AI/ML Engineer

Vizzda · Arizona

  • Built and deployed end-to-end pipelines for automated real estate document processing, orchestrating Google Document AI, Tesseract OCR and Gemini 2.5 Flash in a 3-source consensus extraction system across Maricopa and Miami-Dade.
  • Created entity resolution and skip-trace systems using fuzzy matching, Bizapedia and the Enformion API — with tuned similarity thresholds, cost-control layers and multi-hop LLC traversal — to identify beneficial owners at scale.
  • Developed a modular multi-county Python pipeline combining external APIs, Playwright automation, LLM structured extraction and rules-based enrichment to produce contact-ready commercial real estate intelligence daily.

Research Assistant

Ira A. Fulton Schools of Engineering, ASU · Tempe, AZ

  • Implemented 6 federated learning algorithms combining FedAvg/FedGmd aggregators with SGD, ASS and SASS trainers, running 432 experiments across IID and non-IID MNIST and medical datasets (REFUGE, LAG) with up to 80% corruption.
  • Diagnosed why FedGmd hurt accuracy by up to 6% at high corruption — the geometric median collapses toward the corrupt majority past 50% — and confirmed it theoretically via RFA breakdown-point analysis.
