I have two specialties: Geospatial data engineering and computational design. I am a digital artist specializing in computational design in C# and Grasshopper for sculpture and jewelry. I design at sub-millimeter tolerances for additive manufacture. My jewelry has been featured in magazines including Elle, Cosmopolitan and others. As an ecommerce developer, I have built ecommerce pipelines that generate geometry, create digital assets and renders, and upload them to Shopify via API. My background in urban planning, architecture, real estate development, and fine art complements my technical skills. I alsowork as a data engineer for at a notable municipal office, focusing on geospatial data engineering, vehicle routing, and fleet management on the Databricks Lakehouse, PowerBI, and Airtable, applying my knowledge of geometry in two dimensions. My Experience: 8 years as a software developer for The City of New York. Current title: Senior Data Solutions Advisor.

I help businesses automate lead generation, follow-ups, and internal workflows using AI and tools like Zapier, n8n, and APIs. Recently, I built: • An AI workflow system that automates data processing and reduces manual work • A hospital management system using LLMs and FastAPI • Automated dashboards for business insights I focus on building simple, reliable systems that save time and scale operations. I’m happy to start with a small test task to prove my work.

I'm an Upwork Expert-Vetted Data Scientist who covers what usually takes two specialists: classic ML and modern LLM systems, shipped to production. Nobody understands your business like you do, and you know exactly the bottleneck you want gone. You want someone who can see it just as clearly, bring it to life the way you imagined, and build it to last. That has been my track record. Imagine handing off your idea, and what comes back makes you say, "This is exactly what I had in mind!" That is the feedback I hear most from my clients. Here's what working together looks like: You explain the vision once. I turn it into a clear plan, build the system end-to-end, and ship something your team can actually run and trust. Whether it's an LLM or RAG application, an AI agent, or a forecasting or anomaly-detection engine, it is handed over to you already deployed in production, documented, and yours to keep building on. What my clients say: → "She took our vision as her own and brought it to life." → "When she says she'll handle something, it's done." → "Hwei is the proverbial needle in a haystack. She gets it. She gets it done." Recent projects: • A US women's health startup: I led the AI intelligence layer at the core of their v1.0, live before their funding raise. • A Fortune 500 consumer brand: I built a stability testing platform that turned days of manual work into seconds. • An Italian telecom compliance consultancy: I built an LLM document-processing pipeline that cut review time from days to minutes, with zero false approvals. • A Dutch water consortium: I built an anomaly-detection dashboard that flagged genuine contamination events with zero false alarms. → Expert-Vetted · Top 1% on Upwork · 100% Job Success → ML and AI since 2018 · 8 published papers · trained at Fraunhofer SCAI and the University of Hamburg Tell me what you're trying to build, and I'll reply with a clear path forward, built around your goals. ================== Tools and capabilities: • Generative AI and LLMs: large language models, RAG (Retrieval Augmented Generation), AI agents and multi-agent systems, chatbots, prompt engineering, LLM evaluation, vector databases (ChromaDB), LangChain, Pydantic AI • Machine learning: predictive modeling, anomaly detection, time series forecasting, predictive maintenance, statistical analysis, deep learning, computer vision, natural language processing (NLP) • Engineering and delivery: Python, FastAPI, Docker, cloud deployment (AWS, Azure, Render), data analysis, data pipelines, interactive dashboards (R Shiny, Streamlit, Gradio), data visualization • Model APIs: OpenAI, Anthropic Claude, Google Gemini, Hugging Face • Consulting: artificial intelligence (AI) strategy, AI implementation, AI consulting, code audits, knowledge transfer
