I build high-availability banking systems and customer journeys for millions of users.

At Publicis Sapient for Lloyds Banking Group, I build Java Spring Boot and Kafka payment, loan, and commercial-deposits systems supporting more than 1M users. I improved PostgreSQL query latency by 27%, reduced transaction failures by 22%, and lowered migration incidents by 38% through Liquibase and Kubernetes CI/CD automation.

I also deliver React/TypeScript customer journeys, secure SSO integrations, and GenAI MVPs using Python, OpenAI, LangChain, and LangGraph. Earlier at ServiceNow, I automated analytics and ETL workflows, saving 15+ hours per week and reducing manual processing from eight hours to 45 minutes.
