Summary

Rockstar🎓
Top SchoolOmar Espejel is a crypto developer and developer advocate with 7 years of experience, currently driving AI and developer education efforts at the Starknet Foundation from Dubai. He combines deep Cairo and StarkNet smart-contract expertise with prior ML developer advocacy at Hugging Face, contributing to widely used community resources like starknet-cairo-101 and the community-driven Starknet book. Omar has led open-source public-goods work—securing ~$75k in grants for Restake Watch—to build transparency and risk-assessment tooling for restaking ecosystems. His background spans product management and data science roles across Latin America, co-founding a deep-learning education initiative and producing research-grade data analysis for academic and NGO partners. Equally comfortable refactoring core contract logic or writing integration tutorials, he bridges low-level protocol engineering with practical developer education. A multilingual contributor (ES/EN), he brings a rare mix of academic research rigor, product sensibility, and hands-on cryptographic engineering.
