Full‑Stack
React, Next.js, Prisma, Postgres. Modern frontend meets pragmatic backend—with type safety everywhere.
Low‑Level
Android kernels, custom ROMs, HAL drivers, device trees. When the problem lives below the OS, that's where I thrive.
Design
Interfaces that feel alive. Micro-interactions, spatial composition, and attention to every pixel.
C:\Users\Pepsy\Stack
PRODUCTION_READYHooks, composition patterns, and performance-first thinking. The core of every UI I build.
App Router, Server Components, edge rendering. The best way to ship React to production.
Types catch bugs before users do. Safer APIs, fearless refactoring, better DX.
Utility-first CSS that scales. Design tokens, responsive, dark mode—all handled.
Schema-first ORM with typed queries. Migrations, relations, and DX that actually works.
Rock-solid relational database. JSONB, full-text search, indexes, and serious performance.
Auth, storage, realtime, and managed Postgres. For when you need to move fast without cutting corners.
Consistent environments from dev to production. Container-first, always.

Not just apps—I work at the deepest layers. Custom kernels, device drivers, HAL implementations, and ROM builds. When the problem is below the operating system, that's where things get interesting.
Kernel & Drivers
Patching schedulers, undervolting, fixing memory leaks at ring 0. Pure C and Assembly manipulation.
- ■ Scheduler
- ■ Power
- ■ Performance
ROM & Device Tree
Bringing up hardware, fixing SELinux policies, composing vendor trees for AOSP.
- ■ AOSP
- ■ Device Tree
- ■ HAL
Apps & SDK
Bridging low-level APIs with high-level Kotin/Java SDKs for seamless user experiences.
- ■ Kotlin
- ■ Flutter
- ■ Jetpack
