Building intelligent agents & RAG systems

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

Who I am

I'm Vidyashree, 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, 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". Production-grade AI that works, not just demos.

What I'm currently building

🔬 MASTER'S THESIS · 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.

Pharma Clinical Trials Agent

Pharma analysts waste hours manually tracking competitor trial activity across public registries. This pipeline fetches live clinical trial data via public APIs (using ClinicalTrials.gov as the data source), runs it through Gemini AI to extract structured intelligence including phase, purpose, geography and organization, and surfaces it in a filterable dashboard. Analysts can instantly see where competitors are running trials, whether markets are still exploring (observational) or validating (interventional), and which geographies are heating up. Being evolved into an autonomous multi-agent monitoring system. See the live demo below.

My AI journey

JUL 2026

JUNI x Tesla Gigathon — 3rd Place

My first hackathon. Worked with a cross-functional team (product, manufacturing, supply chain) at Giga Berlin, building data logic to flag material reorder needs based on lead time and coverage, showcased via a Streamlit app. Team secured 3rd place.
