Next.js development
Customer portals, internal dashboards and product sites — from architecture to production and support.
We design and build portals, dashboards and product sites on Next.js. Full cycle: architecture, interface, backend, deployment, support. We took our own products — Lumi.CRM and ContractKit — to real users on the same stack.
What we build
- 01Interface — Next.js
- 02Data and access rights
- 03Integrations with your systems
We build all three layers, not just the front. That is why the product reaches production instead of staying a mockup.

Why Next.js?
All our own products run on it, so we know its sharp edges, not just the docs. It gives fast page delivery, decent indexing and one language on the front and the server.
How long does development take?
A site — from a couple of weeks; a portal or dashboard — from a month. The exact timeline comes after the brief, once the scope is clear. Before the brief we do not quote timelines — they would not be true.
What happens after launch?
We connect analytics and stay on support: fixes, improvements, incident duty. If you decide to run the project yourself, we hand over the code and documentation.
