Browser-native tools
Built from scratch.
Shipped for real.
Tools, garden systems, and interactive experiments — all zero-backend, all running in a browser tab.
Tools that actually ship.
Dave builds tools that solve real problems — garden planners, prompt engineering workflows, hiking trackers, graph visualizers — all running entirely in the browser with zero backend infrastructure. Every project is a single HTML file or a small static app deployed to GitHub Pages. No server, no database, no cost to run. If it can run in a tab, it doesn't need a cloud.
Stack
The flagship tools.
Three projects that pushed the most — each a self-contained system built over months of iteration.
Prompt engineering workbench with A/B testing, golden response benchmarks, starter libraries, and multi-provider LLM support. Ships as extension, desktop app, and web tool.
Backcountry field log for hiking trips. Weather-aware planning, trail enrichment via OpenStreetMap, nearby trail discovery, and offline-capable gear checklists.
Raised bed planning ecosystem with deterministic 6-factor scoring, companion analysis, build guides, ops guides, and a 12-chapter narrative strategy game.
The rest, in one table.
The flagship builds stay up top. Everything else lives here in a compact, searchable index.
