Amazon Enterprise Security Analytics Engine

Architected a search platform to analyze a 1.2M+ record breach dataset, uncovering data exposure risks for executive personnel and triggering an AWS Security response. Engineered a migration from local storage to Amazon RDS (MySQL), optimizing query latency and building a scalable infrastructure for real-time risk assessment. Featured a Next.js frontend paired with a FastAPI backend, leveraging serverless Python to handle high-concurrency traffic with minimal maintenance overhead and sub-second retrieval times.

Ranking Algorithm Integrity Framework

Zillow Audit

Reverse-engineered engagement-based ranking systems to identify logic flaws in automated verification and rate-limiting controls. Built a high-concurrency simulation suite that increased property visibility by 22,000% (2 to 450+ views) and generated 400 synthetic interactions to audit “Hot Home” triggers. Leveraged custom OSINT tooling to harvest and validate 2,000+ email addresses for account creation, achieving a 98% success rate. Published a 10-page technical research paper detailing system vulnerabilities and architecting defensive mitigations against engagement fraud.

Built a real-time humanitarian intelligence dashboard in 36 hours that maps the mismatch between disaster risk and humanitarian funding across 53 countries. Utilized distributed PySpark ETL pipelines and XGBoost to aggregate 1,400+ disaster records into predictive risk models, flagging the crises most underfunded relative to severity. Integrated AI-generated briefings with historical pattern matching, risk scores, coping capacity analysis, and recommended next steps — powered by data from INFORM Risk Index, FTS (OCHA), CBPF, and EM-DAT with a Mapbox GL JS frontend for interactive geospatial visualization.

Automated Intelligence Crawler & Resilient Pipeline

Engineered a high-speed ingestion engine processing 1,000+ pages at 50 pages/min, achieving a 95% extraction rate across unstructured web data. Implemented a custom session-handling system to bypass Cloudflare BIC protections via dynamic cookie rotation, ensuring 24/7 uptime for data collection. Normalized over 10,000 unstructured records into a relational schema, enabling efficient SQL-based behavioral analysis and threat intelligence.
