## About

I’m a security researcher and self\-taught AI engineer with experience in machine learning, fine\-tuning, retrieval\-augmented generation \(RAG\), data engineering, and application security As the founding engineer and employee \#1 at Vahini Technologies, I owned the AI, ML, data, and software stack for an IMU\-based handwriting pen\. My work covered sensor\-data pipelines, noise reduction, CNN and Bi\-LSTM recognition models, full\-stack development, and product integration\. This work contributed to 2 granted Indian patents, Nos\. 584433 and 604895, covering handwriting recognition and structured digitization\. I am the Lead inventor on both of them\. My security work spans web, mobile, and API penetration testing, vulnerability assessment, secure code review, and product security\. I’m also interested in firmware reverse engineering and the security of connected devices\. My current interests include LLM red teaming, jailbreaks, prompt injection, agent observability, interpretability, and sandbox security\. Some milestones along the way: • 2 granted Indian patents as Lead Inventor • USD 25,000 Y Combinator Startup School India grant • 1st, SANS NetWars Tournament Core • 1st, OWASP AppSec Bangalore BeSec CTF • 4th, Cloud Security Alliance Bangalore CTF • 6th, SANS Veterans Day CTF • 7th, Amazon CTF I hold GIAC GSEC, GFACT, CEH, eJPT, and ISC2 CC certifications and am preparing for GIAC GCIH\. I’m open to AI safety and AI security research position and roles in AI engineering, application security, offensive security\. I’m based in India and open to remote and international opportunities\. I built Zenith, an AI\-powered security assessment platform with more than five early clients, alongside a vulnerability scanner using a local open\-weight model and workflows for testing coding agents\. I also worked with Andhra Pradesh government stakeholders and served as liaison for our IIT Tirupati collaboration\.
