WORK HISTORY
Lead Technical Developer @T-Mobile
Overland Park, KS, US
I’m currently working on an AI-powered voice assistant platform using OpenAI’s real-time APIs and WebSockets, supporting 600+ customer service flows across multiple channels and improving agent efficiency at scale. I’m also helping design and scale a microservices ecosystem with Java Spring Boot and Python FastAPI, handling millions of daily transactions through a GraphQL gateway and 50+ APIs while reducing latency.On the AI side, I’m implementing a hybrid RAG approach using embeddings and keyword search to improve the accuracy of AI-driven responses across hundreds of internal support articles. I regularly work on performance tuning and API consistency across GraphQL, BFF, and REST layers, cutting external API latency by 25%. I also help define testing and release standards to ensure stable, production-ready deployments across teams.
