Platforms ready to deploy

01Manufacturing & Industrial Automation

Shop-floor systems, plant ERP, and the control layer underneath them.

Automated Mould Storage & Retrieval System

Rubber and polymer manufacturing plant

Moulds were located by memory and by walking the racks. A mould nobody could find held up a changeover, and there was no record of where anything had been put back.

ReactNode.jsMongoDBPLC integrationMQTT

What we built

  • Mould and rack masters, so every mould has one known, enforced location
  • Auto-run mode that sequences retrieval and executes it through the PLC
  • Live PLC communication built into the application rather than a separate SCADA licence
  • Alarm history with a full fault trail, and scheduled report generation
  • Role-based permissions and automated database backup

Production Planning & Shop-Floor System

Machine tools manufacturer — production division

Production was tracked in log books. By month-end nobody could reconstruct which station a delay had come from, or where a sub-assembly had gone.

ReactNode.jsMongoDBWindows ServerIIS

What we built

  • Assemblies, sub-assemblies, parts, spares, materials and projects
  • Stations, processes, process templates and routing
  • Shifts, operators, log book and idle-time capture
  • Stock ledger with internal and outward delivery challans and store movement
  • Live settings and software-version control across machines

Plant ERP Migration

Machine tools manufacturer

Buying, stock and dispatch ran on a legacy system tied to specific machines in the office, with no usable audit trail.

ReactNode.jsExpressMongoDB

What we built

  • Purchase orders, sales indents, internal indents and assembly indents
  • Item, group, supplier, customer, machine and model masters
  • Delivery challans, stock templates and a full report suite
  • Activity log recording who changed what, and when
  • Migration of the complete transaction history off the old system

Service & Job-Card Management

Machine manufacturer — service division

Breakdown calls, the spares issued against them, and the invoice that followed lived in three separate registers that were reconciled by hand.

ReactNode.jsMongoDB

What we built

  • Job cards with service logs, machine master and machine range
  • Order requests with approval logs, indents and purchase orders
  • Items delivered, pending items, delivery challans and inventory reports
  • Invoices, payments and structured customer feedback capture

Dynamic Tilt Test Station — PLC & HMI

Industrial test equipment manufacturer

An existing test station needed a control upgrade, including communication and velocity control that the original programme did not cover.

Siemens TIA PortalPLCHMI

What we built

  • Siemens TIA Portal PLC programme with operator HMI screens
  • Station upgrade adding communication and velocity control
  • Device configuration and commissioning support on site

Weighbridge Automation & IoT Gateway

Manufacturing group

Weights were read off the indicator and typed into a register — slow, and a recurring source of disputes with transporters.

Node.jsMongoDBAWS IoTMQTT

What we built

  • Direct weighbridge integration with automatic weight capture
  • Receipt generation and printing, with company and user management
  • Device telemetry published to AWS IoT over MQTT

02Water, Utilities & Public Infrastructure

Distributed assets across sites with thin networks and nobody on hand to check them.

AI Water Flow & Crowd Safety Monitoring

Infrastructure contractor — proposed to a state tourism department

Waterfall sites had to be assessed for visitor safety, but no flow meter can be installed in an open cascade, and headcount was estimated by eye.

NVIDIA JetsonEdge AIPTZ camerasReactLeaflet

What we built

  • Edge AI measuring water width against calibrated reference lines — no instrument in the water
  • Automatic headcount and crowd-density detection from the camera feed
  • Restricted-line intrusion detection raising an alert the moment it is crossed
  • Live map of all monitored sites, recoloured as each flow band changes
  • Officials' console: KPIs, live camera with AI overlays, PTZ presets, telemetry and device health
  • Public web and mobile app with visit planning, outlook, safety guidance and alerts

Multi-Company Water IoT Platform

Water technology company

The operator needed to onboard many client companies onto one platform, each seeing only its own devices, users and history.

Node.jsMongoDBReactMQTT

What we built

  • Device monitoring with live status and complete log history
  • Remote control of field devices from the web application
  • Notification and alert routing to the responsible staff
  • Separate operator console and client-facing app on a JWT-secured multi-tenant core

Pumping Station & Energy Monitoring

Water infrastructure operator — multiple sites

Motor failures surfaced as complaints about no water, and consumption was reconciled from meter readings taken by hand once a month.

Node.jsMongoDBReactMQTT

What we built

  • Station and device management with a live operations dashboard
  • Power meter integration with continuous consumption logging
  • Scheduled report generation and contact-log alerting
  • Two separately branded portals served from one backend

Borewell Security & Monitoring

GPS and security solutions company

Borewell installations sit unattended in the open. Tampering was discovered late, and there was no record of what had happened at the site.

