Freelancer Overview

As a Loft 2.0 Annotator at Prosessor.AI Data & Language Services (Freelance, Remote – Türkiye) I contributed directly to high-quality AI/ML training data creation by performing precise audio-to-text transcription using the Loft 2.0 platform. Prosessor.AI specializes in integrating human expertise with machine intelligence to build accurate datasets for AI and machine learning projects, and my role focused on delivering clean, localized, and contextually accurate transcriptions essential for training robust speech recognition, NLP, and multilingual AI models. Key strengths include strong attention to detail in handling audio data, proficiency in transcription best practices to ensure high accuracy and consistency, and expertise in localization to adapt content across languages and cultural nuances. Additional skills in Localization, Annotation, Transcription, and Loft tooling set me apart in data preparation pipelines, where reliable human-in-the-loop annotation is critical for improving model performance in real-world AI applications. This hands-on experience in AI-adjacent data services equipped me to support scalable data labeling and quality assurance efforts for generative AI, voice AI, and language technologies.

As a Loft 2.0 Transcriber and Annotator at Prosessor.AI Data & Language Services (freelance, Türkiye), I performed high-precision audio-to-text transcription to create structured training datasets for AI and machine learning models. Using the Loft 2.0 platform, I processed conversations, interviews, and multilingual audio, delivering accurate timed transcripts with speaker identification, punctuation, and contextual notes as needed. The work supported large-scale datasets for speech recognition, NLP, and generative AI, often requiring localization for linguistic and cultural accuracy. I maintained >98% transcription accuracy per platform guidelines, followed detailed style guides, conducted self-reviews, and incorporated QA feedback to ensure consistency and low rejection rates. This contributed reliable ground-truth data for ASR models, voice assistants, and multilingual LLMs. My attention to detail and experience with accented and multilingual audio enabled consistent delivery.
