Leading the design and implementation of enterprise-scale AI systems that combine retrieval-augmented generation (RAG), Text-To-SQL, LLMOps, and secure Azure cloud architecture to bring generative AI into production across Polaris.

Standardizing LLMOps:

• Establishing a Polaris-wide LLMOps framework governing model selection, evaluation, and lifecycle management. Defining metrics for performance, safety, compliance, value, and cost to ensure reliability, governance, and scalability in AI deployments.

Enterprise RAG Platform:

• Architecting a retrieval-augmented generation platform that ingests and reasons over billions of PDFs, HTML documents, and technical manuals. The system integrates large-scale ingestion, semantic retrieval, and summarization to deliver accurate, citation-backed, and explainable answers in real time.
• Built data ingestion pipelines that normalize heterogeneous content into a canonical schema with blue/green indexing for zero downtime.
• Developed a multi-source retrieval orchestrator blending keyword, vector, and semantic search, performing cross-source deduplication and weighted rank fusion.
• Created embedding and contextual retrieval pipelines using Azure AI Search and Azure OpenAI, enabling grounded, context-aware responses.
• Implemented Clean Architecture in C# (.NET 8) to separate ingestion, retrieval, orchestration, and presentation (API/chat) layers for scalability and maintainability.
• Integrated Semantic Kernel orchestration to support agent chat workflows and downstream interoperability.
• Partnered with infrastructure teams to deploy Managed Identity, ABAC-secured retrieval, and observability pipelines for reliability and compliance.
• Established QA and telemetry loops to monitor retrieval precision, summarization fidelity, and latency across production systems.

Additional AI Initiatives:

• Unstructured-to-Structured Data Pipelines: Transforming CAD drawings and other complex datasets into structured JSON through OCR and computer vision–based object detection and relationship mapping.
• Text-to-SQL API Platform: Building a secure, standardized API for natural language queries using LangChain, Semantic Kernel, FastAPI, and Azure API Management, with Key Vault–based secrets, OpenAPI endpoints, and centralized logging for governance and traceability.

• Designed and productionized a scalable ML feature pipeline by integrating legacy SEQ and Kafka streaming data, enhancing ingestion efficiency and enabling real-time connected vehicle analytics in Snowflake.
• Built general-purpose and advanced features (e.g., engine speed, wheel speed, battery trends, horsepower estimation) powering high-impact ML use cases such as software anomaly detection, battery health monitoring, and targeted marketing campaigns.
• Developed and deployed an end-to-end software anomaly detection ML model, delivering an estimated $350K in annual ROI and significantly reducing diagnostic time for service teams. Integrated the model into a stakeholder-facing Streamlit app with CRM access for seamless operational use.
• Investigated battery health by analyzing voltage patterns across vehicle lifecycles, identifying trends linked to failure, trickle charger behavior, and replacement events. Insights were shared with engineering leaders during a field site visit to inform future product strategy and increase customer battery health.
• Contributed to a targeted marketing use case by profiling customer-registered vehicles, segmenting by chassis type, mileage, and usage patterns to support personalized campaign development and customer behavior analysis.
• Created a vehicle analytics dashboard in Streamlit for VIN-level diagnostics, integrating real-time and historical telemetry, fault codes, and ML results, enabling data-driven insights for cross-functional stakeholders.
• Partnered with data engineers to implement upstream improvements (e.g., clustering & partitioning strategies), enhancing pipeline performance and reducing unnecessary data volume.
• Authored detailed documentation in Confluence, including architecture diagrams, feature development guides, onboarding resources, and a walkthrough video—ensuring long-term scalability and smooth knowledge transfer across the team.
