Our Approach We work directly with AOSP source, custom kernels, HALs, and device trees to tailor ROMs for specific hardware. Our process covers de-Googling, SELinux and security tweaks, sensor integration, build optimization, QA, and OTA pipelines to ensure stable, update-ready deployments. Clarification Board 1. Which target devices/SOCs are in scope for the first build? 2. Do you already have vendor blobs and device trees, or should we prepare them? Text to Best Solution – Afeska

This is the kind of work that needs someone who has lived inside AOSP, not someone learning it on your repo. I can take your target hardware and deliver a clean, stable ROM that’s purpose-built for an in-car interactive display, with the right balance of performance, security, and maintainability. Set up the full AOSP build pipeline for your specific device target, including device trees, vendor blobs, and kernel alignment Remove Google services completely and replace dependencies with an OEM-safe, offline-capable baseline Apply security-focused hardening: reduced attack surface, tightened permissions, verified boot considerations, and controlled system apps Integrate sensor and automotive display requirements properly at framework and HAL level where needed Implement OTA update support with a reliable signing and rollout process Deliver reproducible builds, documentation, and a clear handover so future updates don’t become fragile I’ve worked on ROM-level customization where stability matters more than experimentation, and I’m comfortable owning the full path from source modification through flashing, testing, and update strategy.
