Hackathon Project

A security firewall in front of LLM applications that inspects every prompt and response for prompt injection, encoded payloads and data leaks. Eight detectors run in three tiers (unicode and encoding pre-processing, regex and YARA rules, ML classifiers), and a YAML policy engine decides to allow, sanitize, challenge or block in real time. Ships with a live operator console, a feedback loop for true/false positives, and benchmarks reporting precision, recall, F1 and false-positive rate.

• Built a bidirectional LLM security gateway that screens every prompt and response through 8 detectors across 3 tiers (unicode and encoding pre-processing, regex and YARA rules, ML classifiers), mapped to OWASP LLM Top 10 risks.

Public Benefit Project

A cloud-based platform that lets hospitals exchange patient data securely and in real time through a unified API layer, cutting through the fragmentation of siloed hospital record systems. Built with role-based access control and a scalable patient identity system so multiple institutions can coordinate care without compromising privacy.

• Built a cloud-based healthcare interoperability platform enabling secure real-time hospital data exchange using APIs.

Hackathon Project

A hybrid blockchain platform for fighting counterfeit goods across the supply chain: manufacturers mint an NFT for each product, distributors log shipment checkpoints on-chain, and consumers scan a secure QR code to instantly verify a product's authenticity and full chain of custody.
