AI / NLP & LLM Evaluation Alongside my language expertise, I work on AI/NLP projects involving Hindi and Marathi language data and AI-generated content. My AI/NLP expertise includes: • LLM response evaluation, ranking, and quality assessment • Instruction-following and prompt-response evaluation • Linguistic error categorization and hallucination detection • NLP data annotation and validation • AI training data creation for Hindi and Marathi • Human-in-the-loop (HITL) workflows • Machine Translation Post-Editing (MTPE) • Contextual rewriting and AI output refinement • Semantic accuracy, tone, register, and cultural evaluation • Search relevance, intent matching, and contextual correctness • Speech, text, conversational, and UI data annotation I have worked with Centific Technologies, TELUS International/TELUS Global, and Outlier AI on multilingual AI training, LLM evaluation, linguistic QA, data annotation, contextual rewriting, and MTPE projects.

I have more than 20 years of professional experience in electrical and instrumentation engineering, industrial automation, control systems, Industry 4.0, IIoT, power generation, and safety-critical environments. This allows me to understand technical content at the domain level rather than treating it as language alone. It is particularly valuable for tech
