ColdFusion/Lucee Expert | Enterprise CFML, REST APIs & AI Integration

Senior ColdFusion (CFML) and Lucee developer with 11+ years of experience in CFML legacy modernization, Adobe ColdFusion migration, REST API development, and AI integration. I help enterprises optimize performance, cut server licensing costs, and connect legacy platforms to modern AI endpoints. ▶ 11+ Years of Senior CFML Engineering: Extensive experience refactoring legacy ColdFusion codebases (CF6 to CF2025) into clean, modern CFScript. ▶ Cost-Saving Lucee Migrations: Seamlessly transitioning enterprise applications from Adobe ColdFusion to open-source Lucee engines to eliminate license fees. ▶ Modern AI API Integrations: Extending legacy CFML systems with OpenAI, Claude, and Gemini APIs for automated workflows, vector search, and custom AI tools. ▶ Performance & Server Optimization: Fixing JVM bottlenecks, memory leaks, high CPU usage, and database slowness in production environments. Core Services & Capabilities: • ColdFusion & Lucee Migration: Migrating applications from Adobe ColdFusion to open-source Lucee with zero downtime. • AI & LLM Integration: Building custom RESTful API integrations between CFML backends and OpenAI, Claude, or Gemini services. • Frameworks & OOP Architecture: Refactoring procedural code using ColdBox, FW/1, Fusebox, and Object-Oriented CFML (CFCs). • Database & SQL Optimization: Tuning complex MySQL and MS SQL Server queries, indexing, and optimizing database schema design. • DevOps & Server Administration: Handling JVM tuning, CommandBox setups, IIS/Nginx configuration, and cross-platform server migrations. Common Client Use Cases I Solve: ✔ Modernizing legacy ColdFusion web applications with AI capabilities, modern UIs, or faster load times. ✔ Migrating enterprise platforms from expensive Adobe ColdFusion setups to Lucee Server setups. ✔ Building modern RESTful APIs on top of existing CFML database layers. ✔ Rescuing and maintaining un-documented, complex ColdFusion applications.
