Stephen Sawyer

Rust-first engineer and IT operator building self-hostable systems that are fast, inspectable, and boring to run.

I work on performance-sensitive software, crypto infrastructure, secure networking, local-first tools, and automation for real operations.

Current default stack:

Rust for production systems, CLIs, network services, protocol work, and performance-critical paths.
PostgreSQL for durable state, audit trails, queues, analytics, search, and reporting.
Leptos, Axum, Tokio, and SQLx for Rust web apps and operator surfaces.
Python for automation, scripts, prototypes, bots, data work, and glue, managed with uv, Ruff, pytest, and checked-in pyproject.toml config.
Shell and PowerShell for deployment, diagnostics, and cross-platform IT operations across macOS, Ubuntu, and Windows.

FileFerry — Rust encrypted backup CLI with client-side encryption, local and S3-compatible repositories, and scriptable restores.
Callrift — Username-first communications platform for encrypted messages, WebRTC voice, groups, and technical communities.
Pod Tracker — PostgreSQL-first Commander playgroup OS for events, RSVPs, pod generation, deck tracking, and meta dashboards.
status.dunamismax — Rust status and operations dashboard for public site health, host services, deploy history, and project progress.
mtg-card-bot — Python Discord bot for Magic: The Gathering card lookup using live Scryfall data.
Toolworks — Python automation, operational scripts, and durable CLI helpers.
LangIndex — Open-source reference for programming languages and ecosystem tradeoffs.
dunamismax.com — Personal site and portfolio.

Rust first for systems work.
PostgreSQL first for durable application state.
Python where speed of iteration matters.
Security, key handling, logs, retention, backups, and restores are part of the architecture.
The owner should be able to run it, audit it, recover it, and move it.
