What I'm looking for

I'm looking to build production automation, systems integration, and applied AI solutions where I can own architecture through maintenance and deliver measurable operational efficiency.

At Zangari, I own 10+ production automation systems serving approximately 500 condominiums. I build RPA bots, document-processing pipelines, APIs, and applied AI solutions that remove repetitive operational work—from CAPTCHA-enabled certificate issuance to RAG-based document Q&A.

I've unified WISE, AHREAS, and Google Drive behind a single API, built a 29-endpoint records platform with legacy SOAP integration, and reduced RAG token consumption by 30–60%. Previously at Sitel, I resolved business-system and antivirus support tickets within SLA across phone, email, chat, and remote access.
