Welcome — My Developer Journey

Hey, I'm Arun Aditya — welcome to my corner of the internet.

This is the first post on my portfolio blog, and I figured the best place to start is where every good story starts: the beginning.

College Days — Where It All Started (2016–2020)

I did my Bachelor of Technology in Computer Science, and honestly, the moment I sat in front of a computer and wrote my first program, something just clicked. There was something almost magical about the idea that you could tell a machine exactly what to do and it would do it — no questions asked.

During my four years I got my hands dirty with a bunch of different domains — data science, machine learning, web development, and Android app development. I was the kind of student who couldn't just study from textbooks; I had to build something with every new concept I learned.

Of all the things I explored, Android development hit differently. The reason was simple: I could write an app and immediately run it on my own phone. My phone. Something I carry in my pocket every day. That instant tangibility — being able to show people something real and working without them needing a laptop or a browser — was incredibly motivating. I was hooked.

First Job — Building Vitran at Aroma Enterprises (2020–2022)

After college I joined Aroma Enterprises India Ltd. and got thrown into the deep end right away — in the best possible way.

I worked on the company's flagship product: Vitran (short for Vitaran, which means "distribution" in Hindi). It was a suite of three interconnected Android applications built around a single core workflow — registering shops, selling products, and delivering them. Think of it as the digital backbone of a distribution network, all running on Android devices in the field.

Working on a product used by real people in real business operations taught me things no college course could. Tight deadlines, production bugs, user feedback that actually matters, performance on low-end devices — this was where I grew up as a developer.

After 2.6 years, I had a solid foundation in building production-grade Android apps. But I was ready for the next challenge.

Mercedes-Benz R&D India — Going Deeper into the Stack (2022–Present)

Joining Mercedes-Benz Research and Development India (MBRDI) — the largest R&D center for the Mercedes-Benz Group AG outside Germany — was a turning point.

Here I shifted from building consumer-facing apps to something much closer to the metal: in-car infotainment systems. I work on the platform and applications that power the in-car experience — things like joining a meeting from your car, checking your calendar, reading emails, and managing notes directly from the infotainment screen.

This is where I was properly introduced to the Android framework and AOSP. When you're building software that runs on a car's infotainment unit rather than a smartphone, you can't just depend on what the Play Store gives you. You need to understand how Android actually works underneath — the framework layer, system services, Binder IPC, init, SELinux. It fundamentally changed the way I think about Android.

That curiosity carried over into personal projects too. I started experimenting with AOSP builds on Raspberry Pi 5 — writing Linux kernel modules, building native system services, and exploring the parts of Android that most app developers never touch. A few of those projects are right here on this site.

Content Creation — Learning in Public

Parallel to all of this, I've been writing and sharing online since my college days.

Whenever I learn something new — a new API, a debugging trick, a deep dive into a framework — I write about it. It started with technical posts on Medium and LinkedIn, just as a way to cement my own understanding. But over time it became something I genuinely look forward to.

Two things keep me coming back to it:

It keeps me sharp. Writing forces you to understand something well enough to explain it to someone else. You can't fake it in a blog post.

The DMs. Every once in a while someone messages me saying a post helped them fix a bug they'd been stuck on for days, or that it helped them understand a concept they'd been struggling with. That feeling never gets old.

It's also how I've built some of my best professional connections — developers, engineers, and learners from all over the world who found value in something I shared.

My YouTube channel Silicon to System is the next chapter of that same instinct — taking the same ideas from blog posts and bringing them to life visually.

What This Blog Is About

This blog is where I document things I'm learning, building, and thinking about — mostly in the Android and systems programming space. You'll find:

Deep dives into Android framework internals and AOSP
Practical guides on Android development tools and patterns
Notes from building things with Linux kernel modules and Raspberry Pi
Occasional thoughts on engineering, careers, and learning

No fluff, no filler — just the stuff I genuinely find interesting and hope you will too.

Thanks for being here. Let's build something cool.
