Senior AI/ML Engineer building end-to-end production machine learning and LLM systems.
What I'm looking for
I’m a Senior AI/ML Engineer with 8+ years of experience architecting and delivering production-grade machine learning systems, data platforms, and intelligent solutions across healthcare, fintech, and consumer technology. I specialize in building end-to-end AI systems that combine large language models with retrieval-augmented generation, recommendation/ranking, predictive modeling, computer vision pipelines, and real-time inference services—grounded in latency, model quality, compliance, data trustworthiness, and cost efficiency.
I’ve led the design and delivery of production-grade AI for healthcare workflow automation and intelligent decision support, building end-to-end LLM applications using OpenAI APIs and orchestration with LangChain/LangGraph, plus RAG pipelines with embeddings, vector search, hybrid retrieval, reranking, and knowledge-grounded response generation. I also build scalable training, inference, evaluation, and analytics pipelines using MLflow-style MLOps practices, batch/near-real-time data workflows (Spark/Airflow/Kafka patterns), and cloud-native backend services (FastAPI, Docker, Kubernetes) to ensure reliable deployment, monitoring, drift detection, and continuous optimization.

Senior AI / ML Engineer
Notable Healthcare
Feb 2023 - Present (3 years 4 months)
Led design and delivery of production AI systems for healthcare workflow automation, intelligent decision support, and operational optimization. Built end-to-end LLM/RAG and agentic workflows with evaluation, monitoring, and scalable data/serving infrastructure.
Designed and operated large-scale data and machine learning pipelines supporting personalization, recommendation/ranking, and product analytics on a consumer fintech platform. Built ETL/ELT, near-real-time ingestion, and evaluation/experimentation workflows to measure and improve model and business outcomes.
Contributed to production systems for high-volume user activity, real-time workflows, and large-scale operational data processing. Built backend services and supported ML-adjacent workflows (classification, ranking, behavior analysis) with reliability-focused debugging and incident response.
