I build production AI agents and RAG systems that connect LLMs to private documents, databases, APIs, and enterprise workflows. My strongest work is turning an AI prototype into a reliable application with evaluation, security, deployment, and monitoring. I have 6 years of experience delivering production-grade AI and data systems in Fortune 500 retail, consulting, financial-data, and cybersecurity environments. SELECTED RESULTS • Built a real-time multi-agent cybersecurity platform that improved incident-response speed by 40%. • Delivered an image-to-data pipeline with 95%+ accuracy across complex document types. • Built natural-language-to-SQL assistants that eliminated manual query writing and enabled non-technical teams to access live business data. • Developed enterprise document and workflow automation using private data, APIs, cloud services, and human approval controls. WHAT I BUILD • Enterprise AI agents and multi-agent workflows using LangGraph, LangChain, AutoGen, and LlamaIndex • Production RAG systems over documents, databases, and business knowledge • Document intelligence, extraction, classification, and structured-output pipelines • Natural-language SQL and analytics assistants • MCP, API, ERP, and business-workflow integrations • Cloud deployment and production hardening on Azure and AWS DELIVERY I can own the complete lifecycle: requirements discovery, architecture, prototype, retrieval and data layer, API backend, evaluation, deployment, monitoring, and support. CORE STACK Python, FastAPI, LangGraph, LangChain, LlamaIndex, AutoGen, Azure OpenAI, AWS Bedrock, OpenAI, Claude, Gemini, Pinecone, Weaviate, PostgreSQL, Docker, Kubernetes, Databricks, and Kafka. WHY CLIENTS HIRE ME • Production systems, not isolated prompt demos • Full-stack AI ownership from architecture through deployment • Clear communication, documented decisions, and realistic estimates • Enterprise integration experience with private data and controlled workflows Building an AI agent, RAG system, document-intelligence workflow, or enterprise LLM application? Send me the problem, current systems, and desired outcome. I will propose the smallest reliable path to production.

Senior AI/ML Engineer with 7+ years of experience taking AI and ML systems from architecture through production. I combine hands-on Python engineering with RAG, agent orchestration, MLOps, data platforms, and cloud deployment across GCP and AWS. My Upwork record includes $20K+ earned across 20 jobs. What I can deliver: • Production RAG: ingestion, hybrid retrieval, reranking, citations, grounding checks, abstention, evaluation, and latency/cost traces • Reliable LangGraph agents: persistent state, structured outputs, human approval, escalation, retries, timeouts, and circuit breakers • Secure MCP and tool gateways: OIDC, RBAC, least-privilege data access, PII masking, query controls, and audit logging • Python/FastAPI services, Docker, CI/CD, Kubernetes, Cloud Run, Vertex AI, BigQuery, Dataflow, PySpark, and AWS Bedrock • Traditional ML where it is the better fit: forecasting, NLP, computer vision, classification, feature pipelines, model serving, and monitoring Public engineering evidence includes four tested reference implementations: a RAG Quality Workbench, a reliable LangGraph support agent, a secure multi-connector MCP gateway, and an AWS Bedrock RAG API. These demonstrate production-minded architecture without exposing client source code or data. My production background includes retail forecasting and hierarchical ML systems, PySpark feature pipelines, TensorFlow training/inference, policy intelligence and semantic search, Vertex AI embeddings, Cloud SQL, Dataproc, BigQuery, and multi-environment delivery workflows. I have worked independently and with Open Insights, Capgemini, and Hughes Systique. Google Cloud Professional credentials earned: Cloud Architect and Machine Learning Engineer. I start by confirming the business outcome, data and integration constraints, acceptance criteria, security boundaries, and measurable evaluation plan. I then deliver in transparent milestones with tested code, deployment guidance, observability, and maintainable handover documentation. Send me your current problem, stack, constraints, and definition of done, and I will propose a practical path to production.
