🚀 Welcome to my Upwork Profile! 🚀 Do you have any questions about Android System? Do you want to extract data from a website? Message to me, I am very happy to talk to you whether you offer me a job or not. "If you have an apple and I have an apple and we exchange apples, then you and I will still each have one apple. But if you have an idea and I have an idea and we exchange ideas, then each of us will have two ideas." - George Bernard Shaw The services which I provided are as below: [ Android Development ] 🔸 8 years working experiences, developed multiple software for the company's smart devices. 🔸 Extensive experience in communicating with microcontrollers. 🔸 Experience with UI/UX design principles 🔸 Automated test code base on Appium [ Data Scraping] 🔸 utilizing cutting-edge techniques and tools to efficiently gather structured data from various online sources

I graduated from the University of Minnesota at Twin Cities with a Ph.D. in Thermal and Fluids (Mechanical Engineering). I have 7 journal publications and 4 patents, but I am mostly proud that I have helped over 70 clients over the past four years design and produce products, helping them make tens of millions of dollars. Having worked in a high-tech Fortune 500 company as well as in a manufacturing company as the chief engineer in the US, then leading Originex on product development and sourcing in China for 6 years, I am an expert in the following areas: • Sourcing from China and supply chain management and optimization • Consumer product development • Commercial systems and equipment design and engineering • Production automation system procurement • Amazon FBA Taking advantage of the depth of my technical skills and the rich experience I have gained over a broad range of projects, I help brands and companies in developed markets source and develop products and equipment cheaper, faster, and better out of China and other low-cost countries.

I build machine learning pipelines that actually work in production — not just notebooks that look good in demos. Most of my work revolves around tabular data: gradient boosting (LightGBM, XGBoost, CatBoost), tabular deep learning (TabNet, TabPFN), and causal inference. I've spent a lot of time on the unglamorous but critical parts — feature engineering, handling imbalanced datasets, model calibration, and making sure results are interpretable and reproducible. A few things I've shipped: A cancer risk prediction system for a medical research team (AUC > 0.84), with full feature importance analysis and threshold strategy reports. A 3D reconstruction pipeline based on Structure-from-Motion, robust enough to handle blurry and low-texture inputs. That work led to 2 software copyrights and a patent under review. A causal boosting framework (CBDT) for heterogeneous treatment effect estimation — benchmarked on IHDP, ACIC, and MIMIC-III. Paper currently under submission. Quantitative models for financial risk — credit scoring with XGBoost and TabNet, A/B testing on simulated datasets, ended up improving accuracy by 15% and cutting false positives by 20%. I'm comfortable working with financial data, backtesting pipelines, and building risk models from scratch. I also work with OpenClaw for robotic manipulation tasks and have experience integrating it into simulation and control workflows. On the tools side: Python is my daily driver, along with PyTorch, Transformers, Optuna, and Git. I write clean, documented code — not the kind you need to reverse-engineer to understand. I'm finishing up a B.Eng. in Software Engineering (Beijing University of Technology × UCD joint program, class of 2026). Kaggle Gold and Silver medalist. If any of this sounds relevant to what you're working on, drop me a message. I usually reply within a few hours.

I’ve worked at a top-tier security company, starting in malware incident response and reverse engineering. I specialize in rapid triage, forensic analysis, attribution, and complete eradication. After moving to the APT team, I focus on intelligence-led investigations, attack chain reconstruction, adversary/infra profiling, and detection engineering. My edge is “deep technical expertise + engineering delivery”: I perform low-level/malware RE and also build production-ready tools and automation in Go/C#/Python (including GUI utilities) to accelerate detection and response.
