𝐇𝐢, 𝐈'𝐦 𝐋𝐞𝐞 𝐁𝐞𝐧𝐧𝐞𝐭𝐭, a Principal AI/ML Engineer and full-stack systems builder with 15+ years shipping production AI platforms, not just prototypes. I lead engineering teams with a bias toward production, clear architecture, measurable outcomes, and systems built to be relied on. I've driven modernizations that delivered $300K+ in annual savings, architected IoT platforms that secured $1M+ in funding, and co-founded a telecom SaaS still running nearly a decade later. Today, that same drive goes into SaaS products, cloud-native backends, and production AI, agents, multi-agent orchestration, RAG/knowledge systems, and LLM workflows (Claude/OpenAI/Azure) with MCP integrations. I build data pipelines, feature-ready datasets, and vector retrieval for reliable production ML, with evaluation and observability from day one. I move fastest where models, data infrastructure, and full-stack code must work as one system. 🚀 𝑷𝑹𝑶𝑽𝑬𝑵 𝑩𝑼𝑺𝑰𝑵𝑬𝑺𝑺 𝑰𝑴𝑷𝑨𝑪𝑻 • CommoditAg: $300K+ Annual Savings Modernized a legacy ag e-commerce platform (Shopify, React, ERP). Redesigned inventory/order data flows, automated reconciliation, and improved scalability. Delivered $300K+ annual savings and cleaner boundaries for analytics and AI/ML. • Smart Farm: $1M+ Funding & Acquisition Led product, data, and platform strategy from concept to release. Built device telemetry, cloud data models, and analytics pipelines. Helped secure $1M+ funding and supported growth through acquisition by Farmers Edge. • OpenRoadMobile: 10+ Years of Recurring Revenue Architected SaaS for cellular subscription automation, provisioning, commissions, billing, and reporting. Production data pipelines and orchestration still supporting operations a decade later. • iCommand: Enterprise Exclusivity Outcome Built a unified yacht/RV automation and telemetry platform (navigation, entertainment, environmental, vessel control). Edge-to-system integration and real-time workflows; helped secure Brunswick Boat Group exclusivity. • Saturn Partners: Production AI in Operations Shipped production LLM systems for content automation, RAG knowledge retrieval, and audience intelligence. Unified CRM/analytics data into context stores, cutting manual effort and improving campaign decisions. ⚙️ 𝑾𝑯𝑨𝑻 𝑰 𝑫𝑬𝑳𝑰𝑽𝑬𝑹 🔹 AI & Machine Learning Production LLM systems and agent platforms: multi-agent orchestration (LangChain/LangGraph, MCP), RAG/memory pipelines, prompt + eval systems, model routing, guardrails, and cost/latency control across OpenAI, Claude, Azure OpenAI, and AWS Bedrock. 🔹 Data, Analytics & Intelligence Data pipelines (ETL/ELT), context/feature stores, Databricks, CRM/ERP integrations, and decision workflows backed by operational analytics and AI-assisted insight generation. Dashboards and reporting with Power BI, Looker, and modern charting stacks for product and executive visibility. 🔹 Full-Stack AI Products End-to-end apps from concept to production: React/Next.js/Vue UIs, FastAPI/Node APIs, Postgres + vector search, queue workers, and SaaS backends (billing, auth, integrations), including platform modernization (Shopify + ERP). 🔹 Cloud, Enterprise & Edge Deploy and operate AI workloads on AWS, GCP, and Azure with Docker/Kubernetes, CI/CD, and observability. Edge-to-cloud telemetry (OpenWRT, GPS, device pipelines) for connected operations and hybrid automation. 🛠️ 𝑻𝑬𝑪𝑯 𝑺𝑻𝑨𝑪𝑲 🔹 AI/ML: Generative AI • LLMs • AI Agents • Multi-Agent Systems • LangChain • LangGraph • MCP • RAG • Embeddings • Vector Databases • pgvector • Pinecone • Weaviate • Hybrid Search • Reranking • Prompt Engineering • Tool Calling • Structured Outputs • Model Routing • Context Engineering • LLMOps • Guardrails • Evaluation Harnesses • AWS Bedrock • Azure OpenAI • Azure AI • OpenAI • Claude • Anthropic 🔹 Data & Visualization: ETL/ELT • Data Pipelines • Databricks • PostgreSQL • Redis • GraphQL • Feature Stores • Semantic Modeling • Operational Analytics • Power BI • Looker • Tableau • D3.js • Chart.js • Recharts • Apache Superset • Data Visualization • Business Intelligence 🔹 Full-Stack: Python • TypeScript • FastAPI • Node.js • React • Next.js • Vue • Astro • REST APIs • GraphQL APIs • Microservices • Event-Driven Architecture • BullMQ • SaaS • Shopify 🔹 Cloud/DevOps: AWS • GCP • Microsoft Azure • Docker • Kubernetes • CI/CD • Infrastructure as Code • Serverless • OpenTelemetry • Prometheus • Grafana • S3 • Observability 🔹 Edge/IoT: OpenWRT • GPS Telemetry • Edge Computing • Edge AI 🤝 𝑾𝑯𝒀 𝑾𝑶𝑹𝑲 𝑾𝑰𝑻𝑯 𝑴𝑬 I live by a simple rule: take ownership, stay in the hard parts, and finish what you start. If you’re looking for someone who will own the problem end to end and stay with it until it ships, let’s work together.
