Why us
Properly is a short word for a long list.
Properly means a site that loads fast on an old phone and a slow connection. Pages your team can edit without breaking the layout. Forms, checkout and search tested before anyone else sees them. Clean code without bloat, so the next feature — or the next developer — doesn't start with a rewrite.
YASS is a web development studio in Bucharest, Romania. We design and build websites, shops and apps for businesses — and white-label for agencies.

What we build
What we build, and how far it goes.

- Webflow and Framer sites, built to the design
- Migrations between platforms

For the sites we build: updates, backups, monitoring, and a person to email when something looks wrong — the same people who built it.
- Updates, backups, monitoring
- Performance and security checks
- A person to email when it looks wrong
- 06
White-label for agencies
Development for studios with more design than dev capacity. Your client, your brand, our code.

- Introduced by name, or not at all
Built to last. Launched on time.
Built properly, launched on time, and still around when you need us.

- Handover docs and full access
White-label development for studios with more design than dev capacity. Your client, your brand, our build.

Project if you know what you need. Agency if you run a studio and send work regularly. Care once we've launched it and it needs to keep running. Not sure? Write and we'll tell you — even if the answer is “not yet”.
