About Nagendra Nirnakar

Engineering leader specializing in AI/ML platforms and risk systems with extensive experience at PayPal, eBay, Intuit, and Wells Fargo. I design and scale cloud-native ML infrastructures that power fraud detection, identity security, and compliance risk management — handling billions of events daily with <50ms inference latency.My expertise spans the full ML lifecycle:Feature Engineering & Stores → Spark/Flink pipelines, Redis & Feast, ensuring training–serving consistency.Model Training & Deployment → Supervised/unsupervised models (LightGBM, CNNs, autoencoders), ensemble architectures, ONNX Runtime for ultra-low-latency scoring.MLOps & Observability → MLflow, CI/CD, OpenTelemetry, Prometheus/Grafana/DataDog for model drift, PSI monitoring, and SLO/SLI tracking.Cloud & Distributed Systems → AWS (SageMaker, EKS, Lambda, EMR), GCP, Azure, Kubernetes, Terraform, Kafka, Spark, Ray.Beyond technical depth, I thrive in cross-functional collaboration — translating complex risk needs into scalable solutions while mentoring teams and embedding best practices in CI/CD, SRE, and ML engineering.I’m passionate about using ML and distributed systems to reduce fraud losses, strengthen trust, and drive business growth in financial services.
