I am Aldian Fazrihady, a Senior Freelance Full Stack Developer and AI Application Engineer available via Upwork.

- Property Management & Tenant AI Portals: Automating maintenance triage, vendor dispatch, and lease Q&A across Yardi, AppFolio, Buildium, and custom portals.
Frequently Asked Questions
Can a freelance programmer build a natural-language property search like "3-bed house near top elementary schools with a backyard office under $850k"?
Yes. I combine LLM query decomposition (extracting structured bedroom/price/school-rating SQL & PostGIS filters) with multimodal photo/description `pgvector` similarity search.
