I take on AI projects that others find too complex — end-to-end systems where the challenge isn't just the model, but making everything work together at scale. If the problem is hard, that's where I do my best work. Over the years I have architected and delivered full-cycle AI systems covering deep learning, LLMs, computer vision, NLP, MLOps infrastructure, and cloud-native deployments. I don't just build models — I build systems that work reliably at scale. I am the right fit if your project involves a complex AI system that needs to be built right, not just fast, multiple moving parts such as data pipelines, model training, APIs, and deployment that need to work together seamlessly, a challenging problem where off-the-shelf solutions fall short, or long-term thinking around performance, cost, and maintainability. My core expertise spans deep learning and LLMs including transformer models, BERT/GPT fine-tuning, and RAG pipelines using PyTorch, TensorFlow, and JAX. I work extensively in computer vision with YOLO, R-CNN, and Vision Transformers, as well as NLP, semantic search, and conversational AI powered by vector databases like Pinecone and Milvus. On the infrastructure side, I build end-to-end MLOps pipelines using Kubeflow, MLflow, and DVC, with CI/CD for models via GitHub Actions and GitLab, and monitoring through Prometheus and Grafana. I deploy across AWS SageMaker, Azure ML, and Google Vertex AI using Docker and Kubernetes, with a strong focus on cost-optimized GPU and TPU workloads. I also have deep experience in data engineering with ETL pipelines, feature stores, real-time streaming using Spark and Flink, and warehousing on Snowflake and BigQuery. For AI-powered APIs and SaaS products, I work with FastAPI, Node.js, Redis, PostgreSQL, and MongoDB. Additional expertise includes reinforcement learning, diffusion models, GANs, federated learning, model quantization, edge AI with TensorFlow Lite and CoreML, and AI explainability using SHAP and LIME. I bring strong communication, clean documentation, and a consistent track record of delivering complex AI projects on time. If you have a challenging end-to-end AI project, I would love to hear about it.

🧭 **I design and build agentic systems that survive production — observable, evaluable, and maintainable by your team after I leave.** 🏅 **Expert-Vetted | 100 % Job Success | Physics PhD, $90K+ earned. Recent: VIVIA (real-estate multi-agent platform, WhatsApp + voice + CRM) and a Neo4j-backed RAG pipeline rated ★5.0 Agents fail where teams don't look: prompt fragility, silent regressions, untraced failures, no fallback paths. That's the first thing I plan for. 🏗️ **Architectural scope I cover** - Multi-agent orchestration with LangGraph — explicit state machines, checkpointing, human-in-the-loop - GraphRAG on Neo4j — entity resolution, hybrid retrieval, explainable reasoning paths - Agent evals & observability — LangSmith / custom tracing, regression suites, cost dashboards - Production deploys — vLLM / Docker / Kubernetes, load-balanced inference, fallbacks across providers - Integration layer — WhatsApp, Twilio voice, CRM APIs, MCP servers, webhook resilience 🔬 **Background** PhD in Physics + years as a quantitative researcher. I treat agent behavior as a measurable system — I run experiments, log everything, and challenge claims that don't come with numbers. ✅ **Recent work** - **VIVIA** — Multi-agent real-estate platform: channel-agnostic core, per-agency scoping, lead follow-up sync, voice calls, CRM integration. Led modular refactor from monolith to clean separation of concerns. - **LLM/VLM fine-tuning & deployment** — custom load-balanced GPU platform, $10K+, ★5.0. - **AI Compliance system** — LLM guardrails, evaluation harness, and audit trail for regulated-industry workflows (i.e., full traceability). - **Neo4j calendar-event ingester** — production graph pipeline, ★5.0. 🛠️ **Stack** LangGraph · LangChain · LlamaIndex · Neo4j · Qdrant/Pinecone · Supabase · vLLM · FastAPI · Python/Cython/C++ · Docker · Twilio · MCP · WhatsApp/Notion SDKs If you're scoping an agent or RAG system and want someone who'll push back on the architecture before writing code — **let's talk.** 📬

