A deep dive into how ad injection works in short-form video feeds - covering timing heuristics, frequency capping, impression recovery, and the engineering trade-offs behind monetization at scale.

The journey from product feature to monetization lever is rarely straightforward. Here's how ad delivery decisions actually get made on mobile - the stakeholders, the trade-offs, and the engineering reality behind every ad you see in a feed.

Ad formats look simple from the outside. A banner, a video, a carousel. But behind each one is a mountain of engineering complexity that touches rendering, performance, measurement, and user experience all at once.

You can't fix what you can't see. Observability isn't just dashboards and alerts. It's a mindset that changes how you build, debug, and operate software.

Scale isn't just bigger numbers. It fundamentally changes how you think about code, releases, testing, and the relationship between your decisions and their consequences.

How I manage growing complexity in Android apps without falling into the trap of building abstractions nobody asked for.

Tech debt isn't inherently bad. It's a tool. The problem is when teams accumulate it unconsciously, without tracking it or paying it down strategically.

Speed and quality aren't always at odds. But when they are, knowing which one to optimize for is one of the most important judgment calls an engineer can make.

Five architecture mistakes I see repeatedly in Android codebases and the practical patterns I use to avoid them.

Optimization without measurement is guessing. And in my experience, engineers guess wrong about what's slow more often than they guess right.

Practical architecture patterns for Jetpack Compose that work in real production apps - not just sample projects.

Benchmarks measure what you tell them to measure. The performance problems that hurt users most are the ones that only appear in the real world, on real devices, with real usage patterns.

Code that works today but can't be changed tomorrow is tech debt waiting to happen. Here are the principles I follow to write Android code that lasts.

Code review isn't about catching typos. It's about protecting the codebase from subtle problems that compound over time. Here's what I actually focus on.

Compose is the future. Views are the present. When you're working in a codebase with years of XML layouts, the migration question gets complicated fast.

System design isn't just for backend engineers. Here's how I think about architecture, trade-offs, and scalability from the mobile side.

After years of building Android apps at different scales, here's how I think about architecture. Not the textbook version, but the practical one that survives contact with real products and real teams.

Most engineers design for the happy path first. I've learned to flip that around. Starting with how things break leads to better systems, fewer surprises, and code that holds up under real-world conditions.

The most impactful thing I do as an engineer isn't writing code. It's asking the right questions before I start. Here's my checklist.
