing one of the gaps identified above.
| Capability | Runs | Refresh | What it does |
|---|---|---|---|
| IoT-enabled therapy access | PATIENT - INITIATED | On demand | Lets patients reach neurostimulation therapy through a connected smartphone |
| Device synchronisation | PAIRED DEVICE | Continuous | Keeps therapy device and application in step for smooth treatment delivery |
| Remote therapy management | CONNECTED ECOSYSTEM | Per session | Manages therapy sessions, treatment settings and device connectivity remotely |
| Personalised treatment controls | PATIENT - CONFIGURED | Before each session | Supports customisation of therapy intensity, duration and stimulation frequency |
| Wireless device connectivity | WIRELESS LINK | Real time | Maintains continuous communication between therapy devices and the application |

INTO THE CORE SERVICES ↓
Core services
Therapy sessions
Treatment parameters
Device sync
Progress monitoring
Patient records
Because session control, treatment parameters and monitoring resolve against the same services, a patient starting a session, adjusting intensity and reviewing progress are three steps in one interface rather than three separate systems.
Security
What protects patient and therapy data
The platform carries patient information, therapy settings and session history — so protection was designed in, not bolted on.
Secure cloud infrastructure
Therapy and patient data sit on secure cloud infrastructure, built into the architecture from the start so data safety and reliable performance hold together.
Role-based platform access
Patients, healthcare professionals and administrators each reach only what their role requires when managing therapy sessions and treatment settings.
Validated device communication
Testing covered accurate device synchronisation and secure system performance, so device and application stay in step through a therapy session.
Patient safety standards in QA
Extensive testing and validation at every stage covered application stability, consistent therapy delivery and high standards of safety for patients.

Business impact
What changed for the business
Beyond the headline numbers, three things patients and clinicians noticed first.
Therapy that travels with the patient
A connected ecosystem replaced the clinic visit as the default route to treatment, making therapy reachable wherever the patient happens to be.
A patient experience people rate well
The intuitive interface, personalised treatment controls and non-invasive approach together shifted how the treatment feels to use day to day.
Less reliance on medication
A drug-free pathway gave patients a route to relief that does not depend on pharmaceuticals, reducing exposure to side effects and dependency risk.
Commercial outcome
What the engineering choices are worth in operating terms
Every headline number traces back to a specific decision, not a vague platform effect.
| Engineering decision | Operating outcome | Measured effect |
|---|---|---|
| Personalised therapy controls & optimised stimulation settings | Treatment matches the individual condition instead of one fixed pattern | 45% better pain management efficiency |
| IoT-enabled therapy access from phone or tablet | Therapy reachable at home or while travelling rather than only in clinic | 40% more treatment accessibility |
| Device synchronisation & in-app session control | Starting a session takes taps rather than a manual setup routine | 50% less treatment setup time |
| Drug-free neurostimulation pathway | Relief without opioids or other addictive medication | 35% lower medication dependence |
