Building terminal-first tools, agentic workflows, and self-hosted systems.

I build software that makes dense systems legible:

• terminal workflows that survive machine moves and long sessions
• self-hosted infrastructure that can be rebuilt and understood
• agentic tools that stay useful under real operator pressure
• software that is useful before it is fashionable

Current Focus

• yggterm: Rust-first remote terminal workspace for long-lived operator and agent sessions, now growing into libyggterm: the terminal as an application platform, where an app launched in a terminal takes over the GUI surfaces
• ychrome: the first libyggterm app; run it in a yggterm terminal and the viewport becomes a browser on that machine's network
• cellulose: open-source spreadsheet and financial modeling workspace; compatibility-first, automation-native
• yggdrasil: Debian live-build based ZFS + LXC host operating system

Avikalpa Labs

The company side of the work (incorporating): Practice, a CFA/GMAT practice platform built for my own exam preparation, and Jyas, a research engine that computes classical Jyotish deterministically so its claims can be tested honestly. Both are closed products in development.

Yggdrasil ecosystem

• yggterm: terminal workspace
• ychrome: web viewport, libyggterm pilot
• paper: local-first structured writing and planning workspace
• cellulose: spreadsheet and financial modeling workspace
• yggdrasil: host operating system
• yggcli: guided configuration front door
• yggsync: sync orchestrator
• yggdocs: ecosystem docs

Agentic and terminal tooling

• codex-litellm: maintained LiteLLM patchset for the Codex CLI. In maintenance mode; the economics moved my daily agent work elsewhere, but it stays alive for the Codex surface and can be revived when the utility returns
• codex-session-tui: terminal-first session explorer and repair tool for Codex conversations
• thunderbird-cli: terminal workflow around mail search and operations

Small focused utilities

• runtime-environment-flags: tiny runtime flags for JavaScript environments
• dav-manager: DAV and contacts tooling

Also Writing About

Outside the code itself, I am interested in:

• finance and management as systems problems
• public-interest documentation and case synthesis
• writing book-length material from lived observation rather than generic advice

This page is intentionally simple. I would rather show a few coherent systems than present a crowded wall of claims.
