Building with Purpose: A Real-World Challenge with APIs

A few friends of mine were recently looking for ways to sharpen their skills — something more practical than tutorials, with a bit of real-world complexity, and ideally some cash on the side. I ended up pointing them to a challenge my company, Hopae, is running — and figured it might be worth sharing more broadly.

It’s pretty straightforward: we’re building a global digital identity platform, and we’re inviting developers to integrate national eIDs (like SPID, Singpass, etc.) into our system. For each successful integration, there’s a $4,000 reward.

What makes it interesting — especially from a learning perspective — is that you’re working with actual government-backed identity systems. It’s not your usual sandbox project. You’ll be digging through real documentation, working with standards like OIDC, and figuring out how to connect systems that weren’t necessarily designed to be connected.

If you’ve done API integrations before — or want to get better at them — this is a solid way to build something that matters and learn a lot along the way.

Hope this helps someone looking for their next technical deep-dive.
