Summary
🤩
Rockstar🎓
Top SchoolAshutosh Ahelleya is a Security Software Engineer based in London with nine years of hands-on experience in applied cryptography, red teaming, and building resilient cloud and decentralized systems. He has led CTF teams to top global rankings, authored cryptography challenges and writeups, and maintains an open-source Crypton repo that implements and explains real-world crypto attacks used in CTFs and research. As an early engineer at Capsule Social he designed decentralised authentication and smart contracts for a censorship-resistant social platform, and more recently has focused on infrastructure, platform security, and backend resilience at stealth startups. He combines academic study of post-quantum primitives (SIKE FPGA work) with practical offensive and defensive engineering, caring deeply about privacy and decentralisation of power. Colleagues rely on him to translate cryptographic research into auditable, production-ready systems that withstand adversarial scrutiny.
