Ph.D. student @columbia working on Security, Crypto, and AI/ML

Columbia University

Key Strengths

Extensive personal project experience in blockchain-related technologies (ZKP, EVM, symbolic execution).
Demonstrated proficiency in Rust, C++, Python, and Shell scripting, which are highly relevant for blockchain development.
Deep understanding of low-level systems and security concepts, as evidenced by projects like MyZKP, zkFuzz, Gymbo, and MyDisassembler.
Experience with Solidity and Circom indicates direct exposure to smart contract and ZKP circuit development.

Cultural & Operational Fit

Cultural Fit Analysis

The candidate's project portfolio shows a strong inclination towards research-oriented and foundational development in blockchain and security, which aligns well with a deep technical culture. The diversity of projects, particularly in ZKP and EVM, suggests a proactive and self-driven individual. However, the lack of team-based projects or collaborative experience in the provided data makes it difficult to fully assess cultural fit in a team environment.
