Custom Android AOSP ROM Development (Advanced Isolation + Framework Customization)
I am looking for an experienced Android systems developer to build a custom Android ROM based on AOSP for a Realme C21Y (Unisoc/SPD platform).
This is not a standard Android app project. I need deep framework-level Android customization focused on:
* custom app isolation architecture
* framework-level service modification
* privacy-focused system design
* advanced multi-user environment behavior
* custom location/system service behavior
* telemetry reduction and system optimization
The ROM should prioritize:
* stability
* clean architecture
* performance
* modularity
* privacy-focused behavior
Main Requirements
Core ROM Features
* Build and maintain custom AOSP-based ROM
* Multi-user isolation enhancements
* Framework-level customization of Android system services
* Performance optimization for target hardware
* Stable rooted environment compatibility
Framework Modifications
Experience modifying:
* LocationManagerService
* PackageManagerService
* AppOps
* Sensor framework
* Binder IPC related services
* system_server behavior
Custom Features
* Custom app isolation behavior
* Selective package visibility filtering
* Per-app permission restriction logic
* Framework-level location virtualization concepts
* Background service stability improvements
* Optional custom settings/configuration panel
Root/Hooking Compatibility
Knowledge of:
* KernelSU/APatch
* Zygisk
* LSPosed/Xposed architecture
* Android runtime hooking concepts
Security / Privacy
Strong understanding of:
* Android security model
* SELinux policy
* Android multi-user architecture
* Privacy-focused Android design
* Telemetry reduction strategies
Preferred Skills
Developer should ideally have experience with:
* AOSP compilation
* Device trees/vendor blobs
* Custom ROM development
* Android internals
* Linux kernel basics
* SELinux
* Binder IPC
* Android framework engineering
* Performance optimization
* System-level debugging
Deliverables
* Bootable ROM image
* Source code/modification documentation
* Flashing instructions
* Recovery/rollback instructions
* Stable update path
* Documentation of framework modifications
Important
Please apply only if you have real experience with:
* AOSP/framework development
* custom ROM engineering
* Android system internals
This project requires systems-level Android knowledge, not standard Android app development.
Please provide:
* examples of previous ROM/framework work
* GitHub/GitLab if available
* experience with AOSP or custom Android systems
* devices/platforms previously supported
