At Jack Henry, I integrated Banno Digital Banking APIs with backend services to deliver personalized financial experiences across web and mobile applications. I developed integrations for account information, transaction history, customer alerts, and account insights.

I built multi-step AI-powered banking workflows using Python, FastAPI, LangChain, LangGraph, and LLM APIs. These workflows retrieve customer context, interact with approved banking services, and process financial information.

I also implemented response validation and controlled execution mechanisms to support the reliability, accuracy, and security of AI-driven banking operations. My work included payment processing and financial data integrations while maintaining transaction integrity and system reliability.

Before Jack Henry, I contributed to SiBanking at Smiley Technologies, Inc., including core transaction processing, digital and mobile banking features, teller functionality, and imaging capabilities. I also developed and maintained native iOS applications using Swift, SwiftUI, UIKit, and Foundation.
