Most AI tools don't know your business, they guess. I build RAG pipelines and LLM systems grounded in your actual data, so the answers your team gets are accurate, cited, and production-ready. I work with SaaS companies, professional services teams, and operations that are sitting on valuable documents, databases, and institutional knowledge their people cannot efficiently search or use. Whether that is thousands of PDFs, a knowledge base full of unstructured notes, a product manual, or internal documentation, I turn that data into something a language model can reason over reliably using retrieval augmented generation, semantic search, and vector embeddings. What separates my work from a generic ChatGPT wrapper is the engineering underneath. I architect the retrieval layer properly, with the embedding pipeline, chunking strategy, and hybrid search that decide whether a system stays accurate at scale, then connect it to vector databases like Pinecone, Chroma, Weaviate, Qdrant, or pgvector, tuned to your specific data. I use LangChain and LlamaIndex to assemble the system, and everything ships as a FastAPI backend, not a notebook. Here is the kind of work I have delivered. I have built RAG chatbots over large, messy document sets, including a system over a company's tax and financial documents where the team needed reliable answers they could trace back to the source. I have built private knowledge chatbots that let a business query its own internal documents in plain language, deployed both as web applications and on a client's own local system for privacy. I have built document intelligence pipelines that read and extract structured data from scanned documents and PDFs, using OCR together with vision capable models so the extraction holds up on real, imperfect files. My stack for LLM and RAG systems: - LLM APIs: Claude API (Anthropic) · OpenAI API · GPT-4o · Open-source models (LLaMA, Mistral) - Frameworks: LangChain · LlamaIndex · LangGraph · MCP Servers · Claude Code - Vector Databases: Pinecone · Chroma · Weaviate · Qdrant · pgvector - Backend: Python · FastAPI · REST APIs · PostgreSQL - Techniques: RAG Pipelines · Semantic Search · Embeddings · Prompt Engineering · Fine-tuning - Document Intelligence · Knowledge Base Architecture · Natural Language Processing What clients hire me for: • RAG pipeline builds over documents, databases, PDFs, and CRMs • Internal AI knowledge bases teams can query in plain language • Claude API and MCP server integrations for production AI applications • AI agent development with tool-calling, memory, and multi-step reasoning • LLM system audits for teams with a fragile or hallucinating prototype they need fixed If you have data and want AI that actually understands it, send me a message. Tell me what you're building and I'll tell you in plain terms what's possible and how long it takes. Retrieval Augmented Generation · RAG Pipeline · LangChain · LlamaIndex · LangGraph · Claude API · Anthropic · Claude Code · MCP Server · OpenAI API · Vector Database · Pinecone · Chroma · Weaviate · Qdrant · pgvector · Semantic Search · Embeddings · Prompt Engineering · Python · FastAPI · AI Agent Development · Knowledge Base · Document Intelligence · Natural Language Processing · Large Language Model · AI Chatbot · Machine Learning · Artificial Intelligence Let's get connected!

I help founders and growing businesses make better technology decisions before expensive mistakes slow growth. Most software projects do not fail because of bad code. They fail because goals were unclear, ownership was fuzzy, scope expanded without discipline, or early architecture decisions could not support real-world operations. My role is to reduce those risks early and help companies build systems that actually ship — and continue to perform as the business grows. I work with clients to clarify: • What they are truly trying to achieve • Where workflows, handoffs, or systems are breaking down • What should be built now vs. later • How to move forward within real budget, timeline, and operational constraints That starts with understanding the current business, processes, and data flows — then designing practical systems that are scalable, maintainable, and aligned to outcomes. Where it adds real leverage, that may include automation, integrations, or AI. ⸻ Experience & Approach I bring 30+ years of hands-on experience across healthcare, finance, legal, nonprofit, SaaS, and data-intensive environments. My background includes: • Software architecture • SaaS platform strategy • Backend systems and APIs • Systems integration • Workflow automation • AI-enabled business systems • Product and technical leadership I operate in a hands-on senior advisor model: • I personally lead architecture, technical assessments, planning, and key decisions • When execution support is needed, I can coordinate trusted developers under clear direction • You maintain one accountable senior point of contact throughout the engagement Clients get executive-level judgment where it matters most — without wasting senior budget on every implementation task. ⸻ How I Typically Work Successful projects usually follow a disciplined sequence: 1. Alignment – Clarify goals, risks, constraints, and success metrics 2. Solution Definition – Turn business needs into practical technical decisions 3. Architecture Review – Validate the direction before heavy investment 4. Phased Roadmap – Define milestones, sequencing, and priorities 5. Execution Support – Guide delivery, decisions, and course correction as needed This approach creates momentum, reduces rework, and leads to systems that last. ⸻ Clients Hire Me To • Serve as a Fractional CTO or senior technical advisor • Build MVPs and new SaaS platforms the right way • Rescue stalled or fragile software projects • Modernize legacy systems • Design automation and AI-assisted workflows • Integrate disconnected tools and data sources • Improve scalability, maintainability, and reliability • Get an unbiased view of build vs. refactor vs. replace ⸻ If you need someone to simply complete tickets, I may not be the best fit. If you want an experienced partner who thinks strategically, challenges assumptions, and helps you make sound technical decisions, we will likely work well together. I’d be glad to learn more about your project and discuss whether there’s a strong fit.
