Engineers

Ship code that is clearly yours.

Problem: Anyone can copy a polished repo.

Fix: We check your commit history, then a person confirms the work.

What you'll prove

Who is it for?

Students and developers who want to show code they really wrote.

What does it cost?

Paths, proofs and checks are free. The Arena adds a team and weekly challenges for $12 a month. Join the Arena

Who confirms my work?

First we check the repo is yours, with commits on 5 or more days. Then a person who knows the field reads it.

Who sees it?

You choose. Adults can share a public link. Work by anyone under 18 is always private.

Software Engineering Foundations

Software engineering is not coding — it's the discipline of building systems that work under real constraints. Every proof here is a real engineering artifact.

Skills

AdvancedUndergraduate

Mechanical Engineering

Mechanical engineering starts with a drawing. FreeCAD is free and open-source. SimScale has a free FEA tier. You don't need a machine shop to prove you can engineer.

Skills
1 required + 4 opt44w
AdvancedUndergraduate

Electrical & Electronics Engineering

From circuit analysis to embedded firmware. LTspice and Falstad run in your browser. Wokwi simulates Arduino without hardware. Every proof is a schematic, simulation result, or documented test.

Skills
1 required + 6 opt52w
AdvancedUndergraduate

Civil & Structural Engineering

Civil engineering proofs are calculations that keep things standing. SkyCiv has a free tier. BGS and USGS geological data are publicly available. The proof is the calculation, not the construction.

AdvancedUndergraduate

Chemical & Process Engineering

Chemical engineering is mass balances, energy balances, and not blowing things up. DWSIM is free and open-source. Every proof is a calculation, diagram, or safety analysis reviewed by a process engineer.

Outcomes

Milestone map

Ship AI Products in Production

4 milestones · 12 weeks

Ship a real AI-powered product to production and keep it live with real users — proof is usage data and a technical post-mortem, not a tutorial.

Milestone map

First App Shipped (Curriculum Complete + Public Repo)

4 milestones · 12 weeks

Complete a free coding curriculum and ship one self-contained program that solves a real problem and runs on someone else's machine — not a certificate.

Milestone map

Become Data Analyst

4 milestones · 12 weeks

Take a real 10,000+ row dataset from raw to a documented, visualised answer — proof is the analysis and what it honestly cannot conclude.

Milestone map

Ship a Full Stack App From Scratch

4 milestones · 12 weeks

Build and deploy a working full-stack app — real auth, real database, a public URL — that solves an actual problem, not a tutorial clone.

Milestone map

Ship a Mobile App to a Real App Store

4 milestones · 12 weeks

Ship a working mobile app to a real app store listing, built to use at least one real device capability beyond the screen.

Milestone map

Run Production Infrastructure Reliably

4 milestones · 12 weeks

Automate a real, currently-manual deployment or infrastructure task into a CI/CD pipeline or infrastructure-as-code that runs without human intervention.

Milestone map

Ship and Sustain a Reliable Service

4 milestones · 12 weeks

Set real SLOs for critical services, measure the actual reliability gap against them, then close it and defend the change to a panel of practitioners.

Milestone map

Lead Incidents From Alert to Resolution

4 milestones · 12 weeks

Audit a real incident response process against MTTD/MTTR and post-mortem completion, fix the specific failure modes, then show the improved metrics.

Milestone map

Coding Bootcamp Graduate (Portfolio Project Deployed)

3 milestones · 16 weeks

Go from zero to job-ready developer through an intensive program.

Milestone map

Data Analysis Project (Peer-Reviewed, Dataset + Findings)

3 milestones · 10 weeks

Go from spreadsheets to Python pandas and produce real insights.

Milestone map

Software Tool Power-User Review (Verified)

3 milestones · 8 weeks

Go from beginner to power user in a tool essential to your work.

Milestone map

First Three Projects Shipped (Beginner to Public App)

5 milestones · 16 weeks

Write, run, and ship your first Python programs — from a terminal hello-world to a deployed web app that real strangers can use.

People and recorded checks confirm the work here. Powstik does not give degrees or licences.
