Decoupling Async State from UI Lifecycles

A lot of frontend bugs do not start from bad code. They start from a small semantic mistake: Treating Derived State as if it were real State. Full article is here👇

When Render No Longer Owns the Entire Data Flow

From Signals to Ownership: Why I Built a Dataflow Kernel

New article published: Building Reactive DevTools A reactive system should not be a black box. In this article, I explore how to make a signal-based runtime observable through node inspection, graph visualization, render counters, and hotspot tracking.

How React-Style Time-Slicing Keeps UIs Responsive

In my latest signal article, I explore how priority queues and layered execution can help a scheduler preserve interaction responsiveness while still maximizing performance utilization.

Building a Smarter Scheduler: Priority Queues and Layered Execution

I published a new article in my Signals series. This one is about the hidden cost of fine-grained reactivity: dangling nodes, stale edges, disposal, auto-unlinking, equality strategies, and why the dependency graph is just as important as the Scheduler.

Signal Internals: Managing Memory and the Dependency Graph

A Scheduler is the hidden commander of a reactivity system. It decides not whether something should run, but when it should run. New article: Building a Signal Scheduler

Building a Signal Scheduler: Sync, Batch, Priority, and Lazy Execution

New article in my signal-kernel series: Async Transactions for Signals How do you batch updates across await boundaries without breaking lazy computed or your scheduler model? This article shows the implementation and the trade-offs.
