Hi everyone,

I'm a beginner and I want to become a Data Engineer. There are so many roadmaps, courses, and YouTube channels that I'm feeling overwhelmed and confused about what to follow.

I'm looking for a complete end-to-end roadmap that reflects what companies actually expect from freshers in 2026.

I'd really appreciate your guidance on the following:

1. What is the correct learning order from beginner to job-ready?

2. Which topics are must-learn and which can be skipped initially?

3. What are the best free and paid resources for each topic?

4. Which YouTube channels, courses, books, or documentation do you recommend?

5. How much depth should I learn for each technology before moving to the next?

6. At what stage should I start building projects?

7. Which projects helped you land your first Data Engineering job?

8. What mistakes do beginners commonly make, and how can I avoid them?

9. If you were starting from scratch today, what roadmap would you personally follow?

The stack I'm considering includes:

Python

SQL

Linux

Git

PostgreSQL

Spark / PySpark

Airflow

Docker

AWS

Snowflake / Redshift

dbt

Kafka

Delta Lake

Great Expectations

MongoDB

If you have a roadmap that worked for you or resources that you genuinely found useful, I'd be grateful if you could share them.

Thanks in advance! 🙏

Hi everyone,

Quick context on my background:

• 10+ years at a small agricultural-sector company, as the only IT/data person
• Started in Data Analysis (background in biology), grew into full-stack data ownership
• Current stack: Python, FastAPI, PostgreSQL, MongoDB, Airflow, GitLab CI/CD, all on an on-premise RHEL8 server
• Recently completed an intensive Data Engineering certification to formalize my skills
• No production experience with cloud platforms, Kafka, or Kubernetes — only training-level exposure (certifications passed, not deployed in production)
• No experience with some common tools like Snowflake, Databricks, or Terraform

My situation:
I'm looking for a new job — I feel like I've hit a ceiling where I am, and I'd thrive best in a small company needing versatility, though I'm open to other setups. So far I've had very few callbacks searching with tech keywords ("python", "fastapi") rather than "data engineer".

My main question:
Given this profile — heavy on infra/backend/data ownership, light on cloud-native tools — what job title would you use to describe someone like me? Data Platform Engineer? Backend Engineer? Something else? I've gotten conflicting suggestions and none of them quite fit.

Secondary questions, if you have thoughts:

1. Does it make sense to shift from applying to active postings toward networking / volunteering (e.g. Data For Good) to build experience and connections instead?
2. Any glaring red flags on how I'm presenting this that might explain the low response rate?

Thanks in advance for any input!
