Projects
Chronological notes on projects I am building: what is new, what changed, and where the public artifact lives when there is one.
local semantic memory for agents
The current Enzyme line is a Rust CLI that compiles Markdown workspaces into a local concept graph so agents can retrieve through precomputed catalysts instead of brute-force file search. It is the runtime-shaped version of a project that began as Reason, moved through Obsidian and Electron, then became a CLI-first memory layer.
chat with your vault, with evidence
The current Obsidian plugin brings the runtime back to where the project started: a sidebar chat agent grounded in vault context, clickable quotes, graph-aware retrieval, and local-model support.
memory for app activity, not just vaults
A track for generalizing Enzyme beyond Markdown vaults: app conversations, traces, recipes, and typed activity collections that can expose catalyst-style retrieval to product developers.
handwriting layer for Onyx Boox tablets
App for Onyx Boox e-ink tablets that overlays a full-screen handwriting layer over active apps, including Obsidian, and uses on-device handwriting recognition. Solves the fragmentation between good handwriting UX and existing knowledge management systems. Topped both r/obsidianmd and r/Onyx_Boox on launch; also supports audio recording and timestamp-synced handwriting for use with Aside.
native shell around local memory
Experimental SwiftUI wrapper around the Rust CLI, Digest, and local model resources. The exploration is whether a local-first command-line product can feel approachable without hiding the filesystem and subprocess machinery that make it trustworthy.
tiny vault-chat agent with prefetch
Compact TypeScript agent that talks to an Obsidian vault using Enzyme context before the model starts searching. The point is to replace long, expensive explore loops with a few targeted turns.
open-source RAW photo culling in Rust
Open-source photo culling tool built in Rust that browses thousands of RAW files far faster than Finder. Designed as a replacement for $150/year Photo Mechanic software for high-volume photographers.
round-based matchmaking for IRL events
Round-based and survey-powered matchmaking platform for IRL events. Administered live on-call using Claude Code and iterated over three speed dating events in NYC in three months, totaling 1000+ attendees.
vault-native meeting capture
TUI and skill that records call audio alongside a text editor with timestamped memo lines. Post-meeting, it transcribes audio on device and uses Enzyme in an agent harness to enrich the final artifact with relevant context from other Markdown. Replaces Granola for my workflow by letting me write tangential ideas whose connections get fleshed out after the meeting.
cheap flights to fresh powder
Search tool to quickly find cheap flights to fresh powder at skiing and snowboarding resorts from major metro areas. The build involved flexible flight search, snow-first filtering, hub-based destination modeling, and rate-limit-aware caching. 1M impressions on X.
moving the runtime out of the Electron shell
Before the Rust rewrite, Enzyme moved into a Python CLI focused on feature parity, workspace indexing, and embedding/search performance. This was the bridge from app-shaped prototype to agent-facing local runtime.
a whiteboard for steering AI tone
Hackathon demo for controlling AI conversation behavior in real time — like DJ mixing tracks, but for personality, tone, and response style. Combined a whiteboard/timeline interface with voice and generative AI APIs.
standalone local indexing experiments
After the first Obsidian plugin, Enzyme became a standalone Electron app around local indexing, settings/auth, recipes, and workspace views. That phase clarified what belonged in UI and what needed to become a lower-level runtime.
visual moodboards for worship leaders
Electron/visual moodboard experiment for immersive responsive visuals: image pools, autoplay, waypoints, sliders, and layout controls. A product-design thread around ambient media, ritual, and live presentation contexts.
conversational playlist creation
Pioneered early agentic technology for AI Playlist, Spotify’s prompt-based playlist creation feature. Worked on token- and latency-efficient agent architecture, playlist generation, synthetic data, model distillation, and safety approaches for adversarial or policy-boundary prompts; some of this agentic curation architecture was adopted into AI DJ.
the original vault-chat lineage
The first working Enzyme lineage was Reason: an Obsidian AI/RAG plugin for markdown chat, source embeds, Dataview/content extraction, and navigable context. The current runtime descends from this plugin-shaped attempt to make a vault usable by agents.
playlist recommendations in the listening loop
Led ML work for Smart Shuffle and its predecessor Enhance: real-time candidate generation, re-ranking, and recommendation systems that insert personalized track suggestions directly into user-created playlists.
playlist completion for Premium users
Led ML for Enhance from heuristic experiments through production candidate generation and re-ranking systems. The feature rolled out to Premium users and later became part of the path toward Smart Shuffle.
production ML for spoken music control
Built LSTM-based voice modeling work for Spotify voice experiences, including training/evaluation pipelines and offline metrics for voice user satisfaction. Earlier Spotify work also included mood-based algorithmic playlist data pipelines during a 2017 internship.
