Ehsan L.

I am a PhD-level AI Research Scientist and Consultant with 5+ years of experience delivering advanced solutions in natural language processing (NLP), large language models (LLMs, e.g., GPT-4, ChatGPT, BERT), machine learning, and robotics. My expertise covers the full project lifecycle: from model selection and fine-tuning to deployment, evaluation, and integration into real-world applications. My background includes: Fine-tuning and deploying LLMs (GPT-3.5/4, ChatGPT, BERT, LLaMA) for automated assessment, chatbots, and education technology Developing robust NLP pipelines for text classification, summarization, and content generation Leading multi-agent reinforcement learning and robotics projects (ROS2, PyTorch, Python) Delivering solutions for EdTech, academic research, and commercial AI clients Published in top venues (IEEE RA-L, AAAI, NeurIPS, ACM SIGCOMM) and recipient of multiple international awards Services I offer: LLM/ChatGPT fine-tuning & integration for your platform NLP system design, evaluation, and bias mitigation Educational AI (automated grading, intelligent tutoring, content analysis) Robotics AI: multi-agent systems, RL, perception, path planning Research consulting, technical writing, and grant proposal support Let’s discuss how I can help you bring state-of-the-art AI into your project! I am open to both one-time consulting calls and long-term collaborations. Open to a 30-minute discovery call to discuss your project needs. Click “Invite” to start a conversation.