Node.jsMongoDBReactMQTT over TLS

What we built

  • MQTT service with certificate-based device authentication
  • Device registration, master data, complaint workflow and device-level logs
  • Separate super-admin, company admin and end-user applications
  • Device simulator so the embedded team could test the full path without hardware

03Fleet, GPS & Field Operations

Vehicles, field staff, and remote assets that have to report in from wherever they are.

Employee Tracking & Attendance

GPS solutions company

Field attendance was self-reported over phone calls, and supervisors had no way to confirm a visit had actually happened.

React NativeExpoNode.jsMongoDBFirebase FCM

What we built

  • Android application built with React Native and shipped through EAS
  • Live employee location and attendance capture
  • Firebase push notifications to staff devices
  • Supervisor web dashboard over the same API

Field-Force Management Platform

In-house platform — deployed and customised per client

Companies running sales and service staff on the road need attendance, tasks, orders and expenses in one place, on a phone that works with intermittent signal.

ReactNode.jsMongoDBExpoReact Native

What we built

  • Thirteen modules across a tenant dashboard, a mobile app and an operator console
  • Live staff tracking on a map with background location on the device
  • Geo-verified attendance — punch-in permitted only at the correct location
  • Automatic conveyance distance calculation for travel reimbursement
  • Tasks, orders, expenses, custom forms and a detailed attendance muster

GPS Telematics Integration

Fleet tracking deployments

Off-the-shelf tracker platforms gave a map but not the reports the operator actually ran the business on.

Teltonika FMBNode.jsMQTT

What we built

  • Teltonika FMB-series configuration and remote SMS command setup
  • Custom decoding and telemetry ingestion into our own platform
  • Trip, route-history and driver reporting built to the operator's definitions

04Business Platforms & SaaS

Multi-tenant products where the operator sells the software to their own customers.

Clinic & Hospital Management SaaS

Healthcare software company

Clinics were running reception, treatment notes, pharmacy and accounts on separate tools, and the operator wanted to sell one subscription product covering all of it.

ReactNode.jsMongoDBChargebeeMQTT

What we built

  • Patients, appointments, doctors, prescription templates and treatment plans
  • Lab and lab-work management, medicine master and pharmacy billing
  • Full inventory: categories, items, stock in and out, suppliers and valuation

In-house platform — deployed and customised per client

Smaller businesses need GST-correct billing with real stock and receivables behind it, without the weight of a full ERP.

ReactNode.jsMongoDBJWT

What we built

  • Sales, purchase and all voucher types, with cancel-and-audit that preserves history
  • Stock management, party ledgers, receivables and outstanding reports
  • One date-range engine shared by every list and report, computed in local time
  • Multi-business tenancy with a super-admin application
  • Company logo, signature and seal applied to printed documents

Payroll & Salary Control

GPS and services company

Salary was calculated in spreadsheets, advances were tracked separately, and corrections left no trace.

ReactNode.jsMongoDB

What we built

  • Employee master, salary periods and period-wise entries
  • Advance management adjusted automatically against salary
  • Settings, dashboard and a complete audit log of every change

Dealer & Distribution Management

Battery distribution business

Dealer stock, pricing and outstanding were maintained per dealer in separate files, so network-wide position was never current.

ReactNode.jsMongoDB

What we built

  • Dealer master with dealer-wise ledger and outstanding position
  • Stock, product types and price list management
  • Product and warranty registrations with full transaction history
  • Distributor dashboard and reporting

05Connected Products & Embedded

Products where the firmware, the radio link, and the cloud ship as one system.

Connected Reaction-Training System

Sports and fitness technology company

A training product needed floor tiles and wearable pods driven in live patterns from the cloud — two different radio technologies, one PC, and no tolerance for a dropped frame mid-session.

ESP32-S3STM32CAN / TWAIESP-NOWOTANode.jsMQTTReact

What we built

  • ESP32-S3 gateway driving tiles over a CAN bus and pods over ESP-NOW on a single PC link

  • MQTT-to-CAN bridge on the station PC so the platform can drive the physical hardware
  • Backend for training patterns, pattern templates, sessions, players and assessments
  • Trainee and administrator applications, own MQTT broker, and a database snapshot module

Industrial IoT Product Line

Productised from repeated client requirements

Several requirements came back often enough to justify building them once properly rather than quoting them from scratch each time.

STM32ESP32ModbusLTEMQTT

What we built

  • IoT-enabled PLC boards with eight digital inputs and eight outputs
  • Drilling-rig telemetry converting drill-head RPM into auditable rod counts
  • Solar plant monitoring with string-level performance and fault alerting
  • Health and gaming kiosks combining LiDAR height measurement with BMI
  • GPS tracking and smart water management devices

06Ready to deploy

Some of it is already built.

These platforms exist and run today. Where one fits your operation, the work is configuration and the changes specific to how you work — not writing it from scratch. That is the difference between a delivery measured in weeks and one measured in quarters.
