How long does a project take?
It depends on the type of work. A website can be ready in 10 to 15 days, a custom plugin in 2 to 3 weeks and an app in 20 to 40 days. We give you an exact estimate once we know the project requirements.
What technologies do you use?
We work with modern technologies such as WordPress, WooCommerce, React, Flutter, Node.js, PHP, Tailwind, HTML/CSS and REST APIs, and platforms like Make, Zapier or Copilot Studio, depending on what fits the project best.
Can you connect my website to a CRM, payment gateway or other tool?
Yes. We integrate CRMs (HubSpot, Salesforce, Zoho, etc.), payment gateways (Stripe, PayPal, Redsys), booking systems, email marketing and any other tools you already use.
Do you offer maintenance after delivery?
Yes. We offer technical maintenance and update plans so your project stays secure, up to date and optimised. We can also take care of hosting and monitoring if you wish.
