Frequently Asked Questions
What services does Mohammed Rayyan offer?
Mohammed Rayyan offers three core engineering solutions: custom AOSP ROM and kernel development, end-to-end full-stack Next.js web application engineering, and premium UI/UX design systems with fluid GSAP motion.
What is the typical turnaround time for an engineering engagement?
Architectural audits take 3–5 business days, custom kernel and AOSP optimization sprints span 2–4 weeks, and comprehensive full-stack product builds typically require 4–8 weeks.
Do you support custom Android ROM and kernel optimization for specific devices?
Yes. We specialize in custom defconfig tuning, EAS scheduler adjustments, Clang compilation, and thermal throttling mitigation across modern Snapdragon, MediaTek, and Tensor platforms.
How does Ninety5 Studio guarantee project delivery and code quality?
All engagements follow milestone-based deliverable checkpoints with physical hardware benchmarking, automated linting, 100% type safety, and direct client review before sign-off.
Can you work with existing engineering teams and codebases?
Absolutely. We seamlessly integrate with in-house teams, providing specialized systems expertise, clean Git PRs, and detailed architecture decision records (ADRs).
