ANDROID & FULL STACK DEVELOPER BUILDING FROM KERNEL TO CLOUD.

I build and maintain custom Android experiences, from compiling ROMs and maintaining device trees to tuning kernels and optimizing performance for real world usage. Working heavily in Linux environments, I use tools like Git, ADB, logcat, and automated CI/CD workflows to debug, develop, and ship stable builds with attention to both performance and usability.

Alongside Android development, I create modern full stack web applications with clean UI, responsive design, and scalable backend systems using Node.js and modern web technologies. I enjoy working across every layer of development, from low level Android internals to polished frontend experiences and production ready deployments.

Experience

Active — Ongoing

Independent Developer & Open Source Maintainer

Full-time across Android ROM maintenance (8 devices), device tree bringups, kernel tuning, and backend services. Shipping weekly builds via CI/CD pipeline, engaging with the community on Telegram and GitHub discussions.

Ongoing

Backend & Full Stack Engineering

Designing REST APIs, realtime WebSocket systems, authentication services, and admin dashboards. Building production Node.js backends with PostgreSQL and Redis caching.

Foundation

Android Internals & Linux Systems

Started with custom recovery flashing, evolved into compiling AOSP from source, configuring kernels, and understanding the full Android boot chain from bootloader to SystemUI.
