Blockchain Engineer

I’m a Blockchain Engineer and Data Scientist with three years of experience in smart contract development and machine learning. My work spans building decentralized applications, security auditing tools, and provable machine learning frameworks.

At Nethermind, I contributed to Project Fossil, enabling trustless verification of L1 contract data on L2. I also worked on Yokai, a centralized AI-driven security auditing tool for Cairo-based repositories.

As a Data Scientist at CrunchDAO, I developed machine learning models for financial markets, optimizing trading signals for profitability.

I’m also actively involved in open-source projects, such as:

  • Orion – A framework for Provable Machine Learning, where I implemented core ML operators in Cairo.
  • AFK-MonoRepo - Decentralized social built with Nostr and powered by Starknet account abstraction.
  • Shinigami - library for generic Bitcoin Script execution in Cairo, enabling the generation of STARK proofs for Bitcoin Script computation and Bitcoin transaction execution.
  • Lilypad – A lightweight FVM oracle that integrates Bacalhau for off-chain computations, expanding smart contract capabilities.

I'm looking for Blockchain Engineer or Smart Contract Developer roles.