I'm an AI engineer with 7 years of production experience at Microsoft Copilot and IBM, plus a Master's in AI and Data Science. I specialize in building agentic AI systems—intelligent, autonomous workflows that reason, act, and deliver measurable business outcomes. What most teams miss: AI isn't about the LLM, it's about orchestration. I design and deploy multi-agent systems using LangGraph, AutoGen, and production frameworks where AI agents collaborate with deterministic logic and human oversight to solve complex, high-stakes problems. I build systems that work, not demos that impress. EXPERTISE AGENTIC AI AND MULTI-AGENT SYSTEMS - Multi-agent orchestration (LangGraph, AutoGen, Crew.ai) - Agent design: perception, reasoning, action loops - State machines and supervisory control - Human-in-the-loop AI workflows - Agent-to-agent communication and collaboration - Real-time monitoring and agent auditing LARGE LANGUAGE MODELS AND LLM ENGINEERING - Prompt engineering and few-shot learning - Structured outputs (JSON schemas, Pydantic validation) - Function calling and tool use - Long-context reasoning (200+ page document analysis) - Fine-tuning and adaptation - Cost optimization and latency reduction - Multimodal LLMs (text + vision) RETRIEVAL-AUGMENTED GENERATION (RAG) AT SCALE - Hybrid vector + keyword indexing (Weaviate, Qdrant, Pinecone) - Query routing and intelligent retrieval - Chunk optimization and reranking - Context compression - Citation and source tracking - Conflict detection across document sets - Production RAG pipelines (reducing hallucination) PRODUCTION AI ARCHITECTURE - API-first design (FastAPI, serverless) - Microservices and distributed agent systems - Async processing and queue management - Model deployment and inference optimization - Monitoring, observability, logging - Graceful degradation and fallback strategies - Security and governance in regulated environments MACHINE LEARNING AND DATA SCIENCE - Supervised and unsupervised learning (XGBoost, Random Forest, ensemble methods) - Deep learning (CNN, RNN, Transformers, TensorFlow, PyTorch) - NLP pipelines (tokenization, embeddings, semantic search) - Statistical analysis and hypothesis testing - Data visualization and reporting WHAT I BUILD INTELLIGENT AGENTS AND CHATBOTS Agentic chatbots that reason through multi-step problems, retrieve relevant context, and execute actions. Customer support, technical assistance, content generation, decision support. DOCUMENT INTELLIGENCE SYSTEMS Multi-agent workflows that ingest complex document sets, extract structured information, detect conflicts, generate RFIs, build takeoffs, and produce cost estimates. Built for real-world accuracy, not demos. AUTONOMOUS WORKFLOWS AI agents that coordinate across business processes: data pipeline orchestration, content generation at scale, financial analysis, project management, research and analysis. RAG-POWERED ANALYTICS Question-answering systems over your proprietary data (documents, databases, knowledge bases) with source attribution, confidence scoring, and multi-turn reasoning. CUSTOM AI SOLUTIONS Tailored agentic systems for your specific workflow—whether that's construction estimating, contract review, healthcare intake, anomaly detection, or predictive analysis. TECHNICAL STACK Frameworks and Orchestration: LangGraph, AutoGen, Crew.ai, LangChain, LlamaIndex LLM Providers: OpenAI (GPT-4, GPT-4o), Anthropic Claude, open-source (Llama, Mistral) Vector Databases: Weaviate, Qdrant, Pinecone, Chroma Backend and Deployment: Python, FastAPI, Docker, AWS (SageMaker, Lambda, S3), serverless ML Frameworks: TensorFlow, PyTorch, scikit-learn, XGBoost Data and Databases: SQL, PostgreSQL, MongoDB, BigQuery Monitoring and Observability: LangSmith, custom logging, performance tracking INDUSTRIES AND IMPACT Enterprise SaaS | Financial Services | Healthcare and Biotech | Construction and AEC | Legal Tech | Government and Defense | Consulting | E-commerce | Nonprofits --- HOW I WORK Discovery First — 20-minute conversation to understand your problem, timeline, and success metrics. No fluff, just clarity. Phased Delivery — Start with an MVP that proves value. Expand from there. You control scope at each phase. Production-Grade from Day One — Every system is built to scale, monitor, and evolve. Not a prototype. Transparent and Collaborative — Regular updates, explainable decisions, alignment on progress. I work with your timezone. Honest Assessment — Sometimes the answer isn't "build an AI agent." I'll tell you if a simpler solution fits better. LET'S TALK Whether you're exploring agentic AI for the first time or optimizing an existing system, let's have a conversation. Message me or schedule a consultation. I'm here to turn your business challenge into an intelligent, auto
