I build reliable, high-throughput banking integrations and AI-powered enterprise workflows.

At Backbase, I build cloud-native banking integrations and event-driven platforms that connect core banking systems to the Engagement Banking Platform. I restored reliability in critical concurrent flows and reduced API latency by over 95%, from approximately one second to 50ms.

Previously at TransUnion, I owned batch-processing applications across Angular and Spring Boot, scaling interfaces to 100K+ rows and modernizing service communication with gRPC-Web. I also build AI systems, including an LLM-driven transformation agent and TXNomy, a privacy-first transaction classification engine.
