Your ESP32 isn't "randomly" crashing. Here is the real reason.
I see the same post on forums every week: "My ESP32 works fine on my desk, but it crashes when I add Wi-Fi or sensors."
The developer assumes it's a hardware fault. They replace the board. It crashes again.
The real problem is almost never the hardware. It is a race condition in the task scheduling or a stack overflow that only triggers under load.
When I build firmware, I don't just write code that works in a lab. I build systems that survive the field. The flaw is usually in how the tasks are prioritized, or in the memory allocation that isn't handled when the network stack spikes.
If your device is failing in the field and you cannot find the root cause, that is the exact problem I solve. I read the code, I find the flaw, and I ship a fix.
If you are stuck on an embedded issue, my inbox is open. Tell me the symptom, and I will tell you if it is fixable.
