Expertise Proof
These articles show how Combotto reasons from field evidence to audit scope, findings, backlog, and follow-through. The library is listed newest first so recent proof and shipping work stay easiest to find.

A working note on turning a Rust IoT gateway into an auditable system: preserving telemetry history, making certificate posture visible, and using AI-assisted review to turn runtime evidence into findings a team can act on.

Notes from designing a functional prototype enclosure for the STM32 `B-L475E-IOT01A2` before field testing: which board details mattered, how documentation and real measurements shaped the print, and why service access, transport, and fast reprints mattered more than visual polish.

A planning note for the next Combotto field demo: two B-L475E-IOT01A2 devices with SPSGRF-868 radios transmitting over 868 MHz, one receiver bridged by serial into a Raspberry Pi 5, and a longer-range telemetry path than Wi-Fi alone usually gives inside and around buildings.

Captured field proof of a Rust IoT gateway on Raspberry Pi 5 handling three STM32 devices over MQTT/TLS, WAL backlog during broker outage, and clean recovery after broker return. Useful for teams evaluating IoT gateway reliability before rollout.

The Combotto Audit Engine is now ready for pilot projects: canonical reports, run-to-run delta tracking, and alerts for regressions and expiring certificates—built to make Audit → Sprint → Retainer delivery faster and more verifiable.

What breaks when an edge IoT gateway runs 24/7? Real operational lessons from running a secure edge-to-cloud system under intermittent connectivity, focusing on reliability, observability, and silent failure modes.

Edge-to-cloud systems without proper observability suffer from slow debugging and reactive incident response. Learn why logs alone fall short and how observability reduces risk.

I created a structured IoT Architecture Audit Checklist. It captures the core principles of reliability, security, and observability, and provides a consistent process for evaluating device -> gateway -> cloud pipelines.
Next Step
Share the architecture slice, the current risk or delivery pressure, and the decision window. Combotto replies with a fit check, a suggested audit scope, and the clearest next step.
