I evaluate Turkish LLM and voice AI outputs to improve accuracy, safety, and localization.
What I'm looking for
At Gini Talent for Yandex, I evaluated and ranked Turkish LLM search outputs, optimized text within RLHF workflows, and stress-tested model guardrails through adversarial prompts. I maintained approximately 90% QA accuracy while delivering high-volume work under strict turnaround times.
At RWS Group, I curated Turkish speech and audio-text datasets for ASR and TTS models, comparing synthetic voice outputs for naturalness, prosody, and pronunciation. I identify acoustic, phonetic, and semantic discrepancies that affect localized AI quality.
I also teach Turkish and bring advanced historical research, multilingual analysis, and cultural context to complex language, safety, and alignment challenges.
