In this post, I dive into the development of English Coach Pro, an EdTech initiative focused on creating interactive, context-aware AI coaching. I explore the core architectural decisions and environment setups needed to transform general-purpose LLMs into structured, pedagogical assistants.</p> <p>From setting up conversational guardrails to managing state and integrating Cloud workflows, I share the practical lessons learned while building this stack. Whether you are curious about EdTech innovations, LLM orchestration, or scaling AI applications, this breakdown offers a hands-on look at how custom LM environments can reshape digital learning.<br> <a href="https://asacademic.com/english-coach/" rel="noopener noreferrer">https://asacademic.com/english-coach/</a></p> ai programming python machinelearning
