Design Before Code: A Discipline for AI-Assisted Engineering
When AI writes the code, the reasoning that produced it never exists anywhere except in a transient context window. A two-session pattern — a long Workshop to build the design, and a series of fresh Cold Reads to test it — moves accountability back where it belongs.
A Traffic-Aware BFF for Next.js: RSC Strategies and API DAGs
Picking BFF and RSC strategies by traffic, modeling API dependencies as DAGs for parallel fetching, and knowing when to extract a separate BFF service from your Next.js app.
Agentic UI: When AI Stops Talking and Starts Doing
The shift from conversational to agentic interfaces — and what it means for frontend architecture.
The LLM Agent Debugging Problem: Building Observability from Scratch
A practical guide to debugging LLM agents, with structured logging utilities, trace visualization components, and replay infrastructure you can steal for your own projects.
Building Private & Offline LLM-Powered Experiences: Client-Side AI Agents with Wasm
Learn how to build browser-based AI agents that run entirely on the client side using WebAssembly. This guide covers implementing a RAG system with local LLM inference for private, offline-capable applications.
Schema-First Forms: Zod vs TypeBox for Auto-Generated Type-Safe UIs
Stop writing forms by hand. Learn how to auto-generate type-safe forms from your validation schemas using Zod or TypeBox, and discover which approach fits your project best.
WebGL Performance Power-Up: Three.js, WASM, SIMD, and Lock-Free Concurrency
Building a 50K particle physics system that progressively layers WASM, SIMD, and Web Workers on top of Three.js. Real benchmarks, real code, real trade-offs.
We Benchmarked JS vs Wasm for WebGL — Here's What Actually Matters
A benchmark-driven comparison of JavaScript vs WebAssembly for WebGL workloads. We tested particle systems, mesh generation, and physics simulation across 1K to 1M elements. The results were not what we expected.
