I build LLM data pipelines, forecasting models, and production APIs for founders and small teams. From one-time analysis to product-grade systems. I co-founded a market-data startup, where I built an NLP pipeline that labels 1.5M+ news articles and shipped a production API. My research on LLM rerankers was accepted at SIGIR 2026, a leading conference for search and ranking systems. I also maintain open-source LLM tools, including a LangGraph agent CLI on PyPI and a local RAG tool with page-cited answers. I have a strong track record in: • LLM data pipelines: classification, labeling, sentiment scoring, and extraction • Production ML systems and APIs (FastAPI, Docker, AWS, Google Cloud, BigQuery) • Forecasting models for sales optimization and budget planning • Dashboards and decision tools • CRM data analysis (HubSpot, Zoho) • RAG systems and LLM agents (LangGraph), with testing and evaluation Founders and team leads typically work with me to: • Replace manual labeling, tagging, or reporting work with automated LLM pipelines • Add an AI feature to an existing product and make it reliable enough to ship • Build forecasting models on transaction, sales, or CRM data • Extract insights from complex data such as transactions, call records, and multi-source attributions • Turn an LLM prototype into a tested, deployed system I have 3+ years of freelance experience and 5+ years of hands-on data science and analytics. I've worked directly with founders and small teams, and delivered 40+ projects with a 100% success rate. I hold a Master's in Computer Science and a bachelor's degree in business, and I conduct applied research in machine learning for finance and NLP. What previous clients say: "Baris will always be the #1 choice in his category. Great guy. 10/10." "One of the best freelancers I've worked with. He understood quickly what I was trying to build." For larger projects, my usual structure is a short paid discovery to map the problem and the data, then a fixed-price build with clear milestones, so the budget is known before the work starts. Ongoing support is optional after that. If you have an LLM or data problem that needs to work reliably in production, feel free to send a message. I'll be happy to take a look.
