- OTA update pipelines
- Ultra-low-power design
// WEEDMARK SYSTEMS CORP. — INDUSTRIAL SOFTWARE & HARDWARE CONSULTING
Industrial IoT consulting: from bare-metal firmware to cloud-scale telemetry. We design, build, and harden systems that operate where failure is not an option.

End-to-end topology from sensor to cloud: fleet provisioning, device identity, telemetry pipelines, digital twins.
Companion apps for connected devices — video doorbells, smart thermostats, smart locks. From first pairing to daily glanceability.
Orchestration at the edge, brokers that don't drop messages, and infrastructure as code from factory to field.
Brownfield is our home field. Gateways and translators that make 30-year-old PLCs speak modern protocols.
Threat modeling, secure boot, and PKI done right. Security audits aligned with industrial standards.

We map your physical and digital terrain: existing equipment, constraints, failure modes, and the outcome that actually matters.
──▶ NEXTA working system in weeks, not quarters. Real hardware, real radios, real data — not slideware.
──▶ NEXTEnvironmental testing, security audit, regulatory prep. The unglamorous work that separates demos from deployments.
──▶ NEXTRollout, monitoring, OTA infrastructure, and a maintenance plan. We stay on call so you don't have to.
