I am a Full-Stack Developer specializing in connecting existing business infrastructure, web applications, and backend systems with advanced AI technologies. I bridge the gap between traditional engineering and cutting-edge Large Language Models (LLMs).

My Core Technical Stack Includes: • AI Integration: OpenAI API, Anthropic Claude API, Google Gemini, Vector Databases • Backend & Architecture: Java, PHP, Groovy & Grails, Node.js • Databases & Queries: SQL, PLSQL, Database Optimization • Orchestration & Workflow: API Design, Webhooks, JSON/RESTful services I focus on building production-grade AI solutions—not simple mock prototypes. Let's discuss how we can bring robust AI features into your application securely.
