Before you decide

Portfolio FAQ: references, timelines and ownership

  • Yes. We'll put you in touch with at least one of the clients on this page. They're happy to share their experience, scope and timeline.

  • Every project on this page came from a different vertical: retail security, distribution, events, nutrition, B2B tech. The patterns (fixed scope, milestone delivery, owned code) carry over. The exact numbers depend on your traffic and model.

  • Most projects on this page took 6–12 weeks end to end. The fastest was 2 weeks for a landing launch. You'll get a fixed timeline in the quote.

  • Always. You get the repo, domain, hosting credentials and design files on day one after launch. No lock-in.

  • Yes. Several cases here started as rebuilds of WordPress or no-code sites. We migrate content, preserve SEO and rewrite the stack so it stops breaking.

  • That's most of what we do. Landing pages and simple corporate sites don't always make it into the portfolio, but they share the same workflow. Ask for a quote, and we'll tell you honestly if a template shop is a better fit.
