## Selected work

### Mac Messages MCP

Repository: https://github.com/carterlasalle/mac_messages_mcp

A local-first Model Context Protocol server for reading, searching, analyzing, and sending through macOS Messages. The portfolio reports more than 44,000 package downloads. Message data stays on-device and the Messages database is opened read-only.

Technologies: Python, MCP, SQLite, macOS.

### treecat

Repository: https://github.com/carterlasalle/treecat

A Go CLI and interactive terminal UI that prints a recursive directory tree and syntax-highlighted selected file contents. It is designed for sharing code context with language models, documentation, and code review. Distribution includes Homebrew and native Linux packages with automated cross-platform releases.

Technologies: Go, terminal UI, Homebrew, GoReleaser.

### NetSift

Repository: https://github.com/carterlasalle/NetSift

A dependency-free packet-capture explorer for PCAP and PCAPNG files. It defensively decodes common protocols, provides a compact non-executable filter language, emits deterministic table and structured output, and treats malformed input as explicit data or precise failure.

Technologies: Python, PCAP, PCAPNG, networking, TLS, DNS.

### PixelChangeCheck

Repository: https://github.com/carterlasalle/PixelChangeCheck

A Rust screen-sharing system that detects and transmits changed image regions. It supports direct QUIC viewers, relay-backed NAT traversal, adaptive quality, a native viewer, and browser viewing through MJPEG.

Technologies: Rust, QUIC, LZ4, MJPEG, networking.

### EmojiStega

Website: https://emojisteg.is-a.dev

A steganography tool that hides encrypted payloads inside emoji variation selectors, exploring a covert channel in Unicode.

### Stamina Timer

Website: https://staminatimer.com

An AI-assisted training product built around structured sessions, progression, analytics, expiring shares, and optional authenticated coaching.
