# Sanjay Ram A — AI Engineer Portfolio > Portfolio of Sanjay Ram A, an AI engineering student from Tamil Nadu building machine learning systems, fine-tuning LLMs, training models, and shipping applied AI products. Founder of [Dotwellabs](dotwellabs.web.app). Sanjay Ram A designs and builds practical AI systems — from machine learning experiments, RAG pipelines, and on-device LLM inference to data-driven products that turn messy information into usable decisions. Open to AI engineering roles, research collaborations, and ML projects. - Site: https://sanjayrama.vercel.app/ - Email: sanjayram26102005@gmail.com - Location: Tamil Nadu, India - Status: Available for AI engineering roles, research collabs, and ML projects ## About - Who I am: AI engineering student from Tamil Nadu building real products on the side. Started with curiosity about how models actually work and ended up shipping apps, fine-tuning LLMs, and founding Dotwellabs. - Focus: applied machine learning, mobile AI, and product thinking. Cares about systems that are measurable, reproducible, and useful outside a notebook. - Experience: 4+ projects shipped (from Play Store apps to hackathon winners); 2+ years building AI systems, models, and data products; models and datasets published on Hugging Face. - Interests: Applied LLM systems (finetuning, RAG, agents, evaluation, prompt design), LLM training (dataset curation, SFT, parameter-efficient tuning, evaluation), data products (dashboards, APIs, interfaces for model outputs), and model evaluation (metrics, error analysis, reproducibility). ## Home - [Portfolio Home](https://sanjayrama.vercel.app/): AI Engineer Portfolio — building machine intelligence with a clear signal.
