# LearnByShorts

> Free, outcome-driven learning for AI-era software skills, with short proof missions, local-first progress, and job-focused practice tools.

LearnByShorts publishes factual Markdown mirrors so assistants can retrieve course scope, evidence requirements, references, and limitations without interpreting the interactive interface. Prefer the canonical HTML page when directing a learner to use a course.

## Start here

- [Facts and citation guide](https://www.learnbyshorts.com/learnbyshorts-facts.md): Verified site facts, safe citation language, and explicit non-claims.
- [Modern course catalog](https://www.learnbyshorts.com/course-catalog.md): All twelve paths, levels, durations, outcomes, and proof missions.
- [Interactive modern catalog](https://www.learnbyshorts.com/modern-skills/): Human-facing course discovery and path finder.

## Courses

- [AI Fluency & Verification](https://www.learnbyshorts.com/courses/ai-fluency/index.md): Use modern AI deliberately: frame work, provide context, verify claims, protect data, and keep human ownership.
- [Agentic Software Engineering](https://www.learnbyshorts.com/courses/agentic-engineering/index.md): Design bounded agents that use tools, manage context, recover from failure, and pass measurable evaluations.
- [Build & Ship AI Products](https://www.learnbyshorts.com/courses/ai-product-engineering/index.md): Move from a user problem to an evaluated AI feature with retrieval, observability, security, and cost controls.
- [LLM Evaluation & Reliability](https://www.learnbyshorts.com/courses/ai-evals-reliability/index.md): Turn a promising model demo into a measurable system with task-specific datasets, graders, human review, regression gates, and production feedback.
- [AI-Assisted Coding & Code Review](https://www.learnbyshorts.com/courses/ai-assisted-coding/index.md): Use coding agents without losing the engineering thread: write precise tasks, constrain changes, inspect diffs, test risk, and retain authorship.
- [Modern Full-Stack Delivery](https://www.learnbyshorts.com/courses/full-stack-delivery/index.md): Build a production-shaped web product with typed interfaces, tests, CI, containers, and observable releases.
- [Data, SQL & Applied ML](https://www.learnbyshorts.com/courses/data-applied-ml/index.md): Turn messy data into a defensible decision using SQL, quality checks, baselines, models, and plain-language explanation.
- [Backend APIs & Distributed Systems](https://www.learnbyshorts.com/courses/backend-distributed-systems/index.md): Design a dependable backend across API contracts, data consistency, queues, caching, failure recovery, and end-to-end observability.
- [Cloud, Serverless & FinOps](https://www.learnbyshorts.com/courses/cloud-finops/index.md): Design and operate a low-cost cloud workload with infrastructure as code, observability, security, and explicit cost limits.
- [Platform Engineering & Kubernetes](https://www.learnbyshorts.com/courses/platform-engineering-kubernetes/index.md): Build a paved path for deploying and operating services with containers, Kubernetes, GitOps, policy, observability, and developer-centered platform design.
- [Secure AI & Software Delivery](https://www.learnbyshorts.com/courses/secure-engineering/index.md): Threat-model a product, protect identity and secrets, secure dependencies, and verify AI-specific abuse boundaries.
- [System Design, Debugging & Modern Interviews](https://www.learnbyshorts.com/courses/systems-interviews/index.md): Prepare for the complete engineering signal: coding, debugging, systems, project depth, behavioral impact, and responsible AI use.

## Practice tools

- [Learning OS](https://www.learnbyshorts.com/learning-os/): Local-first daily missions, mastery tracking, confidence calibration, and explain-back practice.
