Eren Keleş

AI Developer & Automation Engineer

I build AI systems that ship — from a 20,000-line platform serving 50+ teachers to published research. Currently seeking an Erasmus+ traineeship in Europe.

AI Educational Platform

BilChat

20,000+ LOC · ~50 teachers · ~60% less prep time

I was the only developer on this one. BilFen Schools wanted teachers to create curriculum-aligned content with AI, so I built the whole thing — a RAG pipeline that actually understands Turkey's K-12 curriculum, a homework scanner that handles ~300 assignments a week, and a live quiz game that 15+ classrooms started using on their own. Went from idea to production in about 3 months.

RAG Pipeline Evaluation

IEEE Conference Paper

RAG Pipeline Evaluation

86.2 F1 · 0.77% hallucination · 13ms latency

My capstone project turned into a proper research paper. I tested three different RAG setups to see which one actually works best for educational chatbots — comparing accuracy, speed, and how often they hallucinate. The best config hit 86.2 F1 with under 1% hallucination. Got accepted at an IEEE conference and presented it.

VS Code Extension · "Stop clicking Accept."

YoloMode

3,800+ downloads · 5-star · v3.1.1

I got tired of clicking 'Accept' on every single AI suggestion while coding, so I built a VS Code extension that does it for me. It hooks into Antigravity IDE and Agent Manager through Chrome DevTools Protocol and auto-accepts agent steps, terminal commands, and code edits. Turns out other people were annoyed by the same thing — 3,800+ downloads and counting.

Agentic AI System

Email Outreach Automation

1,500+ emails/wk · 11% response · ~2% spam

Needed to reach a lot of companies for a university sponsorship campaign, so I built an AI-powered outreach system. Claude Code writes the emails, Google Apps Script handles the sending, and the whole thing tracks opens, replies, and auto-sends follow-ups. It ended up landing actual sponsorship deals — not bad for a side project.

Freelance Client Project

WellWorks Turkey

23-page SPA · ~70% faster dev

A freelance gig for a dual-brand pharmacy chain. They needed a full website with store locator, SEO-friendly pages, and content management. I used Claude Code for most of the development, which cut the timeline down significantly. The client was happy, the site ranks well, and it proved to me that AI-augmented dev is the way to go.

Nov 2025 — Feb 2026

Software Developer

BilFen Schools · Istanbul

Hired as the sole developer to build their AI platform from scratch. Designed and shipped BilChat — a full-stack system with RAG, multi-agent AI, and real-time features. Teachers actually use it daily, which is the part I'm most proud of.

Education

Mar 2025 — Aug 2025

Erasmus+ Exchange Semester

Hochschule Karlsruhe (HKA) · Germany

Spent a semester in Karlsruhe through Erasmus+. Took courses in Machine Learning, Agile Project Management, and AI applications. Also picked up some German along the way. Living abroad and studying in a different academic system was a great experience — it pushed me to be more independent.

B.Sc. Computer Engineering

Istanbul Kültür University

Where it all started. Focused on AI and software engineering in my later years. My capstone project — evaluating RAG pipeline architectures — turned into an IEEE conference paper, which I didn't expect. Advised by Prof. Dr. Akhan Akbulut, who was a big help throughout.
