Language & Data Ops | EN-BG

With over 12 years and 15,000 hours of freelancing experience, I specialize in localization, linguistic QA, and multilingual language data workflows, with a particular focus on Bulgarian-English projects. Over the past decade, I’ve worked across software localization, technical and legal translation, structured content environments, and long-term operational support for international clients. My work combines linguistic precision with an understanding of how language functions inside real systems, platforms, and workflows. Alongside my freelance work, I am currently completing an MA in Language and Mind: Linguistics and Cognitive Science, with a research focus on computational linguistics, language modeling, and rule generalisation in LLMs. My areas of work include: • Software and website localization • Linguistic QA and validation • Bulgarian-English language data annotation • AI output evaluation and RLHF-related workflows • Terminology and consistency management • Structured multilingual content operations • Annotation guidelines and quality review I am particularly interested in high-context linguistic tasks that require ambiguity reduction, consistency, and careful handling of morphological and syntactic nuance. Clients value my work for its reliability, precision, and long-term maintainability, not just speed or volume.
