Background

About me

I'm Vikou C Nelson, Full-Stack Developer | AI Builder | LLM Engineer with a PhD in Statistics & Econometrics. I work across AI/ML development, GPT engineering, and full-stack delivery — with a dual strength: mathematical rigor as a researcher and shipping applications ready for production.

I've built self-hosted LLM infrastructure (AetherGate), customer support agents (RAG + human escalation), Telegram conversational assistants, NeuroHelper tools, Tobit models validated against R, and reproducible AutoML pipelines with TPOT.

What drives me: turning your data and ideas into tools that save time, cut costs, and improve decisions. Every collaboration starts by understanding your business problem — not stacking buzzwords.
