• Create and implement SQL automation scripts to update the Computer-Assisted Mass Appraisal (CAMA) database and integrate valuation models into the CAMA system.
• Develop citywide retail property valuation models by running multiple cases in parallel, recording performance indicators, automating data flow between stages, and implementing automated variable selection processes and data pipelines to enhance accuracy, consistency, and efficiency.
• Build assessment district maps to illustrate property type composition and help assessors become familiar with their districts, automating ArcGIS map generation, PDF compilation, and indexing for seamless navigation between borough-wide and district-level maps.
• Design comprehensive model validation frameworks that systematically verify properties against exclusion criteria across multiple systems and cross-check valuation results against historical data and benchmarks.
• Provide ad-hoc guidance to unit staff on methodology, programming, data analysis, and model development to strengthen team capabilities and improve modeling outcomes.
