Web platforms and SaaS products.
From the internal system that replaces twenty spreadsheets to the SaaS product you sell to your customers, with everything that demands in security, scalability and measurement.
Business web platforms almost never start from zero: they start by replacing something that already half works, usually a mix of spreadsheets, email and an old system nobody wants to touch. The challenge isn’t technical, it’s migrating without stopping the operation.
When the product is also sold to third parties, a whole extra layer appears: data separation between customers, roles and permissions, billing, usage limits, auditing. These are decisions that are expensive to reverse if taken late, so we settle them in the architecture rather than on the fly.
01 · Web apps / SaaS
What’s included
Multi-tenant architecture
Per-customer data separation, granular roles and permissions, and an audit trail of who did what, solved at design time.
Internal platform or commercial product
Management systems for your operation, or SaaS products with sign-up, plans and recurring billing.
Integrations and migration
Connection to the systems you already use and migration of historical data without cutting the operation.
Security and compliance
Authentication, encryption, verified backups and access logging, with whatever controls your sector requires.
Measurement and scalability
Usage and business metrics from day one, and infrastructure that grows with load without rewriting the product.
02 · Web apps / SaaS
When it makes sense
- Your operation depends on shared spreadsheets nobody fully controls any more.
- You have a custom system that became impossible to maintain or modify.
- You want to turn an internal process you’ve mastered into a product you can sell.
- You need several teams or customers using the same platform without seeing each other.

Frequently asked questions
Yes, and it’s part of the scope from the start. The usual approach is a period where both systems run in parallel until the migrated data is verified to match.
Wherever you decide: public cloud, your own infrastructure or a dedicated server. The accounts are in your company’s name and we hand everything over documented.
If the product requires it, yes: plans, subscriptions, usage limits and recurring billing integrated with the payment gateway you use.
We offer monthly evolution and maintenance plans. We can also hand the platform over documented so your in-house team maintains it, with no dependency on us.
