Hi there! I'm Nikolaos Sourlos

Software Engineer · LLMs

Software Engineer at TU Delft bridging applied research and engineering. I build LLM-driven evaluation systems, stitch together RAG pipelines and tools, and orchestrate GPU infrastructure so that LLMs can be evaluated, optimized, and deployed with confidence.

About Me

Software Engineer at TU Delft with a focus on LLMs.

My core work centres on benchmarking and evaluating LLMs on Q&A tasks, building prompt-driven agent systems, integrating LangSmith, and providing reproducible evaluation metrics across providers such as OpenAI, Anthropic, Gemini, HuggingFace, Together, and Groq. I enjoy the challenge of turning raw research prototypes into reproducible systems that researchers can rely on. I also led initiaves to compare GPU providers for on-demand rentals, to upgrade GPU infrastructure of the university.

Previously, I pursued a PhD project on validating AI lung nodule detection software, assessing sources of bias, and collaborating with interdisciplinary teams. My background in Physics and Biomedical Engineering means I approach problems with both theoretical rigor and an applied engineering mindset.

I also run a sole proprietorship company, using Python/Flask on the backend and HTML/CSS/Tailwind on the frontend. I’m passionate about LLMs, deepfakes, stable diffusion, computer vision, and everything that automates the boring parts of everyday development work.
