LoRaWAN estate recovery

The council's housing LoRaWAN gateway estate was effectively owned by the incumbent supplier. I led the technical recovery — regaining control of the hardware, the network keys and the management plane — in time for a re-tender that materially improved the commercial position.

Solution Architect / IoT Tech Lead — technical lead for recovery and re-tender.

Vendor lock-in on critical infrastructure. Re-tender was approaching with no credible plan to switch supplier without ripping out physical gateways across the estate.

1. 01 Mapped the estate, access methods and dependencies; separated what was contractually ours from what was practically the supplier's.
2. 02 Designed a transition path that kept services live during handover.
3. 03 Supported procurement and contract negotiations with the technical evidence needed to shift commercial terms.

• ▹ £200k+ saved against the pre-recovery commercial position ahead of re-tender.
• ▹ Estate returned to council control; vendor competition restored for the re-tender.
