PROJECTS

Intelligent Context Compression Middleware

constproject={
name:'Intelligent Context Compression Middleware',
tools: ['Python', 'PostgreSQL', 'LLMLingua-2', 'RECOMP],
myRole:Contributor, Open Source,
Description: Designed strategy-agnostic context-compression middleware for Guepard, an open-source text-to-SQL agent, partitioning the context window into a four-zone architecture. The best strategy losslessly reclaimed 15-30% of the usable context window. Built a reproducible benchmarking harness replaying 35 annotated multi-turn sessions against live PostgreSQL databases, evaluating it against LLMLingua-2 and RECOMP baselines.,
};

SMARTSHIELD

constproject={
name:'SMARTSHIELD',
tools: ['Zeek', 'OpenArgus', 'RabbitMQ', 'ELK Stack', 'Docker', 'NestJS', 'React', 'PyTorch', 'FastAPI', 'Go],
myRole:Backend & AI Developer,
Description: Secured 2nd place in the CS Challenge at IEEE TSYP12 competition with our project which is an AI-driven cybersecurity platform designed to enhance automatic threat detection, classification, and response. It offers an end-to-end cybersecurity solution from log extraction to automated report generation.,
};

INSecAT

constproject={
name:'INSecAT',
tools: ['Python', 'NestJS', 'React', 'FastAPI', 'Docker', 'Shodan API', 'Nmap', 'Snyk', 'OWASP ZAP],
myRole:Project Manager & Lead Developer,
Description: Directed development of INSecAT, a comprehensive web application security scanning platform. The toolkit provides both external (black-box) and internal (white-box) security assessments by integrating multiple cybersecurity technologies.,
};

Klippy

constproject={
name:'Klippy',
tools: ['Python', 'Small Language Models', 'Local Inference],
myRole:Creator,
Description: Built a fully local AI assistant powered by a small language model with permission-scoped file system access, designed for compliance and sensitive-data workflows without sending data to third-party APIs, accelerating those workflows 30%+.,
};

X2X Plugin for Hexabot

constproject={
name:'X2X Plugin for Hexabot',
tools: ['TypeScript', 'Node.js', 'Hexastack],
myRole:Full Stack Developer,
Description: Won 1st place at Orange AI Hackathon with the X2X plugin for Hexabot, a visual chatbot conversation flow management tool. X2X is a set of plugins and helpers that enables conversion between different modalities, such as speech, text, and vision.,
};

Phishing Domain Detection & Creation

constproject={
name:'Phishing Domain Detection & Creation',
tools: ['Dnstwist', 'Python', 'Ruby on Rails', 'Bootstrap],
myRole:Cybersecurity Engineer Intern,
Description: During my internship at Pwn&Patch, I integrated a component for phishing domain detection (for blue teaming) and phishing domain creation (for red teaming), reaching 95% accuracy using dnstwist-based domain-permutation techniques, while also allowing the generation of similar-looking domains for security testing.,
};

DEBIAS

constproject={
name:'DEBIAS',
tools: ['Python', 'Recommender Systems', 'Machine Learning],
myRole:Developer,
Description: Built an end-to-end e-commerce recommendation system accounting for trends and short- and long-term user actions, handling the cold-start problem through techniques beyond simple product embedding and retrieval.,
};

SmartSight

constproject={
name:'SmartSight',
tools: ['Raspberry Pi 5', 'MQTT', 'PyTorch', 'Expo Go', 'React Native],
myRole:Backend & IoT Developer,
Description: Built AI-powered glasses on a Raspberry Pi 5 implementing object detection, depth estimation, and a smart decision system that translates visual scenes into audio instructions over a companion mobile app, to help visually impaired individuals navigate their environment.,
};
