Hey, I'm Luân (Lunor) 👋

Backend engineer & blockchain developer. Interested in how things work under the hood.

I build backend systems, explore storage engines and performance, and enjoy contributing to developer tools and open-source projects. Lately, I've been diving deeper into Rust, Solana, and native tooling written in Go.

You can reach me on LinkedIn or by email. I also read and share interesting engineering content on daily.dev.

Building

• bolt-tui — A Go/Bubble Tea terminal UI for browsing and editing BoltDB buckets and key-value data.
• FastAPI Simple Boilerplate — A minimal backend starter with FastAPI, SQL and MongoDB, uv, Docker, and CI checks.

Open-source work

• go-ethereum (Geth) — Fixed pruned-history error handling for log queries starting at the genesis block, ensuring the correct error is returned on pruned nodes (PR #31941, merged).
• Mayoi — Fixed a Linux/GTK crash caused by menu updates during rendering. Deferred native menu updates, prevented stale updates, and added regression tests (PR #55, merged).
• Microsoft Edit — Proposed mouse-hover highlighting behavior for the terminal editor (PR #799, closed).
• BNB Smart Chain — Fixed archive-mode transaction history configuration to preserve user-defined settings and prevent unintended full-chain transaction reindexing. (PR #3624, merged)
• Stacks Core — Fixed Clarity VM error formatting to suppress empty Stack Trace sections. Originally proposed in PR #6421; the fix was carried forward by maintainers and merged via PR #6628.
• Umbrel — Fixed photo upload date handling by preserving original file modification timestamps when capture metadata is missing. Added timestamp validation, metadata precedence handling, and regression tests. (PR #2281, open)

Exploring

• DefiLlama Adapters — Fork of DefiLlama's community-maintained DeFi data adapters.
• solana-go — Fork of the Go SDK and RPC client for Solana.

Tools I work with

• Languages: Go, Rust, Python, TypeScript, JavaScript, Solidity
• Data & messaging: PostgreSQL, MongoDB, SQLite, Pebble, Redis, RabbitMQ, NATS, BullMQ
• Blockchain: Ethereum / EVM, Solana, smart contracts
• Infrastructure: Docker, AWS, GCP, Git

I'm always interested in a good conversation about backend architecture, storage systems, or Web3 protocols.
