Ph.D. data scientist, 10+ years applied ML, Top Rated on Upwork with 4,000+ hours. My recent work is LLM agents in production. Reliability problems that only surface after deployment, where data science depth matters more than most expect. My background started in quantitative work: forecasting, trading systems, time series, probabilistic models. That shapes how I think about AI systems. I know the failure modes that show up after you deploy, and I know what "reliable enough" means for a given problem. Not just in theory. What I work on now: AI agents and multi-agent systems. Reasoning pipelines, orchestration, tool calling, human-in-the-loop controls. The hard part is at the boundary: where the LLM reasons, where deterministic code takes over, and what happens when the model is confidently wrong. RAG and document intelligence. Hybrid retrieval, reranking, citation tracing. Systems where every answer needs to be source-traceable, because "probably correct" was not good enough. Python backends with FastAPI on AWS, GCP, and Azure. The layer connecting AI to the rest of the product. LLM integration and evaluation: Claude, OpenAI, open-weight models. Structured outputs, function calling, eval pipelines. I have also reviewed production code for LLM training pipelines, so I have seen model behavior across thousands of real inputs I did not design. I work best with clients who have a specific, real problem and want a system their team can maintain. Stack: Python, FastAPI, Claude API, OpenAI API, LangChain/LangGraph, pgvector/Pinecone/Qdrant, PostgreSQL, Docker, AWS/GCP/Azure.

Most businesses are sitting on valuable data, they just don't know how to use it yet. I help founders, managers, and growing businesses turn that data into clear decisions, accurate predictions, and real results. I work with businesses to solve practical problems using data: forecasting outcomes, understanding customer behavior, automating repetitive analysis, and building intelligent systems that save time and reduce guesswork. - Turning messy, overwhelming data into clear, actionable insights - Building prediction models with 87%+ accuracy that help you plan ahead with confidence - Automating manual reporting and analysis to save your team hours - Identifying patterns in customer data to support smarter business decisions - Delivering results you can actually act on, not just technical reports A few things I'm proud of: - โญ 100% Job Success Score across all completed projects on Upwork - ๐ŸŽฏ Built prediction models achieving 87% accuracy on real-world data - โœ… 5-star reviews on every completed client engagement across multiple platforms - ๐Ÿ“Š Delivered solutions across healthcare, education, and business analytics I focus on practical solutions, not just theory. Every project I take on is built around your specific business goals and designed to fit into how your team already works, no unnecessary complexity, just results. If you're ready to make your data work for you, I'd love to hear about your project. Let's talk.
