Software, shaped grain by grain.

Product engineering studio from Uruguay

We take web and mobile products from the first idea to production, as a focused project or inside your team. We've built design systems, platforms and MVPs for US companies, and we check every change before it ships.

Services

A new product, or a better next version

Tell us what you want to build or improve. We can take it from scratch to production, or join the team you already have.

  1. Products, end to end

    From the first conversation to production: scope, interface, backend and release, owned by one team.

  2. Inside your team

    We join your codebase and your process and work with you directly, in hours that overlap with the Americas.

  3. Interfaces and design systems

    Accessible components, design systems other teams build on, and interfaces that stay fast with a lot of data.

  4. Agent workflows for your team

    Coding agents set up in your repository, with the instructions and review steps that keep their work checkable.

Our projects

Software we wanted to build

Our own products, built end to end. Most are live: open them, try them and read the code.

  2. App
  3. Course

  6. Demo

Experience

Experience your product can build on

More than five years building software for US companies, from inside their teams.

  1. Inside US product teams

    We started shipping React interfaces for US clients through a Montevideo software factory.

  2. Taking on whole pieces

    A web frontend carried to its MVP launch, a platform's frontend and its backend in production, a design system to its first release.

  3. What other teams build on

    Most recently, the React library Meraki teams build with, a whole team's agent workflows, and our own products.

How we work

How a project runs with us

Focused projects or long-term work, in English or Spanish, from Uruguay (UTC−3).

  1. Start with a conversation

    We meet to understand what you need, who will use it and what already exists.

  2. A quote you can plan with

    A scope and a quote split into stages, so you know what each step delivers before it starts.

  3. Progress you can open

    Working software early and often, on a link you can try, not only in status reports.

  4. Agents build, we decide

    Coding agents research, implement and review under our direction. Every change passes tests, CI and an independent review before it reaches you.

The studio

Two brothers from Rocha, one studio

We're Baltazar and Felix Andersson. We learned to code young and spent the last years building for US companies before starting Médano Labs together.

  1. Felix Andersson

    From an MVP launch to a design system used across Cisco Meraki, and his own apps built end to end, interface to server.

  2. Baltazar Andersson

    Started in frontend and grew into the backend in production and into owning features through release. He likes taking on unfamiliar parts of a system and leaving them working.

  3. Our name comes from the dunes

    Médano means dune. Ours are the ones of Cabo Polonio and Barra de Valizas, on the coast of Rocha where we come from.
