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.

After years of writing code that directly impacts revenue at massive scale, these are the hard-won lessons about what actually matters when your diff can move millions of dollars.

Lessons from running monetization experiments on products with hundreds of millions of users - how to think about risk, rollback strategies, and the hidden costs of moving too fast or too slow.

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.

Shipping to 100% on day one is a gamble. Gradual rollouts turn a gamble into a calculated risk with early warning systems built in.

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.

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 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.

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.

Joining a new team means inheriting a codebase you didn't build. Here's the system I use to get productive fast without pretending to understand things I don't.

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.
