2 years ago, we launched @master_backend.

It has become a global community for backend engineers.

We are excited to launch the Mastering Backend Academy.

We aim to raise 500 solid backend engineers in the next 24 months.

Commit or do not, but decide it today rather than on Wednesday at nine.

Open one terminal project. Choose an input yourself — an awkward one. Run your program. Read what it prints.

One project. Your input. Your program's real output. Today.

If you are not going to do that, be honest that you are collecting courses, and stop calling it preparing. That is a legitimate choice. It is just not the same choice.

One question this weekend, and answer it honestly rather than quickly.

When did a machine last tell you your work was wrong — and you could not argue with it?

[Mastering Backend @master_backend]

Developers, let's talk. What's the hardest part of learning AI engineering?

Reply with your answer.

We're preparing a live technical masterclass @master_backend to explore how backend engineering and AI come together.

If you have to go back more than a month, that is the finding. Not a reason to feel bad; a reason to change what you do on Monday.

The most common way to fail a task you actually understood:

you compute the right answer, and then you decorate it.

A friendly label. A prompt. A blank line you never thought about.

Techrity joins the partners backing 200 AI engineering scholarships for Africans, alongside Starnet Tech, Labspace Nigeria, Droom Work, Learn2Earn NG, AltSchool Africa and Data Science Nigeria.

Learn what a context window really costs your backend.

The model remembers nothing between requests. Your code resends the history every time, so every turn pays for the whole conversation again.

[Mastering Backend @master_backend]

This is the whole loop, and it takes about a minute.

Open a project. Real terminal in the browser. Run your program. Give it the input you chose. Read what it prints.

That last step is the grade.

Fail one task properly this week. Read what your program printed, not what you meant it to print.

The second most common way: reading a crash as a wrong answer.

A program that exits with an error has not answered incorrectly. It has not answered. Those are different bugs and they live in different places.
