I am a hardware firmware engineer with over a decade of experience designing embedded systems for industrial automation. Since 2022, my sole professional focus has been Decentralized Physical Infrastructure Networks (DePIN). I design the cryptographic handshakes that allow physical machines to earn cryptocurrency by validating real-world telemetry. My laboratory in Tokyo builds custom secure bootloaders for ESP32 microcontrollers and Raspberry Pi compute modules. I solve the hardest physical problem in Web3: proving to a smart contract that a remote hardware sensor is actually generating physical power or routing real wireless packets, rather than running a spoofed software simulation. Because physical network deployments require continuous multidisciplinary coordination, I operate actively on both sides of this marketplace. I offer specialized embedded firmware development while consistently posting high-value contracts seeking core Solidity developers to write the on-chain reward distribution contracts that sync with my hardware.
