Security Researcher Solidity

I have a background in IT, software development, networking, and cloud technologies, with a Master’s degree from INPTIC. I worked on projects involving mobile applications, microservices, Kubernetes, and Istio, and later worked as an IT Manager at Zzenz.

Since 2024, I’ve shifted my focus toward smart contract and DeFi security. I’ve participated in Sherlock and Code4rena audits, finding and reporting multiple High and Medium severity vulnerabilities. I’m currently looking for a remote position in smart contract security, blockchain security, or Solidity development where I can use my technical background and continue growing as a security researcher.
