I validated model performance by analysing key metrics such as Precision, Recall and F1 Score which also includes false positives, true positives, and other classification outcomes, providing actionable feedback to developers for model refinement. Additionally, I conducted end-to-end testing of Web & Mobile banking applications across iOS and Android platforms in all environments — DEV, Staging, BETA, and Production. This included identifying and reporting bugs, usability issues, and security vulnerabilities across a variety of devices and operating systems. Ensured that all developed solutions adhered strictly to functional requirements and design specifications. I also verified system integration with Kubernetes and Kafka topics, including the impact on underlying databases (Spanner / MySQL)
