What I write about

The six themes I keep coming back to.

LLD

Low-level design — object modeling, design patterns, and writing code that survives the second pull request.

How to build systems that scale: capacity, consistency, caching, queues, and the trade-offs nobody puts on the whiteboard.

JVM internals, concurrency, memory, performance — the things that show up in production at 3 AM.

LLMs, prompts, retrieval, evals — turning a fuzzy model into something you can actually ship.

Tool-using agents, planning loops, and what breaks when you let a model take actions on your behalf.

The architecture, infrastructure, and engineering practices for building agentic systems that don't collapse under their own weight.
