Experience

1. Architect 1

   American Express

   Jul 2024 — Present · Phoenix, AZ, US

   As an Architect 1 at American Express (Phoenix, AZ), I design and deliver enterprise-scale AI solutions that bridge cutting-edge research with production-ready impact. My focus is on LLMs, transformers, and intelligent retrieval systems, where I specialize in fine-tuning foundational models using LoRA/QLoRA and developing custom Retrieval-Augmented Generation (RAG) pipelines for multiple business search engines.I spearheaded the development of a multilingual smart search and typeahead system that transformed how users navigate a complex ecosystem of products and services. This platform leverages a hybrid retrieval approach built on:1. PostgreSQL with pgvector for dense vector search2. Multilingual sentence transformers for semantic understanding3. Subword-token-based typeahead models for precision autocomplete4. LangChain & LangGraph frameworks to orchestrate modular, production-grade RAG pipelines and reasoning workflowsThis system not only improved search accuracy and latency but also led to a measurable reduction in call center volume by empowering customers with self-service discovery tools.By combining LLMs, retrieval systems, and orchestration frameworks, I build solutions that are scalable, explainable, multilingual, and business-driven—delivering measurable outcomes while pushing the frontier of enterprise-safe GenAI adoption.
