I build open-source tools across the stack โ from Rust CLIs and Go services to AI SaaS and native Swift apps. Most of my work is scratching my own itch, then open-sourcing it. If you find it useful, even better.
๐ฏ Focus AI tooling ยท personal automation ยท web3 infra ยท systems programming
๐จ Style Ship small, iterate fast, polyglot by curiosity
๐ฑ Always Learning a new language / framework every quarter
๐ฌ Reach me Issues / PRs welcome on any repo
25+ public repos across AI, Web3, systems, native, and personal infra. All descriptions below are pulled from the repos themselves.
| Repo | What it does | Stack | Stars |
|---|---|---|---|
| Inflowee | Personal monitoring SaaS โ define a goal, plug in sources, get AI-generated daily briefs in your inbox. Local-first SQLite by default, Postgres in prod, with an MCP server for agent integration. | Next.js 16 ยท React 19 ยท Prisma ยท Inngest ยท MCP SDK |  |
| digi-life | "Digital life for everyone" โ personal data service. | NestJS ยท TypeScript |  |
| Repo | What it does | Stack | Stars |
|---|---|---|---|
| welinker | A personal-automation message bus. Normalizes inbound messages (WeChat, HTTP) into typed events, routes to local or remote agents (Claude, Codex, Gemini, DeepSeek, Qwen, Kimi), and records the full lifecycle. Local-first WebUI control panel. | Rust ยท Tokio ยท WebUI |  |
| live-bot ยท streamix | Streamix โ a desktop control system for Bilibili live streamers. Real-time chat monitoring, rule-based auto-reply, gift / interaction analytics, AI voice companion, and an OBS plugin view. Separate public-release repo for auto-update artifacts. | Rust ยท Tauri |  |
| warp (OpenWarp) | Fully decentralized fork of Warp terminal. Strips the mandatory cloud, opens the AI layer to any OpenAI-compatible endpoint + 6 native protocols, wires in 3rd-party CLI agents (Codex / Claude Code / DeepSeek-TUI), adds a built-in SSH host manager, and fixes CJK / markdown rendering. | Rust ยท Tauri ยท minijinja |  |
| blockchain-rs | Bitcoin-style blockchain from scratch. Implements PoW, UTXO model, ECDSA tx signing, Merkle trees, a UTXO index over sled, and TCP-based P2P propagation. |
Rust ยท sled ยท merkle-cbt |  |
| homebrew-tap | Homebrew tap that distributes my Rust binaries โ brew install Leejaywell/tap/welinker. |
Ruby ยท Homebrew |  |
| Repo | What it does | Stack | Stars |
|---|---|---|---|
| coin-market | Full crypto-exchange microservices monorepo. Independent Go services for exchange, market, user, and jobcenter (each with its own API gateway), shared gRPC contracts, Docker + Kubernetes manifests, and a Vue trading UI. |
Go (go-zero) ยท gRPC ยท Docker ยท K8s ยท Vue |  |
| DGC-backend | Digital-asset trading platform backend, with documented system and business architecture diagrams. | Java ยท Spring Boot |  |
| DGC-admin ยท DGC_frontend | Admin console (Ant Design Pro) and end-user client for the DGC exchange. | TypeScript ยท Vue |  |
| contract-solidity | Smart-contract workspace on Hardhat 3 beta with node:test and viem. Includes Foundry-compatible Solidity tests and Ignition deploy modules (local + Sepolia). |

Rust ยท Swift ยท UniFFI |  |
| ui-builder-backend ยท ui-builder-frontend | Drag-and-drop website builder with a pluggable theme / widget system (themes ship as folders with their own theme.config, scripts, and styles). Originally built for hotel sites; engine + builder UI are independent. |
Java ยท React ยท Ant Design Pro |  |
| Repo | What it does | Stack |
|---|---|---|
| go-redis | A Redis server reimplemented in Go to study the protocol and data structures. | Go |
