Building intelligent agents & RAG systems

MSc Artificial Intelligence @ BTU Cottbus. I design LLM agents, RAG pipelines, and fine-tuned models โ€” turning research into production-grade AI.

// ABOUT

Who I am

I'm Vidyashree โ€” an MSc AI student at Brandenburg University of Technology, focused on LLM agents, RAG architecture, and fine-tuning.

My current work centers on bringing language models into industrial control โ€” using LoRA/QLoRA-adapted Llama 3.2 to make hydraulic process systems adaptive and natural-language driven.

I believe in "true speed is predictable, secure, and reliable execution" โ€” production-grade AI that works, not just demos.

What I'm currently building

๐Ÿ”ฌ MASTER'S THESIS ยท IN PROGRESS

LLM-Based Control of Festo Fluid Process Systems

Replacing rule-based PID and C++ HTTP control logic with adaptive AI decision-making. Fine-tuned Llama 3.2 3B Instruct with LoRA/QLoRA on hybrid real + physics-informed simulated data (20 sensor variables, 5s sampling). Closed-loop evaluation on level + temperature control.
