Software Architect.Agentic Engineer.Dad.

A little about me:

Hi! I'm Corwin. Welcome to my personal site!

I work at Slalom in Seattle as a Senior Software Architect.

I focus on developer experience, frontend platforms, people leadership, and AI-assisted engineering workflows that help teams ship maintainable software without losing control of the work.

Technologies I love

I am a full-stack architect with a passion for frontend systems, internal platforms, and tools that make teams faster.

Here are a few of the technologies and workflows I work with and love.

Currently building toward

One of the things I love most about software engineering is turning repeated friction into a calmer workflow for the whole team.

Feel free to check out my links below to get to know me better.

Featured projects

A few of the developer tools and experiments I've been building around agent workflows, multi-repo coordination, and lower-friction product teams.

VS Code extension

oil.code

A VS Code extension inspired by oil.nvim that lets you edit your filesystem like a normal file so common file operations feel fast and keyboard friendly.

Built for developers who want an oil.nvim-style workflow without leaving VS Code.
Supports create, move, rename, delete, preview, and directory navigation directly from the editor.

CLI developer tool

Arashi

A Git worktree manager for meta-repositories that helps keep related repos aligned while working across a shared feature branch and workspace.

Designed for multi-repo development and spec-driven workflows.
Includes commands for creating, switching, syncing, and setting up coordinated worktrees.

tmux integration

coding-agents-tmux

A tmux plugin and CLI for tracking, monitoring, and jumping between terminal coding-agent sessions, with support for busy, idle, and waiting states.

Makes it easier to manage multiple agent sessions from a single tmux workflow.
Supports pi, opencode, and codex session discovery, switching, popups, and status summaries.

pi ecosystem

pi-extensions

A collection of installable pi extensions that explores small but useful workflow improvements for the pi coding agent experience.

Includes packages for asking user questions, copying code blocks, interactive review, and Vim-style quit commands.
A place for experimenting with pragmatic extensions that make pi more ergonomic day to day.
