An independent studio means one person who understands your needs, designs the solution and writes the code.

One point of contact

You talk directly with the person who designs and codes.

Short iterations

Testable versions early, adjusted with you as we go.

Readable code

Modern technologies, documented code that is easy to take over.

Support after delivery

Maintenance and new features, so you're never left on your own.

The method

From the first conversation to production, every step is scoped and visible.

01

Scoping

We clarify the need, real-world usage and constraints.

02

Prototype

A working version to validate the direction before investing.

03

Development

Short iterations, careful code, regular check-ins.

04

Delivery

Production release, documentation and support.

Frequently asked questions

The essentials before you start. Another question? Write to me.

What kinds of software does Kaleido Lab build?

Desktop applications (Windows, macOS, Linux), iOS and Android mobile apps, APIs and back-ends (REST, real-time, integrations), and tools that build in artificial intelligence: LLMs, agents, RAG and automation.

Who will I be working with?

Directly with the person who designs and codes your software. Kaleido Lab is an independent studio: a single point of contact, from the first idea to production.

How does a project work?

In four steps: scoping your needs and constraints, a working prototype to validate the direction, development in short iterations with regular check-ins, then delivery with production release, documentation and support.

Does my project have to use AI?

No. AI is offered when it really helps: automating a task, searching your documents, analyzing content. It can also run locally, on the device, when data privacy requires it.

What happens after delivery?

Support continues: maintenance and new features. The code is written with modern technologies, documented and easy to take over.
