How We Onboard Your IoT App Developer
Most engagements move from initial requirements to active development within 3 to 5 business days, with no extended discovery phases and no lengthy onboarding cycles before anything gets built.
Share Your Requirements
Tell us your device types, connectivity protocols, cloud platform, and project stage, and we'll scope the right developer fit from there.
Developer Matching
We match an IoT developer to your device stack, backend language, product type, and working time zone.
Trial & Alignment
Evaluate code quality and communication on a real task, such as a device pairing flow or a live data dashboard, before committing to a longer engagement. Full-time hires include a free trial period.
Active Development
Your developer joins your sprint, gets access to your repos, cloud environment, and test devices or simulators, and contributes to production IoT work from day one.
IoT Applications Built for Real Businesses
Remote Device Management Platform for Industrial Meters and PLCs
Selec Controls needed to configure and manage meters and PLCs without sending engineers on-site. We built a cloud-based IoT platform that connects these devices and handles configuration and management remotely.
Work Delivered:
- Cloud-based IoT device management platform
- Remote configuration replacing on-site visits
- Device-to-cloud connectivity across meters and PLCs
For products where users pair, control, and monitor devices from a phone, with Bluetooth connectivity, push alerts, and live device status across Android and iOS.
Best for gateways and API-driven IoT workloads, including device-event handling, efficient communication layers, and real-time dashboards for connected systems.
Suitable for automation, analytics, and edge workflows, including data processing pipelines and backend layers that keep your IoT network organised.
For device firmware and microcontroller work, from reliable sensor logic and device communication to memory-safe, high-performance code on edge hardware.
A strong fit for enterprise IoT platforms that connect many devices, handle structured data flows, and integrate cleanly with your cloud environment.
Built for large data streams and concurrent workloads, with backend services that manage device messaging and keep data flowing under constant load.
Device-to-Cloud Ownership, Not Just the App Screen
Our IoT developers work across the whole chain, from device pairing and data ingestion to cloud APIs and live dashboards. You don't need separate vendors for the app and the backend, and nobody can say the problem sits on the other side of the handoff. One team owns how data moves from the device to your user.
Built for Real Devices and Unreliable Networks
IoT apps fail in the field, not in the demo. Our developers plan for dropped connections, offline devices, delayed data, and security from the first sprint, rather than patching them in after launch. That means apps that keep working when a sensor goes quiet or a user walks out of signal range.
Remote or Hybrid Delivery With Full Visibility
Your developers work remotely or in a hybrid setup, aligned to your time zone and release schedule. You get daily updates, weekly progress calls, and periodic senior-developer walkthroughs, so you always know the current state of your IoT project.

Industries Covered
Mobile apps for pairing, controlling, and monitoring devices over Bluetooth Low Energy or Wi-Fi, with live status and push alerts, built natively or in a cross-platform framework.
Connect multiple devices and sensors to a single platform with device authentication and centralised control, so teams get one clear view across their connected hardware.
Web and mobile dashboards that show live device data and let teams act on it from anywhere, built for manufacturing, agriculture, and logistics operations.
MQTT-based messaging and data ingestion using high-throughput backend services in Go or Node.js, so readings from thousands of devices arrive in order and on time.
Device-to-cloud connectivity on AWS or your preferred platform, with cloud security practices applied to device data, access control, and storage from the start.
Sensor-data models that flag likely equipment failures early and feed maintenance schedules and alerts, cutting downtime and unplanned repair costs.
Analysis of real-time and historical device data to uncover trends, track performance, and support planning decisions across your connected products.
Rules and triggers for threshold breaches and workflow automation, sending notifications the moment a reading changes so teams can respond faster.
Monitor and optimise energy use across devices and sites, with usage views that help reduce utility costs and support sustainability goals.
Need an IoT Developer Fully Committed to Your Product?
A dedicated IoT engineer works exclusively on your device app and connected platform, fully embedded in your sprints, your tools, and your release cycles with no split attention.
Full Product Ownership
A dedicated IoT developer owns your app and its device integrations every sprint and every release, without splitting attention across other client projects.
Sprint Integration
Your developer joins daily standups and backlog grooming and ships within your existing delivery rhythm, with no separate process or project layer to manage.
Device & Firmware Continuity
The same developer stays aligned with your device protocols, firmware versions, and app compatibility requirements across every release, so updates don't break devices already in the field.
Release Management
App store releases, device update rollouts, and automated build and release pipelines are handled directly, not delegated back to your internal team.
Industries We Build IoT Products For
Our IoT app engineers have built for sectors where connected devices, live data, and reliable remote control decide how well operations run.

Built for Every Stage of Your IoT Product
The right IoT development engagement looks different depending on where your product and team currently stand. Here is how we work across every stage.
Startups
Take your connected product from prototype to launch without the overhead of a full in-house team. Get a working device app, cloud connectivity, and an architecture that holds up as your device count grows.
Mid-Size Businesses
Scale your IoT product without losing reliability. Add dedicated engineers to your existing team, extend support to more device models and platforms, and keep firmware, app, and cloud versions in step as your fleet grows.
Enterprise Level Businesses
Standardise IoT architecture across business units and sites with shared device-connectivity libraries, unified build and release pipelines, and consistent security and monitoring coverage across your entire connected device fleet.
