What I'm looking for

I seek roles where I can lead blockchain security efforts, conduct high-impact audits, build tooling and monitoring, and mentor teams within security-focused, collaborative environments.

I am a security engineer focused on blockchain and smart contract security, with hands-on experience auditing EVM and non-EVM protocols, building monitoring systems, and improving proprietary security tooling.

I've led internal and external audits for major protocols, developed invariant testing frameworks and staking/delegation safeguards, and drove improvements to tooling such as bytecode decompilation and dynamic debugging to raise detection efficiency.

I hold an MSc in Cybersecurity and a BSc in Computer Science, and I collaborate closely with product teams, integrators, and audit partners to implement security-first practices and rapid incident response.
