About
Built by a developer, for developers in transition

AiNotes exists because the hardest part of moving from software development into AI engineering isn't finding information — it's finding explanations that actually fit a developer's mental model.
Every note in this library is handwritten and drawn: transformer blocks sketched step by step, RAG pipelines diagrammed end to end, agent loops annotated with the failure modes you'll meet in production and in interviews. The goal is simple — take you from developer to AI engineer with notes you can actually learn from.
The audience is specific: Java, Python and JavaScript developers moving into GenAI; Appium, Salesforce and low-code professionals switching domains; backend engineers preparing for AI Engineer and GenAI Engineer roles; and anyone learning LLMs, RAG, AI Agents and AI system design with interviews on the horizon.
