Experience

AIML Engineer

Molina Healthcare, USA
May 2025 - Present · 1 year 2 months

Developed and deployed production-grade Generative AI solutions and LLM-based applications for enterprise and consumer products.
Worked extensively with LLaMA, GPT APIs, Hugging Face Transformers, and RAG pipelines for knowledge-intensive applications.
Designed and implemented MLOps pipelines using MLflow, Docker, Azure ML, and CI/CD, reducing deployment time by 40%.
Optimized deep learning models (CNNs, UNet, Autoencoders) for image/video analytics and multimodal AI applications.
Collaborated with cross-functional teams to integrate AI solutions with Microsoft Copilot, Ollama, and internal APIs, enhancing productivity tools.
Performed data engineering tasks including ETL, feature engineering, and preprocessing using Spark, Pandas, and NumPy.
Mentored junior engineers on best practices in ML lifecycle, model monitoring, and cloud deployment.
Implemented a knowledge retrieval augmented generation (RAG) pipeline that improved LLM response accuracy by 35%.
Contributed to Molina Healthcare's internal model deployment framework on Azure, reducing iteration cycles for new models.
