What I'm looking for

I'm looking to build scalable, low-latency AI, ML, and Generative AI systems where strong MLOps, distributed data infrastructure, observability, and risk-aware production engineering matter.

At Citigroup, I engineer deterministic agentic KYC onboarding and payment-fraud systems that reduce compliance review time, control inference costs, and strengthen real-time risk detection.

I build production Generative AI infrastructure with LangGraph, FastAPI, pgvector, LoRA, DeepSpeed, vLLM, TensorRT-LLM, Kubernetes, and GitOps. My work has reduced classifier memory footprints by 35%, increased GPU cache efficiency by 22%, and reduced false-positive transaction alerts by 30%.

Previously at Bosch, I built serverless streaming pipelines processing 4.2 TB of machine-sensor data daily and delivered real-time manufacturing quality and predictive-maintenance models. These systems improved product yield by 1.8%, increased quality prediction accuracy by 2.2%, and reduced unplanned downtime by 29%.

I'm focused on scalable, observable ML systems that operate reliably under strict operational and regulatory constraints.
