Summary
👤
Senior🎓
Top SchoolBalázs Tarján is a Senior NLP Engineer with nine years of deep expertise in speech and language technologies, currently building NLP solutions at Constructor Tech from Budapest. He combines academic rigor—a PhD summa cum laude in machine learning for ASR—with hands-on product experience developing generative AI features, fine-tuning LLMs, and deploying monitoring pipelines on Azure at ELSA. His work spans end-to-end ASR systems, from data collection and annotation for accented, low-proficiency speakers to transitioning models to state-of-the-art end-to-end architectures and self-hosted vLLM deployments. He has led national-scale projects (media surveillance, municipal transcription) and adapted language models for enterprise clients, demonstrating both research depth and production-grade engineering. Pragmatic and detail-oriented, Balázs often bridges the gap between advanced model customization and robust operationalization in multilingual, morphologically rich settings.
