The Analytics Engineer roadmap

Each topic below carries a study note, real reading, and practice questions in the app. A topic unlocks when you pass the one before it, so the order is the path, so you are never guessing what to learn next.

Phase 1Analytics engineering foundations

SQL mastery

SQL is the analytics engineer's primary instrument.

Data modeling basics

Modeling starts with grain: the precise thing one row represents.

The modern analytics stack

The modern stack is ELT: extract and load raw data into a cloud warehouse, then transform it there as version-controlled SQL.

Phase 2Analytics engineering transformation

dbt and transformations

dbt turns SQL SELECTs into a managed pipeline.

Incremental models

Incremental models process only new or changed rows to save time and cost.

Testing data

Tests encode your assumptions about data so violations fail loudly.

Phase 3Analytics engineering modeling

Dimensional modeling

Dimensional modeling arranges data as a star: a central fact table at one grain surrounded by denormalized dimensions.

Metrics and semantic layers

A semantic layer defines each metric once as governed logic so every dashboard and tool resolves the same number.

Slowly changing dimensions

When dimension attributes change over time, how you handle history matters.

Phase 4Analytics engineering quality

Data quality tests

Beyond schema tests, quality means detecting when data stops behaving: staleness, volume drops, and range anomalies.

Documentation

Documentation that lives with the code stays true.

Data lineage

Lineage is the dependency graph of your data: which models, columns, and dashboards depend on what.

Phase 5Analytics engineering in production

Orchestration

Orchestration decides when and in what order jobs run.

Cost and performance

Warehouse bills scale with bytes scanned and compute time.

Serving to BI tools

The last mile is the serving layer.

Reading for this path

The primary sources behind the topics above, all free to read.

Coming from another job?

Most people on this path arrived from somewhere else: engineering, analysis, testing, product, support, compliance, design. Onboarding asks what you do today and builds a short starter run out of the gaps, so you begin from what you already know rather than from chapter one. See how it works.

Applied Scientist

Model adaptation, evaluation, and prototyping against real product problems. Take research from paper to production.

Computer Vision Engineer

Image and video models, VLMs, detection, and visual inspection. Ship systems that see and understand the world.

Context Engineer

Context windows, memory systems, retrieval strategy, and token budgeting. Get the right information in front of the model every time.

Conversational AI Designer

Dialog flows, persona design, voice and chat UX, and escalation paths. Craft conversations people actually want to have.

Data Scientist

Experiment design, statistics, causal inference, and modeling. Turn data into decisions and explain why.

Edge AI Engineer

On-device models, quantization for mobile and embedded, and offline inference. Run AI where the cloud can't reach.
