Case studies
The need, what we built, and what changed. Sorted by the kind of problem, not the technology.
Operations and payments
Staff checked every clinician by hand on the HHS site, a compliance requirement for per-diem placement.
An integration that pulls the full exclusion list internally and screens new and existing clinicians on a recurring schedule.
A manual compliance task became an automated, repeatable check.
Clinicians were paid through manual bank transfers after each shift.
A Branch API integration that pays out on shift approval, plus custom Bubble.io plugins for Stripe subscriptions and clinician payments.
Same-day payment straight to clinician wallets or bank accounts.
Background check orders waited on manual activation by staff.
A Simply Verified integration where clinicians order and pay for their own checks.
No activation bottleneck, and faster profile approval.
Payment, compliance and credentialing systems all push events into the platform.
Webhook pipelines with HMAC signature validation and OAuth 2.0 client-credentials integrations.
Every third-party endpoint is verified before it touches business data.
Data and integrations
Clinicians’ physical addresses had to be verified and shifts geofenced without slowing the platform down.
A proprietary .NET serverless service on Azure Functions for geolocation identification, address verification and geofencing.
Higher throughput, with responses down to 4 ms.
The agency needed a public job board that stays in sync with its job feed.
A WordPress job board with custom PHP plugins, ingesting postings through the Jobrobotix API.
2,000+ live postings refreshed every 5 minutes.
Agency systems and facility-side workforce management did not talk to each other.
A bidirectional integration with Symplr’s contingent talent management VMS.
Data now flows both ways between the agency and its facilities.
Production staffing workflows needed reliable event processing and data pipelines.
Azure Data Factory for orchestration, .NET Azure Functions for event-driven processing and Storage Accounts for persistence. I supervised deployments and service health.
Monitored uptime across environments for the agency’s production systems.
Field and industrial
Field measurements had to reach the platform wirelessly, without mains power, from inside an explosion-proof enclosure.
A battery-powered Zigbee wireless transmitter, with custom antenna assemblies that integrate with an Ex d enclosure while keeping its flameproof barrier intact.
Wireless field data on a battery runtime of 7 years.
Remote oil and gas field operations needed reliable long-range telemetry and real-time data.
Hardware for a custom Zigbee gateway: schematics and multi-layer PCB layouts optimised for signal integrity and power efficiency in harsh industrial environments.
Reliable long-range telemetry and real-time data ingestion across remote oil and gas field operations.
New field instruments had to interface with existing industrial signals and protocols.
Prototypes covering sensor integration and signal conditioning, 4–20 mA, RS-485 and Modbus interfacing, component selection and BOM development.
Functional prototypes, validated through bring-up and bench testing with firmware and manufacturing partners.
Traditional C-based embedded systems were slow to change for non-critical applications.
IoTech’s first IIoT gateway on Node.js and Angular, including a Modbus port to the Node.js runtime.
The proof of concept was adopted internally as a standard approach.
IoTech’s SCADA platform needed its first operator interface.
An Angular and TypeScript frontend on a customised PrimeNG library, an ISA 18.2 alarm UI on ag-grid, Gridstack dashboards with Chart.js and Highcharts charts, and Protobuf decoders for live MQTT data.
An MVP that consumes live MQTT data in the browser.
Most of these started as a single sentence from a client. Send me yours.
