 06.1 
## What platforms and portals do we build?

For companies where off-the-shelf tools no longer suffice - because the process is specific, the scale is large, or there are too many integrations to wire together manually. For startups building a SaaS product from scratch.

**SaaS platforms** - products with login, subscription and user dashboard, designed from MVP through scaling.

**B2B portals and extranets** - client zones, partner dashboards and systems that handle processes between companies.

**Booking systems and marketplaces** - applications connecting multiple sides of a transaction, with payments and calendars.

These are typically the largest projects we deliver - which is why we start with a **discovery workshop** that validates scope before the first line of code is written. A simpler informational site can be built faster as a [website](https://clavado.pl/en/services/websites), and a live platform can be maintained on [dedicated infrastructure](https://clavado.pl/en/services/hosting).

 06.2 
## What you get.

The full platform build cycle - from discovery workshop through deployment and product development.

 01 
### Discovery workshop

A workshop mapping processes, users and functional requirements of the system.

 02 
### System architecture

Technical architecture design, data model and integration plan.

 03 
### UX/UI Design

Interface design tailored to user roles and workflows.

 04 
### Full-stack development

Frontend and backend built in technologies matched to project scale.

 05 
### API integrations

Connections to external systems - payments, CRM, partner platforms.

 06 
### Admin panel

Tools for managing content, users and system data.

 07 
### Testing & QA

Functional, performance and security testing before deployment.

 08 
### Product development

Iterative feature delivery based on user feedback and data.

 06.3 
## A stack that scales.

We choose technology based on project scale and budget - not the other way around. For most platforms, we work with the stack below:

- Next.js / React ●
- Node.js ●
- PostgreSQL ●
- Supabase / Firebase ●
- Vercel / AWS ●
- Stripe (billing) ●
- REST / GraphQL API ●

 06.4 
## Why Clavado?

Large systems fail not because of code, but because of poorly defined scope. That is why we start with "why", not "how".

**Discovery before development.** A workshop where we map processes, users and integrations - and define what truly belongs in the first version and what can wait.

**An MVP you can grow.** We build a product that first validates the business hypothesis, then scales without a full rewrite - on architecture chosen for real growth.

**Full-stack and end-to-end ownership.** Frontend, backend, database, integrations and deployment on our side - with [infrastructure and support](https://clavado.pl/en/services/hosting) that grows with your user base.

 06.5 
## Frequently asked questions.

  From 3 to 9 months, depending on scope. We typically deliver an MVP within 8–12 weeks after discovery is complete.
