Designed and deployed digital banking with Backbase, custom workflows (Java, Kotlin, Angular). Led microservice architecture (.NET Core, Node.js, Kotlin) using Kafka, Apollo Router, OPA, PostgreSQL/DynamoDB. Applied DevOps lifecycle (Terraform, AWS Cloudformation, GitHub Actions, Kubernetes on AWS/Azure). Utilized LLMs/OpenAI APIs for code generation, ML model training. Architected observability with Prometheus, New Relic, Azure App Insights, Sentry. Integrated fraud detection (Python/Java/Go, Oracle Cloud Functions).

Led digital banking experiences with Backbase, custom workflows in Java/Kotlin/Angular, microservice architecture (.NET Core, Node.js, Kotlin), DevOps lifecycle (Terraform, AWS Cloudformation, GitHub Actions, Kubernetes), LLM/OpenAI integration.

Performed prompt engineering, technical annotation, OpenAI-powered review in multilingual datasets. Focused on code clarity, error tracing, best practices in concurrent and async environments.
