Hey, I'm Eren. Full-stack Developer.

I like being there for the whole story of a product, from the first sketch to the release. If something itches at my curiosity, I take it apart first, and if it earns its place, I take it all the way to production. At Calibre Tour, I work on both the backend and the interface of a reservation and payment platform, with .NET, SQL Server, React, Next.js and Node.js. Outside work, I build LIBRAIN, an open-source multi-agent RAG system written in .NET 10. It ingests scientific papers, stores their embeddings in a vector database, and generates hypotheses that show their sources through a Reader → Synthesis → Evaluator flow. A Discovery Mode running in parallel looks for connections across 41 papers from AI, drug discovery, climate and neuroscience, and flags the speculative part separately as a novelClaim. I published its paper on Zenodo with a DOI. I spend most of my time on the backend side: how data flows, how services talk to each other, and keeping code readable months later. Those are the problems I like working on.

Software / Research Paper

LIBRAIN: A Multi-Agent RAG System for Scientific Discovery

2026 · Independent research · .NET 10 · RAG · multi-agent

An open-source, auditable multi-agent retrieval-augmented generation system for scientific hypothesis discovery, built end to end in .NET 10. A structural citation-validation contract drops any reference that does not resolve to the retrieved set, and a Discovery Mode fences the speculative part of each hypothesis into a separately scored novelClaim field. Every output is traceable by a correlation ID.

Research Project

Mobile Application for Hearing Impaired Communication

2021 · TUBITAK 2209-A · Unity3D · C# · speech-to-text
