Backend engineer for AI infrastructure and developer experience. Go and Python, with TypeScript and Rust where the work demands it. I ship small, focused, self-contained software: one binary, one config, one deploy.
Kilnx is an htmx-native backend language. A full compiler pipeline in Go (~19K LOC) with SQL-aware static type inference, security analyzer, query optimizer, and LSP server. The runtime ships embedded SQLite, RBAC, WebSockets, and background jobs. Compiles a full web app to a single ~15MB binary. Apache 2.0.
Tessera is a miniature control plane in Rust. Schedules workloads across a fleet of nodes with declarative reconciliation, control/data plane split, and an explicit workload state machine. Built on Dropshot.
Provero is a declarative data quality engine on PyPI. One check definition runs across PostgreSQL, DuckDB, and SQLite. 16 check types, SodaCL import, dbt test export. Continuous monitoring mode with CLI and YAML workflow.
Sprite-Warden is a capability-bound microVM orchestrator for single-session agents. Signed passports bound to VM lifecycle, atomic revocation on migration, full capability-use trace. Part of an agent safety stack with Belltower (hypermedia coordination kernel for multi-agent workflows) and Cordon (capability-based containment).
htmx-devtools is a Chrome DevTools panel for debugging htmx apps: request inspection, swap monitoring, event tracing. Sibling project htmx-vscode-toolkit ships IntelliSense, hover docs, validation, and snippets for htmx across 20+ template languages.
AToolZ is a developer tooling collective covering CLIs (picocrawl, terraxi, turnis, tabra, telvar), MCP servers (flyte-mcp), LSP servers (kitty-lsp-toolkit), and AI agent tooling (scope-guard, oss-kb).
PostCLI is publishing tools for humans and AI agents. Each platform ships as a CLI and an MCP server in the same codebase, so terminals and coding agents drive the same backend (substack, slack, hackernews).
