Technical Developer Advocate
I scale developer ecosystems through code, education, and community.
Starknet Foundation (Current)
Developer Advocate leading ecosystem growth
- Led Starknet Book to 800+ GitHub stars, primary resource for 1000s of Cairo developers
- Organized Re{solve} hackathon from scratch - onboarded 1000s of developers to Starknet, 2x participants vs previous hackathons (Winter, Reignite), 2x submissions, record sponsorship from Cartridge, Xverse, Ekubo, and 15+ partners across Bitcoin, Privacy/ZK, Mobile-first tracks
- Building privacy infrastructure: Tongo integration + ZK attestation toolkit
- Delivered technical workshops at ETHCC, Devcon, ETHPrague
- Secured ~75k USD in grants (Ethereum Foundation + Obol Collective) for Restake Watch
Hugging Face (Previously)
Machine Learning Engineer / Developer Advocate
- Created 4 top-rated AI courses on Platzi (5-star avg across 325+ opinions)
- Authored core educational content: embeddings guide, model fine-tuning, fastai integration
- Scaled NLP adoption through hands-on tutorials and documentation
Key Impact: Took two nascent ecosystems (Starknet, Hugging Face) from early adoption to mainstream developer adoption through technical content, tooling, and community building.
Technical Content: I write code first, docs second. No hand-waving—working examples that developers can fork and ship.
Ecosystem Building: From developer documentation to hackathons to grant programs. I've built the full stack of developer relations.
Code Contributions: I ship production code. Cairo contracts, TypeScript SDKs, Python tooling. I understand what developers need because I am one.
Community: Host of Hacia Afuera, Spanish tech podcast. Built multilingual resources (ES/EN). Developer ecosystems are global.

Code over slides. Working demos over whitepapers. Open source over closed systems.
Developer advocacy isn't marketing—it's engineering that scales through education.
