The other side of us
The hands that code
also make jewelry.
At another workbench, we choose colors, bend wire and turn someone’s story into jewelry. Halo.Project is where our ideas of warmth, companionship and connection take shape.
Working with customers, orders and everyday operations keeps one thing clear: a good system has to take care of people. We bring that understanding to your software, too.
How we work
One conversation
We spend 30 minutes listening to the current situation, then clarify the problem, timing, and most useful next step together.
Scope and proposal
You get the scope, deliverables, schedule and price in writing, with no vague line items that leave room for later add-ons.
Development
Every week we share progress you can check, along with any risks, so you always know where the project stands.
Delivery and handover
The code, documentation, deployment access, and operating knowledge are yours, with clear conditions for taking over.
