• Red teamed Mistral's Le Chat — bypassed content safety guardrails across political disinformation, weapons synthesis, and cyberattack methodology. Extracted full production system prompt despite explicit anti-extraction instructions. Responsibly disclosed to Mistral (April 2026). • Red teamed Sarvam AI's Indus 105B — disclosed system prompt extraction, multilingual phishing content generation, and ANSI escape injection. Sarvam acknowledged findings; published case study forthcoming. • Red teamed KissanAI's Dhenu agricultural chatbot — uncovered full system prompt extraction in 4 turns, [Language] tag architectural routing flaw, and persona override vulnerabilities.

About

Self-taught ML developer. Started from mechanical engineering, figured out the rest along the way. Currently building production ML systems at Qriocity — computer vision, GANs, LLMs, agentic pipelines, across fintech, retail, and ecommerce clients. On the side, I red team LLMs. Disclosed vulnerabilities in Sarvam AI's Indus, Sarvam 105b model and KissanAI's Dhenu — findings included system prompt extraction, prompt injection, and architectural injection. Interested in AI security, responsible disclosure, and building things end-to-end.
