AI Developer | Automation & Predictive Analytics I build AI systems that take repetitive work off your plate and turn your data into decisions you can act on. Over 5+ years I've automated workflows that ran for hours down to minutes, shipped computer-vision models north of 97.5% accuracy in production, and built specialized models that outperform frontier LLMs on-task at a tiny fraction of the compute. AUTOMATION I design pipelines and AI-driven workflows that replace manual, error-prone processes: LLM-powered document processing, data ingestion and ETL, RAG/MCP integrations, and agentic systems that handle the busywork. I've cut enough of it for clients to gain multiples worth of efficiency gains. PREDICTIVE ANALYTICS I build forecasting, classification, and risk/scoring models that turn historical data into reliable signal - with the feature engineering, evaluation, and monitoring to keep them accurate in production, not just in a notebook. I also handle the engineering around the models - infrastructure, security, and the supporting services that keep everything running in production. When a project calls for it, I work across NLP, computer vision, and custom model training/fine-tuning. SELECTED RESULTS - Automated document processing from hours to minutes with LLMs - 97.5%+ accuracy on production computer-vision inference - Fine-tuned a compact language model to more than 5x the on-task accuracy of a frontier LLM (GPT-5.5) while using thousands of times less compute CORE SKILLS - Predictive analytics & forecasting, machine learning, deep learning, LLMs, computer vision - Workflow & data automation, MLOps, custom model training, optimization & fine-tuning - Supervised, unsupervised (K-Means, HDBSCAN), and reinforcement learning (Stable-Baselines3) STACK - Languages: Python, SQL, Bash - ML/Data: scikit-learn, PyTorch, TensorFlow, XGBoost/LightGBM/CatBoost, pandas - Build & Deploy: FastAPI/Flask, Docker, Kubernetes, Git I care about modular, efficient systems that keep working long after handoff - not one-off scripts that break the moment requirements shift. If you've got a process worth automating or data worth predicting from, let's talk about moving your project forward.

Custom AI Agents, RAG Pipelines, & Intelligent Workflow Automation Are you looking to: - Eliminate repetitive manual tasks and cut operational costs? - Build a cutting-edge AI product or scale a SaaS MVP? - Integrate LLMs directly into your existing business software? Most clients come to me with the same problem: a powerful LLM idea but no reliable Python backend to ship it. That is exactly where I help. I design clean, scalable Python systems, wire them into LangChain with full LangChain agent support, LangChain tool calling, LangChain memory, and LangChain Expression Language — then ground every LLM response in your data through a well-tuned RAG retrieval layer so answers stay accurate instead of hallucinated. Core Technical Expertise: Generative AI and LLM Systems: OpenAI API, Anthropic, Llama, LangChain, LlamaIndex, LLM prompt design, LLM call logging, and LLM cost optimization AI Architecture: RAG (Retrieval-Augmented Generation), Autonomous AI Agents, Agentic AI workflows, and Vector Databases including Pinecone, ChromaDB, and Milvus Python Backend and APIs: FastAPI, Flask, REST APIs, Webhooks, and custom Python integrations Data and Workflow Automation: Web scraping with BeautifulSoup, Selenium, and Scrapy; workflow automation with Celery, Zapier, Make, and Crontabs Cloud and DevOps: Docker, AWS, GitHub Actions, PostgreSQL, and MongoDB What I Can Build With Python, LLM, RAG, and LangChain: Autonomous AI Agents — custom LangChain agents that reason, use tools, browse the web, and execute multi-step Python workflows without constant supervision.

If your data is stuck in the wrong system, in messy files, or behind an awkward API, I can help. I turn complex data problems into working systems and usable deliverables. I help clients move data between platforms, automate manual work, clean up unreliable exports, and build workflows that save time and reduce errors. Whether the deliverable is a program they can keep using, or a clean CSV, Excel file, report, or database, I can make it happen. Most of my work is API integrations, ETL pipelines, backend automation, data processing, and data migrations. I'm at my best when the problem is not clean or perfectly defined. I'll solve that problem first. I build data workflows that are meant to hold up in real use. I work with complex APIs, big JSON or XML data files, elaborate schema, folders full of CSV and Excel files, and large datasets where correctness matters. The result is a cleaner dataset, a dependable program, or a responsive and well-designed workflow. If you need a dependable program, a solid new system, or a clean final dataset, I can help.
