# Learning Path > Personal, structured, spaced-repetition-friendly curriculum aimed at a Senior Blockchain + Full-Stack Node.js developer bar. Every topic follows the same shape so the muscle memory of "where do I find the interview questions for this?" is always the same answer. **Open [`index.html`](./index.html) in a browser for the full visual dashboard** — categories, progress tracking, roadmaps, and a link into every module. --- ## How this is organised ``` D:\Learning-Path\ ├── index.html ← Global dashboard (start here) ├── README.md ← This file ├── _assets/ ← Shared CSS/JS + templates + STANDARD.md │ ├── Blockchain/ ← (Phase 2/3 — Solidity, EVM, ERC standards, DeFi, RWA) ├── BE Frameworks/ ← Node.js, .NET, Spring Boot (well populated) ├── FE Frameworks/ ← React, Angular (Phase 4) ├── Databases and DB management/ ← SQL, NoSQL (well populated) ├── Devops/ ← Docker, K8s, CI/CD, cloud, IaC (well populated) ├── Languages/ ← TypeScript, JS, Java, C#, Rust (Phase 4) ├── Javascript Data Structures and Data Types/ ← 63 coding tasks (well populated) ├── Mobile Developments/ ← React Native (Phase 4) ├── Technologies and Best Practices Architectures/ ← Patterns, Microservices (Phase 4) ├── Interview Prep/ ← System design, behavioural │ └── TEMPLATE-topic/ ← Reference implementation of the standard ``` Every topic (`//`) follows this shape: ``` / ├── README.md ← Topic overview ├── index.html ← Topic dashboard (progress + tabs + roadmap) ├── 01-Basics/ │ ├── README.md ← Level intro │ ├── 01-/ │ │ ├── README.md ← The lesson │ │ ├── lesson.html ← Beautiful renderer + syntax highlighting + diagrams │ │ ├── cheatsheet.md ← 1-screen rapid recall │ │ ├── interview.md ← Q/A tagged easy/mid/hard │ │ └── Tasks/ ← Hands-on practice │ └── 02-/… ├── 02-Intermediate/… └── 03-Advanced/… ``` The full contract is in [`_assets/STANDARD.md`](./_assets/STANDARD.md). A working example lives in [`TEMPLATE-topic/`](./TEMPLATE-topic/). --- ## Running the dashboard Every page works by double-clicking (`file://`) — no server needed. Each `lesson.html` carries an embedded copy of its Markdown, because browsers block `fetch()` of local files. **After editing any `.md` file, re-embed it** so the change shows when opening from disk: ```powershell # From D:\Learning-Path\ node _assets/generators/inline-md.mjs ``` If you'd rather not re-run it, serve the folder instead — over HTTP the pages fetch the live `.md` files, so edits show immediately: ```powershell python -m http.server 8000 # then visit http://localhost:8000/ ``` Progress is stored in your browser's localStorage keyed by `module:::` — clearing site data resets it. Note that `file://` and `http://localhost` keep separate progress. **Rebuilding / adding content:** run `node _assets/generators/build.mjs`. To add a category or topic, write a manifest — see [`_assets/generators/README.md`](./_assets/generators/README.md) for the schema and the full pipeline. --- ## Content status | Category | Topics | Modules | HTML dashboards | Lesson content | | :---------------------- | :------------------------------------------- | ------: | :-------------: | :------------- | | **Blockchain** | 14 (Solidity, ERC-20/721/1155, EVM, Security, Hardhat, Foundry, ethers, L2, X-chain, DeFi, RWA, Crypto) | 96 | ✅ full | ✅ written + study guides | | **BE Frameworks** | Node.js, .NET, Spring Boot | 41 | ✅ full | ✅ pre-existing | | **Databases** | SQL, NoSQL | 30 | ✅ full | ✅ pre-existing | | **DevOps** | Basics / Intermediate / Advanced | 15 | ✅ full | ✅ pre-existing | | **JS DSA** | 13 concept groups | 63 | ✅ full | ✅ pre-existing (`.js` files) | | **FE Frameworks** | React, Angular | 32 | ✅ full | ✅ pre-existing | | **Languages** | TypeScript, JS, C#, Java, Rust, Haskell | 131 | ✅ full | ✅ pre-existing | | **Mobile** | React Native | 23 | ✅ full | ✅ pre-existing | | **Architectures** | Algorithms, Design Patterns, Microservices | 44 | ✅ full | ✅ pre-existing | | **Interview Prep** | Jeneva Job (10 topic briefings + Project) | 14 | ✅ full | ✅ pre-existing (`.md` briefings) | | **Concurrency & Parallelism** *(new)* | Fundamentals, JS/Node, Go, Java/JVM, Rust, Distributed | 41 | ✅ full | ✅ written + study guides | | **Cybersecurity** *(new)* | OWASP Top 10, Web App Sec, Auth, Authz, Crypto, Threat Modeling, Secure Coding, API Sec, DevSecOps, Network Sec | 61 | ✅ full | ✅ written + study guides | | **System Design** *(new)* | Fundamentals, Data at Scale, Caching, Queues/Streaming, API Design, Load Balancing, Consensus, Case Studies | 45 | ✅ full | ✅ written + study guides | | **Observability & Reliability** *(new)* | Metrics, Logging, Tracing, SLOs, Chaos Engineering, On-Call | 28 | ✅ full | ✅ written + study guides | | **AI Engineering** *(new)* | LLM Patterns, RAG, Vector DBs, Agents, Fine-tuning, MLOps, Multimodal, AI Safety | 39 | ✅ full | ✅ written + study guides | | **Testing** *(new)* | Fundamentals, TDD/BDD, Mocking, Property-based, Mutation, Load/Perf, E2E, Contract | 34 | ✅ full | ✅ written + study guides | | **Requirements & Product** *(new)* | Requirements, User Stories, Discovery, Estimation, Prioritization, Metrics | 30 | ✅ full | ✅ written + study guides | | **Software Architecture** *(new)* | Fundamentals, DDD, Clean/Hexagonal, Styles, Documenting (C4/ADR), Evolutionary | 32 | ✅ full | ✅ written + study guides | | **CS Fundamentals** *(new)* | Operating Systems, Networking, Browsers, Database Internals, Compilers, Computer Architecture | 31 | ✅ full | ✅ written + study guides | | **Release Engineering** *(new)* | Version Control, CI/CD, Versioning & Releases, Kubernetes, Cloud Architecture, Platform Engineering | 31 | ✅ full | ✅ written + study guides | | **Maintenance & Evolution** *(new)* | Code Review, Refactoring, Legacy, Tech Debt, Zero-Downtime Changes, Dependencies | 30 | ✅ full | ✅ written + study guides | | **Data Engineering** *(new)* | Fundamentals, Modeling, Warehouses/Lakehouses, Orchestration, Streaming & CDC, Quality | 30 | ✅ full | ✅ written + study guides | | **Performance Engineering** *(new)* | Fundamentals, Profiling, Benchmarking, Frontend, Backend & DB, Capacity Planning | 30 | ✅ full | ✅ written + study guides | | **Web Platform & UX** *(new)* | Accessibility, i18n, Rendering Strategies, Web Standards, Design Systems, CSS Architecture | 30 | ✅ full | ✅ written + study guides | | **Engineering Leadership** *(new)* | Agile, Metrics, Tech Leadership, Writing, Mentoring, Staff Path, Team Design | 35 | ✅ full | ✅ written + study guides | | **Compliance, Privacy & Cost** *(new)* | Data Privacy, SOC 2/ISO 27001/PCI, Licensing, FinOps, AI Governance | 25 | ✅ full | ✅ written + study guides | | *New tracks in existing categories* | Go, Python (Languages) · NestJS (BE) · Next.js (FE) · PostgreSQL, Redis, Elasticsearch (Databases) | 45 | ✅ full | ✅ written + study guides | | **Total** | 26 categories | **1,025 lessons** | | | Every category has a **category-level `index.html`**, every topic has a **topic dashboard** with tabbed levels, and every module has a **`lesson.html`** that renders the Lesson / Cheatsheet / Interview Qs / Tasks tabs from its `.md` files. No page returns 404 or a raw directory listing. **Authoring status:** every lesson is written — a 1,000–1,600-word lesson, a one-screen cheatsheet, and 6–8 interview questions per module — and every new topic has a study guide with curated canonical resources. Shared authoring rules live in `_assets/generators/AUTHORING-BRIEF.md`. Code examples were reviewed but mostly not compiled or executed (some Node.js and Python examples were run); invented numbers, names and sample output are labelled illustrative. The pre-existing categories (BE Frameworks, Databases, DevOps, Languages, FE Frameworks, Mobile, Architectures, JS DSA, Interview Prep) keep their original content; their original topics do not yet have study-guide pages. --- ## Recommended sequence (Senior Blockchain + Node.js) ``` Foundation: JS Deep Dives → TypeScript → Node.js Backends → SQL + NoSQL → Docker / K8s Blockchain: Solidity → ERC-20 / 721 / 1155 → Security → Hardhat + Foundry → L2 + Cross-chain → RWA / DeFi ``` Or: **Path 1 — Full-Stack Node.js first (5–6 months)** 1. TypeScript refresh (2 wk) 2. Node.js backends deep-dive (6 wk) 3. Databases: SQL + NoSQL (4 wk) 4. React + system design (6 wk) 5. DevOps: Docker → K8s (4 wk) **Path 2 — Blockchain-specialist track (4–6 months)** 1. Solidity fundamentals (3 wk) 2. ERC-20 → 721 → 1155 (3 wk) 3. Smart Contract Security (4 wk) 4. Hardhat / Foundry / Ethers (3 wk) 5. Layer 2, Cross-chain, RWA (4 wk) 6. Interview / capstone project (2 wk) **Path 3 — Combined senior bar (7–9 months)** Path 1 in parallel with Path 2 modules 1–3, finishing with a capstone that integrates a React frontend + Node.js backend + Solidity smart contracts. --- ## Adding new content To add a topic: 1. Copy `TEMPLATE-topic/` into the target category folder, rename it. 2. Update `/index.html` — the `TOPIC_SLUG` and `TOPIC_DATA.levels` block. 3. For each module, copy `_assets/lesson.html.template` into the module folder as `lesson.html` and fill the four `{{...}}` placeholders. 4. Write the module's `README.md`, `cheatsheet.md`, `interview.md`, and `Tasks/*.md`. 5. Update the root `index.html` `CATEGORIES` array so the new topic's count is reflected in the global dashboard. Full recipe: [`_assets/STANDARD.md`](./_assets/STANDARD.md). --- ## Tips for using the material 1. **Consistency > intensity** — one hour daily beats seven hours on Sunday. 2. **Type every snippet** — no paste. If it hurts, that's the muscle building. 3. **Debug actively** — understand each error before Googling it away. 4. **Finish before switching** — complete every module in a topic before starting the next. 5. **Interview questions ARE the review** — re-reading `interview.md` files is your spaced repetition. 6. **Build one integrative project per tier** — a small deliverable per level pins the concepts.
