What I'm looking for

I seek roles combining security research and full-stack development where I can strengthen defenses, contribute to secure architecture, and grow with collaborative, innovation-focused teams.

I am a Computer Science student and security researcher specializing in vulnerability research, CTF challenges, and threat analysis, with a demonstrated record of responsible disclosures and practical web security work.

I build full-stack web and blockchain solutions, having delivered projects using React, FastAPI, Hyperledger Fabric, TON Blockchain and modern deployment practices; my projects include a RAG document QA system and a chain-of-custody platform.

I combine hands-on offensive security experience—listed on the Wikimedia Security Hall of Fame and multiple CTF and bug-bounty achievements—with strong web development and DevOps skills to design secure, scalable systems and drive practical improvements to digital infrastructure.
