   I am an AI/ML and Software Engineer passionate about building scalable, high-performance software and machine learning solutions that drive measurable business impact. I design and implement distributed systems, end-to-end ML workflows, and applications that enable real-time insights, automation, and decision-making. My work spans backend development, API integration, and scalable system architecture, combining software engineering principles with applied AI/ML techniques.At Target, I developed real-time fraud detection and recommendation systems that reduced false positives by 25% and boosted customer engagement. I built NLP pipelines to automate customer support workflows, improving efficiency and response accuracy. I also designed computer vision models achieving ~93% classification accuracy using TensorFlow and PyTorch and integrated them into production pipelines for high-reliability applications.I have hands-on experience implementing distributed model training and deployment on AWS SageMaker and Azure ML, while automating CI/CD pipelines using GitHub Actions, Docker, and Kubernetes. I built low-latency streaming solutions with Kafka, Pulsar, and Flink for real-time data processing, as well as anomaly detection systems to monitor data drift and ensure continuous model reliability. Additionally, I developed interactive dashboards in Power BI and Tableau to track KPIs and operational metrics, helping teams make informed business decisions.Collaborating with cross-functional stakeholders, I align software and ML solutions with business goals, optimize performance through hyperparameter tuning, and mentor teams on best practices in both software engineering and ML workflows. My technical expertise spans Python, Java, C/C++, TensorFlow, PyTorch, Scikit-learn, Spark, Databricks, Kafka, Flink, Pulsar, AWS (SageMaker, S3, Lambda, RDS), Azure ML and Data Factory, Docker, Kubernetes, Git, Jenkins, Power BI, Tableau, MLflow, and ELK Stack
