I built and operate FTIR.fun, a live AI-assisted FTIR spectral analysis platform serving paying users in 40+ countries. As its sole developer and domain architect, I combine spectroscopy, software engineering, and scientific writing in one production service.

I designed its tri-axis retrieval engine across 130,000+ reference spectra, including custom peak detection, baseline correction, interference-aware matching, knowledge graphs, and RAG/LLM workflows. I also developed Django and FastAPI backends, instrument-format parsers, public MCP/REST APIs, payment integration, and a 50+ language pipeline.

Before FTIR.fun, I led formulation analysis and unknown-sample characterization projects at Guangzhou Jingxi Testing Service Co., Ltd. for polymers, coatings, adhesives, pharmaceuticals, and cosmetics. I use FTIR alongside chromatography, mass spectrometry, thermal analysis, and literature research to resolve complex composition questions.

I also provide technical manuscript editing and scientific writing for polymer science, analytical chemistry, spectroscopy, and materials characterization. My work includes response-to-reviewers drafting, figure review, submission-package preparation, and publication-ready editing in English.
