Your profile

• Deep Python: 5+ years of writing production Python other people depend on. Async, typing, packaging, testing. You've designed APIs that other engineers built on, not just glue code.
• You've debugged a real protocol against real hardware: gRPC, serial, TCP, OPC UA, CAN, USB. Which one matters less than having sat with a packet capture and a device that won't respond.
• You ship without a spec: When the documentation is wrong, you reverse-engineer, instead of filing a vendor ticket and waiting. 
• You build for other developers: An SDK, a library, an internal platform. Something where your job was making other engineers faster.
