I build AI-native tools and ship them. CLIs, agents, MCP servers, and full-stack web apps. Thirty years in, I build and manage the AI agents that do the heavy lifting: directing more than typing, but close enough to the code to know when something's wrong. What I care about hasn't changed: tools that do one thing cleanly, READMEs a stranger can follow, and code another engineer understands in sixty seconds.
Below is what I've been making lately. If you'd rather ask than read, my site answers questions about me in my own words: haimdimer.com.
- earshot — Turns books into multi-episode podcasts. Next.js 16, Neon, and Cloudflare R2, built to actually listen to.
- code-index — Semantic code search as an MCP server, backed by Milvus. So an agent can find code by meaning, not just grep.
- live-poll-kit — Drop-in live polling with QR codes for talks and classrooms. Vercel plus Neon, five-minute setup.
- postcss
— The CSS transformer behind Tailwind, Next.js, and autoprefixer, and much of the modern web build toolchain.
- burn
— A Rust deep-learning framework and tensor library built for flexibility, efficiency, and portability across backends.
- gitoxide
— A pure-Rust implementation of Git, built as fast and safe command-line tools and libraries.
- sqlfluff
— A modular SQL linter and auto-formatter with support for many dialects.
- sqlglot
— A Python SQL parser, transpiler, and optimizer spanning 20+ SQL dialects.
- marshmallow
— A Python library for converting complex objects to and from simple datatypes, with validation.
- chroma
— A general-purpose syntax highlighter in pure Go, with lexers for hundreds of languages.
- minify
— A fast collection of Go minifiers for HTML, CSS, JS, JSON, SVG, and XML.
- dprint
— A pluggable, configurable code-formatting platform that unifies many formatters behind one tool.
