Notes from the Journey

My RAG service ranked its default search results worst-first, and nothing in the logs or the tests said so. How I found it and what I changed afterwards.

My RAG API was dead for weeks while every dashboard said it was fine. The cause was a dependency nothing in the request path needed.

How I put BullMQ, WebSockets and Playwright together in AutoFlow Pro, and what free-tier hosting forced me to decide.

What writing 62 Hardhat tests for an ERC-721 contract and a marketplace contract taught me about edge cases and access control.

What changed when I moved from ordinary web development to writing and testing Solidity contracts.

Leading a team of five on a thesis project that turns notes into flashcards and quizzes, and the context problem that came with the AI chat.
