Blueprint: Software Engineering Handbook and Study Planner

A free, open source handbook that teaches software engineering in the order you should learn it, with the planning, practice and interview tools built around it. The content is 162 topics across 8 stages, from Java and SQL basics through SOLID, design patterns, object oriented design, LLD and HLD, to Forward Deployed Engineering (building production systems around an LLM: tool calling agents, streaming, embeddings and vector search). Every topic pairs a plain English note with Mermaid diagrams and code that compiles and runs, 604 source files and 113 diagrams in total, readable in an in-browser code workspace. The Markdown lives in the repo and a build step turns its front matter into a typed content manifest and a search index, so adding a note is a commit, not a CMS entry. On top of the handbook sits a Next.js 16 app with Better Auth accounts on Neon Postgres through Drizzle, and progress syncs across devices field by field, so two devices never lose each other's edits. A study planner splits the chosen stages into sprints and daily topics that fit the time you have, tracks time spent and a streak, and projects a finish date; a daily planner holds everything else, with list and board views. Finished topics come back on a widening spaced repetition schedule, practice drills make you type an answer before you reveal it, and 54 timed mock interviews run on a whiteboard with architecture stencils and a scoring rubric. A dashboard leads with today, an activity heatmap and readiness per track. The app comes in 17 color themes, each in light and dark, with a choice of reading and code fonts, and the home page lets visitors try every theme live.
