What I'm looking for

I'm available now for remote work from North Cyprus (GMT+2/+3).

At Niyel Technologies Ltd., I built a bilingual Turkish-English system that maps customer needs to 746 NACE business-activity codes. I designed the evaluation harness first, using fixed test sets and statistical comparisons to decide which changes were ready to ship.

My experiments found that untuned BGE-m3 retrieval with logistic-regression heads outperformed LoRA fine-tuned LLMs in division-level classification. Adding a Qwen3-8B referee over the top 10 candidates raised first-answer accuracy on 877 short queries from 67.6% to 76.1%.

I also built a local RAG assistant for Red Dead Redemption 2 knowledge during the Microsoft AI Innovators Internship Program, with hybrid retrieval and calibrated refusal. I'm continuing the NACE system as a Volunteer Contributor at Niyel Technologies Ltd., and I'm completing a B.S. in Artificial Intelligence Engineering at Eastern Mediterranean University.
