The challenge

Where teams get stuck

The problems we're most often brought in to solve.

  1. 01

    Data is lost when devices disconnect

    Field devices drop readings whenever connectivity fails, leaving gaps in the data that operations and reporting rely on.

  2. 02

    No real-time view of fleet health

    Device status is known only through periodic manual checks, so faults surface late and site visits are poorly targeted.

  3. 03

    Pilot pipelines do not scale

    An architecture that worked for a handful of devices struggles with message volume, security and provisioning as the fleet grows.

Overview

IoT & Connected Systems at VulcanTech

IoT development is the engineering of the pipeline that carries data from connected devices to the cloud and turns it into operational insight. VulcanTech builds device telemetry, MQTT ingestion, time-series storage and real-time dashboards for connected fleets. Offline buffering is standard scope, so intermittent connectivity does not mean lost data. The outcome is a fleet operations teams can monitor in real time, replacing periodic manual checks in the field.

Key deliverables

  • Device telemetry pipeline over MQTT or HTTP
  • Offline buffering and synchronisation
  • Real-time fleet monitoring dashboard
  • Alerting rules and notifications
  • Device provisioning process

What you get

What IoT & Connected Systems includes

  • Telemetry pipeline

    Device data delivered over MQTT or HTTP into cloud ingestion, with message validation and structured storage.

  • Offline buffering and sync

    Devices retain readings locally during outages and synchronise automatically once connectivity returns.

  • Real-time fleet dashboards

    Live views of device status, readings and alerts for operations teams.

  • Time-series storage

    Storage designed for high-volume sensor data, with retention policies and efficient historical queries.

  • Device security

    Per-device credentials, encrypted transport and controlled provisioning for devices joining the fleet.

  • Thresholds and alerting

    Configurable alerts when readings cross thresholds or devices stop reporting.

Our process

How we deliver

A delivery process you can see into — from first workshop to production support.

Book a free consultation
  1. 01

    Discovery

    A focused working session on your objectives, constraints and existing systems. It concludes with a scoped proposal and a clear view of value, risk and effort.

  2. 02

    Architecture & planning

    We agree the target architecture, data model and integration approach before product code is written, and secure your sign-off.

  3. 03

    Iterative delivery

    Working software reaches a staging environment on a regular cadence, giving stakeholders continuous visibility and the ability to steer priorities.

  4. 04

    Assurance & hardening

    Automated testing, accessibility and performance budgets, and a security review are completed before anything reaches production.

  5. 05

    Launch & continuity

    We manage cutover and remain engaged through an agreed support period, with a structured handover to your teams or ongoing operation by ours.

Engagement models

Work with us the way that suits you

Explore engagement models →

  • Outcome-based delivery

    A defined scope, timeline and commercial model agreed after discovery. We own delivery risk against the agreed outcomes.

    Best for: Well-defined initiatives, MVPs and first releases

  • Dedicated product teams

    A cross-functional pod — engineering, design, QA and delivery leadership — aligned to your roadmap and scaled as priorities change.

    Best for: Long-term product development and evolving roadmaps

  • Team extension

    Senior engineers embed in your organisation, work inside your processes and report to your leaders — on contracts that assign all IP to you.

    Best for: Adding specialist capability without growing headcount

Tools & technologies

The stack we build with

  • MQTT
  • AWS IoT Core
  • InfluxDB
  • Grafana
  • Python
  • Node.js

Why VulcanTech

A partner, not a vendor

Senior engineering, honest delivery, and work we can name.

  • Senior engineers own delivery

    The engineers who scope your programme in discovery are the engineers who deliver it. There is no hand-off to a junior bench after contract signature.

  • Engagement models that fit

    Outcome-based delivery, dedicated product teams, team extension or global capability centres, matched to how your organisation prefers to work.

  • A verifiable track record

    Every customer story we publish describes real production work, naming the client wherever confidentiality allows, including public-sector platforms secured through competitive tenders.

  • 80+ projects in 16 countries

    Delivered since 2021 across the public sector, real estate, healthcare, manufacturing and consumer technology, for regulated and high-growth organisations alike.

FAQ

Frequently asked questions

Can't find what you need? Ask us in the discovery session.

Devices buffer readings locally and synchronise once connectivity returns. This is standard scope rather than an afterthought, because intermittent connectivity is the norm for most field fleets. We size local storage to your expected outage durations and ensure synchronised data arrives in the correct order without duplicates.
