Engineers

Prove the code is yours.

Anyone can push a polished repo. Link your GitHub, and we check the history before a person confirms the work.

Sample: what a finished Trophy Case looks like

The cost of doing nothing

A reviewer can't tell in five minutes who wrote the code.

Repos can be copied, forked or generated.

Stars and green squares say little about skill.

Real builders compete with work they didn't do.

Show the history, then get it confirmed.

What you get

What changes

History, checked
Once your GitHub is linked, we check the repo is yours and has real commit history.
A person confirms the rest
Someone who knows the field reads the work and confirms it.
Free curricula
Computer Science, Data Science, AI Engineering, AI Research and Robotics, all free.

The plan

How it works

Pick a pathChoose a path or a single outcome below. Every resource is free.
Do the work and post your proofBuild it in a public repo and link it, with a README that says how to run it.
It gets confirmedYour repo is checked automatically, then one person who knows the work confirms it. It goes on your Trophy Case with a seal anyone can check.

Honest proof

Proof you can check, not a claim you have to trust.

Every check records what it saw, and every confirmation is signed. Anyone can verify the seal.

Confirmed by people who saw the work
Proof Seals anyone can check
Under-18 Trophy Cases private by default

Pricing

Free, always

Every path and outcome, posting proofs, verification, your Trophy Case and Powstik Varsity.

The Arena: $12 a month

Do this Portfolio with a group, with weekly challenges. Cancel anytime.

Group challenges, every week. Team up, do real work, climb the league.

What you get

1. Team up and climb — Your team ranks in a weekly league.
2. Get checked sooner — Your proof moves up the line.
3. A Trophy Case to show — One link with all your checked work.

How it works

1. Pick a challenge. Team up with 2 friends.
2. Do the work. Upload your proof.
3. Three real people check it. Your team climbs.

Questions

Is it free?

Yes. Paths, outcomes, proofs, verification and your Trophy Case are free. The paid Arena, doing this Portfolio with a group and weekly challenges, costs $5 or $12 a month depending on your country. Cancel anytime.

What exactly is checked automatically?

That the repository belongs to you, is not an unmodified fork, and has commits on at least 5 different days. Live sites must answer over a valid certificate. A person still confirms the work is good.

Does an AI decide whether my work is verified?

No. People and machine checks decide. For an adult's public code, an AI gives feedback and must quote the code it judges. Work by anyone under 18 is never sent to an AI.

Who can see my work?

You choose. Adults can make their Trophy Case public. Trophy Cases of anyone under 18 are private by default and never get a public link. Clinical health proofs are always private.

Do I keep my proofs?

Yes. They belong to you and stay on your Trophy Case, with a seal anyone can check.

Free curricula, and code that's checked, not just claimed.

More detail

Engineers gathers the technical paths: the free CS, Data Science, AI Engineering, AI Research and Robotics curricula and the engineering degrees' worth of practice paths. Code is checked against GitHub once you link it, live sites against the web, and a person who knows the field confirms the work.

What is the Engineers Portfolio?

The Engineers Portfolio gathers the Powstik paths and outcomes that fit that goal. You do real work, get it checked, and share one link.

Who is it for?

It is for people who want to build a Engineers record with real work. You pick the paths and outcomes that fit your goal.

What costs money?

Arena, the paid plan with teams and a league, has a monthly price shown on the Join button. Paths, proofs, checks and your Portfolio link have no charge.

How does verification work?

A real person who knows your work signs in and checks each proof. You can never check your own proof. Paying for Arena never skips this check.
