Industrial Linux daemons, edge gateways, and QNX Neutrino user-space for plant floors, fleets, and custom boards.
When downtime costs money → harden
Daemons, protocol bridges, and watchdogged services tested on real racks and boards — with docs your maintenance crew can follow at 2 a.m.
Linux · QNX · MQTT · Modbus · OPC-UA · OTA
Discovery · site survey
Hardware, protocols, latency budgets, and safety boundaries documented before code hits the plant floor.
Build · bench tests
C/C++/Python services that move Modbus, MQTT, OPC-UA, or serial into SQL, cloud, or SCADA historians.
Harden · soak testing
systemd units, watchdogs, secure boot paths, and failure modes that fail safe — not silent.
Fleet · long-term support
Staged deploys, rollback images, and runbooks so every gateway in the fleet stays on a known build.
4 phases · from bench to fleet
Software for environments where downtime costs money. We write C/C++/Python services, protocol bridges, watchdogged units, and OTA hooks — bench-tested on your hardware before fleet rollout. Documentation is written for the technician on call, not just our build machine.
When the product lives in a rack, a vehicle, or on a plant floor, reliability beats UI trends. Swift Media builds Linux daemons, edge gateways, and QNX Neutrino applications tested on target hardware with fleet update hooks.
Protocol translation, local buffering, store-and-forward when uplink fails.
Historian export, alarm forwarding, and operator tools without replacing controls.
Health telemetry, remote config, and controlled OTA updates.
IPC with real-time tasks, resource managers, and safety-partition awareness.
| Linux targets | Debian, Ubuntu, Yocto custom images, vendor BSPs |
|---|---|
| QNX | Neutrino 7.x user-space, pthreads, message passing, io-pkt networking |
| Languages | C, C++, Python, Bash — chosen per latency and team skill |
| Protocols | Modbus RTU/TCP, MQTT, OPC-UA, CAN, serial ASCII, proprietary framing |
| Process model | systemd units, watchdog timers, graceful shutdown, structured logging |
| Updates | Signed packages, A/B partitions, or vendor OTA hooks with rollback |
Constraints first
CPU, memory, network, safety partition, and certification boundaries.
On-target early
No “works on my laptop” — CI builds for the actual architecture.
Production hardening
Observability, remote support hooks, and update policy before scale-out.
