I am rolling out an in-dash Android interactive display and need a seasoned AOSP specialist to turn the stock source into a lean, security-hardened custom ROM. The target hardware is a car-grade unit that hosts a camera alongside proximity and accelerometer sensors, so the build must include the right HALs and permissions for those components. What I want you to handle: • Fork the AOSP branch that best matches our SoC, import or craft the correct device tree and board-config, and fine-tune the kernel where necessary. • Strip every Google Mobile Service while preserving base Android stability. • Apply low-level security tweaks (SELinux policy work, verified boot, hardening flags). • Set up seamless OTA delivery (delta or full images) so field upgrades stay painless. • Run stability and regression tests on real hardware until the system is production-ready. Success for me means a reproducible build environment (preferably repo-based), flashable images that boot cleanly, all sensors and the camera functioning, and OTA packages that install without issue. If you have shipped custom ROMs before and can show commits or images that prove it, we should talk

Hello! Building a lean, hardened AOSP ROM for in-dash automotive hardware is exactly the kind of low-level Android work I specialise in. Your requirements custom device bring-up, sensor/camera support, GMS removal, and production-grade OTA—fit a clean, reproducible AOSP workflow. How I’d approach this AOSP & Device Bring-Up • Fork the correct AOSP branch aligned to your SoC • Import / build device tree, board config, and vendor blobs • Kernel tuning for camera, proximity, accelerometer HALs De-Googled & Stable Base • Full removal of GMS and Google dependencies • Preserve CTS-safe core Android services and stability Security Hardening • SELinux policy tightening (enforcing, least-privilege) • Verified Boot / AVB configuration • Kernel and build-time hardening flags OTA & Deployment • Repo-based reproducible build environment • Full or delta OTA pipeline (A/B if supported) • Signed images and rollback-safe updates Validation • Boot, sensor, and camera testing on real hardware • Regression and stress testing before release I’ve shipped custom AOSP ROMs for embedded and automotive-adjacent devices and can share commit history and images on request. Let’s start by reviewing your SoC, kernel version, and sensor stack. Best regards, Jasmin
