# Projects
Things I've built. Mostly rewriting existing software from scratch to understand how it actually works.
Agents
Agentic coding system that runs directly in Emacs. Three Claude code sessions in split buffers — one plans, one codes, one reviews — connected through a Rust CLI and Elisp orchestrator. Review loop runs until the reviewer approves twice consecutively. No Electron app needed.
Systems Programming
A from-scratch SQLite parser and query engine. Reads raw .db files byte-by-byte,
manually parses B-trees, and extracts rows. Supports SELECT, WHERE,
COUNT(*), and index optimization with B-tree traversal. Part of the "rewrite everything in Rust" movement -
real devs read hex dumps and parse varints manually.
A lightweight Redis server implementation compatible with standard Redis clients. Full RESP protocol support, key-value ops with expiry, transactions (MULTI/EXEC), master-slave replication, RDB file parsing and persistence, and Redis Streams (XADD, XRANGE, XREAD). Basically Redis but I wrote it.
Simple HTTP/1.1 server with GET/POST handling, file upload/download, User-Agent echo, gzip compression support, and multithreaded request handling. Nothing fancy, just works.
Languages & Low-Level
Rust implementation of the Monkey programming language interpreter, based on "Writing An Interpreter In Go" by Thorsten Ball. Full lexer and parser done, working on the evaluator. C-like syntax, first-class functions, closures, a simple object system. Learning interpreters the hard way.
Graphics
Real-time GLSL shader preview inside Emacs. Live preview with hot reload on save, ShaderToy-compatible shaders, mouse interaction, PNG export. Three-layer architecture: Elisp UI, Rust FFI module, and pure Rust GPU library on top of wgpu.
Path tracer with both CPU and GPU acceleration. Monte Carlo sampling, materials (Lambertian diffuse, metal, dielectric glass), camera with depth of field and adjustable FOV, cross-platform GPU via wgpu. Works on your shitty laptop if it has Vulkan/Metal/DX12 - otherwise use your poor CPU.
Tools
Linear.app integration for Emacs with a Magit-style UI. Collapsible tree view by teams, projects, and workflow states. Change status, priority, labels, and assignee via transient menus. Create issues, copy branch names, open in browser — all without leaving Emacs. Pure Elisp.
