Overview
Criptan is a Spanish fintech app for buying, holding and earning yield on Bitcoin, Ether and stablecoins. It is registered with Banco de España, holds a MiCA license and serves retail and business customers through its iOS and Android apps.
Criptan is NYT87’s main client. José Miguel works with the Criptan team as a senior software engineer on the backend services behind the product. The codebase is private, so there is nothing to browse here, but the engagement is live and ongoing and we are happy to walk through the work in a conversation.
What we do
- Backend services. Design, build and maintain the server-side systems the app depends on, from APIs to the services that handle customer operations.
- Reliability in a regulated product. Work inside a fintech’s constraints: correctness, auditability and predictable releases matter more than speed for its own sake.
- Embedded in the team. Remote-first collaboration inside Criptan’s own workflow, tools and release process, with documented decisions and clear ownership.
Why it matters
A regulated financial product is the kind of system NYT87 is built for: one where weak execution, unclear ownership or an expensive rewrite later is not an option. The engagement is the clearest example of how the studio works with a product team over the long run.
