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. 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

Once an Astrophysics Researcher, now a 3× AI Founder. I turned curiosity about the universe into AI systems that drive measurable business outcomes.

Most AI and SaaS MVPs fail in three places: they ship too slow to validate the idea, they break the moment real users hit them, or they're built on architecture that won't scale past 10K users without a rebuild. I'm a full stack developer and Claude Certified AI specialist who builds production-grade AI agents, agentic systems, automations, SaaS platforms, and mobile apps that don't have those problems, and I have receipts. Facebloom (AI + ML mobile): Single-image facial analysis app with structure, symmetry, expressions, celebrity look-alike matching, and friend-vs-friend face comparisons. Shipped an influencer dashboard with affiliate tracking that pushed the app to Top 20 on the App Store. TopTec (Full-stack SaaS + AI voice agent): Multi-tenant home services platform with role-based dashboards, Stripe subscription lifecycle, an admin panel, and an AI voice receptionist (Twilio + VAPI + GPT + MCP) wired into n8n automation pipelines that close bookings 24/7. Fotivo (AI web app): Gemini-powered visual creation platform for ecommerce brands. AI orchestration engine, Stripe billing, rate limiting, admin dashboard. SMFmed (Healthcare SaaS): AI-powered medical records platform with AI-generated report insights, OCR/PDF parsing, and a secure doctor portal with role-based access for patients, doctors, and admins. BUFF (Flutter mobile): Gamified fitness app for the Buff Dudes brand (1M+ YouTube subs). 50,000+ users in year one, 5-6K daily active, RevenueCat subscriptions, scalable Node.js backend. ✅ How I work: I scope the MVP to what actually proves the thesis, not a feature dump. I architect for v2 from day one (auth, billing, multi-tenant boundaries, REST APIs, webhook lifecycle) so you don't rebuild after the first 1,000 users. I integrate AI agents and automations where they earn their weight: orchestration, structured outputs, voice agents, n8n workflows, never as a bolt-on. I also take over and fix existing builds: debugging live SaaS platforms, stabilizing buggy mobile apps, and resolving API and backend issues fast. ✅ What I build: Full Stack web apps and AI agent systems (OpenAI, Gemini, Claude, ElevenLabs, VAPI, Twilio), SaaS platforms with Stripe billing, multi-tenant architecture, admin panels and dashboards, backend and API development (Node.js, Express, Python, REST APIs, webhooks), mobile apps in Flutter (iOS + Android), n8n and CRM automation workflows, bug fixes, debugging and stabilization of live web and mobile products, full-scale production systems when the MVP starts working. ✅ Stack: - Frontend and Mobile: React, Next.js, Flutter, TypeScript, JavaScript - Backend: Node.js, Express, MERN Stack, Python, FastAPI, Firebase, REST APIs, Webhooks - AI and Agents: OpenAI, Gemini, Claude, LangChain, RAG, LLMs, Multimodal Models - Agentic AI and Voice AI: Twilio, VAPI, ElevenLabs, Retell AI - Automation: n8n, Zapier, CRM and workflow automation - Machine Learning: PyTorch, TensorFlow, ML Kit, NLP, Neural Networks, Computer Vision (Mediapipe) - Database: PostgreSQL, Supabase, MongoDB, MySQL, DynamoDB - DevOps: AWS, Vercel, GitHub, CI/CD Pipelines, Serverless - Payments: Stripe, RevenueCat, Plaid If you're shipping an AI product or SaaS MVP, building out a full stack web or mobile app, or need an existing build fixed and scaled past launch, send me the brief. I'll tell you honestly if I'm the right fit before we waste each other's time.

Building AI Products That Deliver Business Outcomes, Not Just AI Features. Businesses don't invest in AI because they need another chatbot. They invest in AI to eliminate manual work, accelerate operations, improve customer experiences, and unlock new revenue opportunities. The challenge isn't integrating an LLM, it's engineering an AI system that is secure, scalable, reliable, and ready for production. I help startups, SaaS companies, and enterprise teams design, build, and scale AI-powered Products that become a core part of their business. My expertise spans AI Agents, Agentic AI, Workflow Automation, LLM Applications, AI SaaS Platforms, Enterprise AI, AI Integrations, and Retrieval-Augmented Generation (RAG), with a strong focus on production architecture and long-term maintainability. From solution architecture and technical discovery to deployment, monitoring, and optimization, I work across the complete AI development lifecycle. Every system is designed with scalability, observability, security, performance, and cost efficiency in mind.

Whether you're building an AI-native product, integrating AI into an existing application, or automating complex business workflows, I bring the technical depth, product thinking, and Architectural experience needed to deliver production-ready solutions

I build production-grade AI products for health and fitness companies. LLM/RAG, FastAPI, React, Flutter. Idea, or a broken MVP, to a real product that holds up. If you validated an idea and now need it built right, or you've got a vibe-coded MVP that's breaking and can't scale, that's exactly what I do. I take health and fitness AI products from concept to launch, the kind real users actually use every day. What I've shipped, all architected and built by me end to end: CuePilates, a full AI SaaS on Next.js, Supabase, Stripe and OpenAI, idea to launch in under a month. A clinical AI platform doctors use daily. DietTalk, live on the App Store and Google Play. How I work: a free call to scope it, then a working prototype of your core feature in about 2 weeks that you can use yourself, then the full build in phases where you see working software and approve each phase before you pay for it. Weekly demos, daily comms, clean handover so you own it. Secure, encrypted data handling, with production standards baked in: auth, payments, multi-tenant, scale. Not a demo that falls over at launch. If you're tired of cheap builds that leave you stuck, let's talk.
