John Treen

I’m a self-taught AI Engineer and Full-Stack Software Developer who builds machine learning applications, AI-powered tools, REST APIs, and modern web applications. I focus on turning NLP and semantic search ideas into working products people can use confidently.

I created RecruitFlow AI Elite, an end-to-end AI recruiting platform featuring ATS scoring, semantic matching, resume parsing, and AI-powered recommendations. I built the system end-to-end—FastAPI backend APIs and React/TypeScript frontend—then implemented semantic similarity scoring using Sentence Transformers.

In the platform, I also added PDF, DOCX, and TXT resume parsing capabilities and built AI recommendation and candidate scoring systems. I Dockerized and deployed the applications using Render and Vercel, so the solution runs reliably in real-world environments.

Since 2023, as an Independent Software Engineer | Remote, I design and develop AI-powered applications using Python, FastAPI, React, and TypeScript. I build machine learning and NLP-powered tools for resume analysis and semantic search, and I deploy and maintain production-ready cloud applications. I’m currently strengthening my foundations through the Boot.dev – Computer Science Program.
