The recurring problem

IoT projects rarely fail on hardware. They fail on process and operations: brittle firmware setups, late testing, unclear releases, and painful cloud migrations.

Late errors
  • Manual device testing becomes the bottleneck
  • Regressions are found too late
  • Releases become risky and expensive
Platform pain
  • Scaling and costs escalate
  • Unclear data model / retention
  • Missing observability
Pilot to fleet
  • OTA becomes mandatory
  • Security becomes non-negotiable
  • Multi-tenancy and role models

4 layers, one product

End-to-end thinking: engineering cycle + system integration. That’s how a prototype becomes a maintainable product.

Layer 1

Hardware & firmware (Rust) + engineering cycle

Rust firmware, CI/CD, reproducible builds, automated tests (unit/integration/HIL pragmatically), release/rollback strategy, traceability from requirements → tests → releases.

Layer 2

Data ingress

Provisioning, auth, telemetry & commands. Robust even with unreliable connectivity — with an observability baseline.

Layer 3

IoT platform

Custom (e.g. Postgres/TimescaleDB) or ThingsBoard integration/customization — aligned with use case, cost, and time-to-market.

Layer 4

Views & vertical solutions

Dashboards and production-ready customer views, roles/multi-tenancy, alerts/reports, and integrations into existing processes.

Service packages

Start here

Package 1: Rapid IoT Prototype (in days)

After the first call, we deliver a demo-ready slice (device → ingress → platform → view) that becomes the foundation for delivery.

Option

Package 2: Firmware engineering & security review

CI/CD, test strategy, security baseline, OTA process, and docs/traceability — hands-on and pragmatic.

Option

Package 3: End-to-End delivery (project)

From prototype to production-grade operation: observability, OTA, scaling/cost, and integrations.

Typical starting points

Legacy firmware, new product goals

Unstable builds, manual hardware testing, fragile releases, unclear ownership.

Cloud migration & platform pain

The platform doesn’t scale, costs too much, or is hard to operate.

Pilot to fleet

OTA, security, observability, data modeling, and multi-tenancy become critical.

Experience from industrial IoT work

Experience from an anonymized customer project (ASPION context): focus on maintainable engineering processes and production-grade system integration — not a one-off demo.
