MyLearnStack

Learn any stack, one module at a time. Every tool here sits in a cluster of rivals, and what carries between them is the durable part — the rest is rewritten on migration. 18 domains, 141 clusters. An entity appears only once it is actually being learned.

Domains

• Universal Foundations

  Needed regardless of specialisation. The highest density of Layer 0–1 on the map, and therefore the best return per hour spent…

  10 clustersLayers 0–2

• Programming Languages

  Layer 2 across the board: individual languages hold their shape for 5–10 years, and the concepts under them do not decay at all.

  9 clustersLayers 0–21 started

• Frontend Development

  The highest Layer-3 density on the map. Most of what looks foundational here churns on a 2–5 year cycle, and the durable part is…

  11 clustersLayers 1–3

• Backend Development

  Python frameworks, JS/TS backend, JVM backend, and more.

  8 clustersLayers 1–3

• APIs & Integration

  API styles, REST API design, Specification & tooling, and more.

  7 clustersLayers 0–3

• Databases & Storage

  Relational, Managed & serverless SQL, Document stores, and more.

  12 clustersLayers 0–3

• Data Engineering & Big Data

  Distributed processing, Spark job interfaces, Single-node analytics, and more.

  11 clustersLayers 0–3

• AI & Machine Learning

  Math foundations, Core Python data stack, Classical ML, and more.

  9 clustersLayers 0–3

• LLMs & Generative AI

  The fastest-moving domain on the map. Almost everything here is Layer 3 or worse, so consume it, do not study it — with the…

  8 clustersLayers 2–3

• Cloud Computing

  Major providers, Developer clouds & PaaS, AWS essentials, and more.

  7 clustersLayers 1–3

• Security

  Application security, Identity & access, Cryptography basics, and more.

  7 clustersLayers 0–3

• CS Fundamentals & DSA
