Akshay Pachaar
Akshay Pachaar is an AI engineer, educator, and co-founder with over eight years of experience in machine learning, computer vision, and natural language processing[^c1]. He is the co-founder of Daily Dose of Data Science, a community of over 450,000 ML and AI practitioners, and his educational content has been read more than 200 million times across platforms[^c2][^c3]. He holds a dual degree in mathematics and electrical engineering from BITS Pilani[^c4] and has guest lectured on AI engineering at the Massachusetts Institute of Technology[^c5]. Pachaar is the inventor of four granted US patents in navigation and mapping technology[^c6].
Pachaar's career spans roles as a computer vision intern at HERE Technologies, lead data scientist at TomTom, senior research engineer at Lightning AI, and co-founder of Daily Dose of Data Science. He maintains an active presence on X (Twitter), GitHub, and through his newsletters ML Spring and Daily Dose of Data Science, where he publishes tutorials on large language models, retrieval-augmented generation, AI agents, and machine learning fundamentals. In 2026, he formulated the Agent Harness Engineering framework, which maps the LLM to a CPU and the agent harness to an operating system[^c7] and demonstrated that the same model can produce dramatically different results depending on the harness wrapping it[^c8].
