Android Engineering
Android apps with Kotlin and Jetpack Compose. MVVM and Clean Architecture underneath, Room and Retrofit for data. I can take an app from a first commit to the Play Store.

I'm a software engineer in Kathmandu, Nepal. I started coding in 2019 and have spent the years since building Android apps, backend systems, and open-source tools for Unity internals: IL2CPP instrumentation, Frida scripts, ADB automation. Right now I'm learning Rust and figuring out what comes next.

// about
Engineer, tinkerer, writer.
I started coding in 2019. I was stuck in my village during the corona lockdown with a lot of free time, and I was already studying computer science in 11th class, so I put the two together.
After 12th I did a BSc.CSIT from a TU-affiliated college in Nepal. Class gave me the theory. My GitHub gave me the practice: I spent those years taking Android apps and Unity games apart to see how they worked, then building my own tools, from ADB automation scripts to a DEX-to-C++ protection suite.
My bachelor's is complete now. I'm taking some free time and looking at what's out there. Right now that means learning Rust.
I work mostly in IDA Pro, Frida, and Jetpack Compose, and I try to write code that reads cleanly. I reverse engineer to learn. Every reversing project here exists for learning and research.
Currently
- Learning Rust
- Studying cloud architecture
- Writing on the blog
// what i do
What I work on
Four areas I keep coming back to.
Reverse Engineering & Tooling
I take software apart to learn how it works: IL2CPP dumps, Frida hooks, long sessions in IDA Pro. Dex2C goes the other way. It turns DEX bytecode into C++ so the logic is harder to pull apart.
AI & Developer Tools
Musker, a chatbot running on Cloudflare Workers AI. An adapter that takes Anthropic API calls and forwards them to OpenAI-compatible backends. A TypeScript client for Sora video generation.
Edge & Cloud Infrastructure
CloudEdge, a blog platform that runs entirely on Cloudflare edge infrastructure. A self-hosted YouTube analytics service. Docker containers on AWS and GCP.

Dex2C: a protection suite
I spend a lot of time taking software apart, so I built something that makes it harder. Dex2C turns Android DEX bytecode into native C++, so the app logic is no longer sitting in plain bytecode. One idea, four repos: the core engine, a web dashboard, backend services, and an Android client.
// projects
Featured work
Open source, in one place. The big ones first, then the small experiments.
ImGui overlay integration for Unity games. Hooks the render pipeline to expose in-game debug interfaces.
Extracts metadata from Unity IL2CPP builds, fast.
Backend services for the Dex2C DEX-to-C++ protection suite.
Android client for the Dex2C protection suite.
Dumps IL2CPP metadata from live processes using Frida. Analyze stripped Unity binaries without a symbol table.
Reference source for libmain.so in Unity games. Base for understanding the native Unity bootstrap layer.
IL2CPP runtime interaction from native C++ on Android.
Web dashboard for the Dex2C protection suite.
