I'm a developer engineer at [Samouraï Coop](https://www.samourai.world/), in [samcrew](/u/samcrew), and an [Epitech](https://www.epitech.eu/) graduate.
Contributing to gno.land since May 2025. GnoVM and chain fixes, docs including the getting started guide, and Peer Dev tutorials. I'm passionate about P2P, low level programming, travelling, urbanism and transportation. I'm a curious person who wants to contribute to the greater good. Open for contribution! 🙂

## Activity
## Gno core
Most of my work goes into [gnolang/gno](https://github.com/gnolang/gno), the [gno.land](https://gno.land) monorepo. [All my merged pull requests are on GitHub](https://github.com/gnolang/gno/pulls?q=is%3Apr+author%3Adavd-gzl+is%3Amerged).
## Projects
| Project | What I did |
| --- | --- |
| [GnoVM, explained](https://samouraiworld.github.io/gno-agent-workspace/) | I wrote a guide to how the GnoVM works, for Go developers who have never opened it: parsing, type-checking, the preprocess pass, the stack machine, realm storage and gas. |
| [gnodaokit](https://github.com/samouraiworld/gnodaokit) | A toolkit for building DAOs on gno.land. [I contributed](https://github.com/samouraiworld/gnodaokit/pulls?q=is%3Apr+author%3Adavd-gzl+is%3Amerged) documentation, contributor instructions and a guided setup for the demo DAO. |
| [awesome-gno](https://github.com/gnoverse/awesome-gno) | The curated list of gno.land resources. [I contributed](https://github.com/gnoverse/awesome-gno/pulls?q=is%3Apr+author%3Adavd-gzl+is%3Amerged) new entries, Peer Dev, r/docs and tx-exports among them, and a cleanup of moved links and outdated tutorials. |
## Peer Dev
I teach gno.land on [Peer Dev](https://www.youtube.com/@peerdevlearning), a YouTube channel of developer tutorials, from an empty machine to GovDAO. [Watch the gno.land playlist](https://www.youtube.com/playlist?list=PLJZrQikyfMc-kBojXgAojOz4UQPuq4DiY).
The videos date from 2025, so some commands and screens are out of date. The main ideas still hold.

- [Create your first dApp](https://www.youtube.com/watch?v=z5Qtc0Nuyqg)

Guess today's five-letter word in six tries. Same word for everyone, a new one every day, no wallet needed. [Play puzzle #47](/r/g1rayfgklwl0aspz488wvrcrvt7t2quy6q06lgk2/home:wordle)
## Hearts
**1** so far. [Send one](/r/g1rayfgklwl0aspz488wvrcrvt7t2quy6q06lgk2/home$help&func=Heart): one transaction, one per address, forever on chain. [See who did](/r/g1rayfgklwl0aspz488wvrcrvt7t2quy6q06lgk2/home:hearts).
