I am an Applied AI Engineer and Full-Stack Developer with a track record of architecting production systems. From deploying multi-modal LLM pipelines with OpenAI Whisper, GPT-4o, and TTS to architecting scalable backend systems with NestJS, Laravel, Node.js, and Flutter, I bridge the gap between advanced artificial intelligence and real-world enterprise applications.

My work prioritizes structured prompt engineering, agentic workflows, vector search (RAG), and cost-efficient token governance. Whether creating automated HR mock interview engines, clinical medical viva bots, or high-throughput NestJS AI microservices, I deliver reliable, performant, and explainable intelligent software.
