Custom software and SaaS
We design, build and run web applications, portals and multi-tenant SaaS platforms, with roles, billing and integrations. We built and run Keruja, our own SaaS, so we know what production really takes.

FAQ
Questions we get asked.
Short answers, in plain English.
What do you build?
Web applications, customer and staff portals, and multi-tenant SaaS platforms: systems where several organisations, roles and user types share one product safely.
Which technology do you use?
Mostly TypeScript with Next.js on the front end, NestJS for the API, PostgreSQL for data, Redis for background jobs and Stripe for billing. We choose what suits the job and what you can maintain.
Can you work on an existing system?
Yes. We start with an audit of the code, hosting and data, then propose a phased plan with a fixed price per phase.
Do you host and support it after launch?
Yes. We run our own SaaS in production and can host, monitor and maintain yours, or hand it over to your team.
How is a project priced?
In phases. Each phase has a written scope and a fixed price, agreed before work starts.
