With over 11 years of hands-on experience in AI, I specialize in building scalable, production-grade ML systems that drive tangible business outcomes across domains like Recruitment, Insurance, FinTech, AdTech, Legal, and News. I lead with a product mindset, combining deep technical know-how with a strong sense of execution. *My Expertise:* LLMs & GenAI: Built and fine-tuned proprietary domain-specific embedding models using HuggingFace Transformers, MiniLM, and LLaMA 2 with QLoRA and LangChain-based RAG pipelines. Search & Ranking Engines: Architected scalable retrieval systems including AI-enhanced resume-job matching, semantic search, and ranking models using OpenSearch and Sentence Transformers. AI Agents & Interview Automation: Developed dynamic, sentiment-aware AI interviewers using OpenAI + LangGraph to reduce manual screening by 40%. Data Pipelines: Designed and deployed big data pipelines for job ingestion, skill enrichment, and real-time matching across 600M+ records. AI for Business: Delivered production-grade AI solutions (resume parsers, recommenders, interview bots) with 2× retrieval precision, 20% boost in profile accuracy, and 87% rec precision in insurance plans. *Tech Stack & Tools* Languages & Frameworks: Python, PyTorch, TensorFlow, Keras, PySpark, SQL, JavaScript, React AI & GenAI: HuggingFace, LLMs, GPT, BERT, LangChain, RAG, LoRA, QLoRA, OpenAI, Prompt Engineering CV & NLP: OpenCV, Tesseract OCR, NLTK, SpaCy, Transformers Big Data & Infra: Hive, Spark, Docker, AWS, REST APIs, MongoDB, OpenSearch, Jenkins *Philosophy & Approach* Understand First: I believe the best solutions start with asking the right questions, not rushing to the code. Innovate Iteratively: I iterate fast, test boldly, and always aim for practical outcomes over theoretical perfection. Build with Impact: My AI solutions are deeply rooted in solving real-world pain points — whether it’s improving recruiter efficiency or delivering precise recommendations. *Let’s Connect* I'm always open to new ideas, challenging conversations, and collaborative problem-solving. Whether you're exploring AI transformation or looking to brainstorm over the future of work and hiring — I’d love to chat. "Generative AI isn’t the future — it’s the now. Let’s build it, together."
