Bespoke IoT delivery

Bespoke IoT solutions start with real-world constraints, not templates. We operate as IoT solutions architects: you bring the problem, environment, and risk, and we design and build the complete system required to solve it, even under challenging conditions where off-the-shelf products fail.

Squared Technologies delivers full-stack IoT from first principles. That includes RF engineering, sensing strategy, custom hardware, embedded firmware, gateways, secure uplink, cloud platform, APIs, and the operational interface. Every layer is engineered to work together, because reliability, security, and maintainability are system properties.

RF and low-power estates are unforgiving. Interference, multipath, attenuation, duty-cycle limits, and battery budgets define what is possible. We engineer link budgets, field test plans, and deployment assumptions early so performance is predictable, not optimistic. The goal is repeatable operation across the estate, not a demo that collapses at rollout.

Hardware is designed for the environment and the lifecycle. We build custom electronics where needed, focusing on power, ruggedisation, test strategy, and clear compliance pathways. Firmware is treated as a long-life operational dependency: buffering, retries, OTA updates, deterministic behaviour under failure, and a provisioning path that scales across fleets.

Security is engineered as the boundary. We implement device identity and controlled onboarding, then enforce least-privilege access throughout the system. Transport and delivery surfaces are designed for zero trust operation: scoped permissions, auditable actions, and predictable failure modes that do not create unsafe bypass paths under pressure.

The platform layer turns telemetry into operational outcomes. We build ingestion, processing, storage, and customer delivery with traceable event trails and governed contracts. For enterprise-grade deployments we commonly implement on AWS using patterns that support scale and assurance. For smaller or dedicated deployments we can deliver a lean sovereign stack using Postgres as relational truth and object storage for evidence and history. The footprint changes, the discipline does not.

Where the problem demands it, we integrate analytics and predictive maintenance into the delivery: anomaly detection, drift monitoring, health scoring, and workflows that trigger action. The system is built so decisions are explainable and tied back to provenance, not opaque guesses.

The result is a bespoke IoT solution you can deploy at scale: engineered end to end, secured by design, validated in the field, and delivered as an operational platform your teams can run for years. That is what solutions-architected delivery looks like in practice.
