su.engineering is an independent product & engineering studio in Bilbao, Basque Country. We help companies, system integrators, enterprise teams and research consortia design and ship technically difficult software.
Identity · Privacy · AI · Security · Distributed systems
- Identity & EUDI: wallets, issuers, verifiers, credentials and interoperability.
- Product Engineering: from ambitious technical idea to working product.
- Specialist Partner: senior engineering capability inside your existing project.
We stay small and senior, and build the team around the problem: from one specialist to a full delivery team. Our team brings experience from 30+ enterprise projects, including work before founding su.engineering.
We build what we advise on.
| Product | Status | What it is |
|---|---|---|
| Velum | Live | Privacy infrastructure for everyday AI workflows. Keeps sensitive information from being exposed to AI tools and other external services. |
| OpenKYC | Approaching launch | Reusable identity verification without repeating KYC. Credential-based identity and age verification built on reusable proofs. |
| REM | In development | Shared engineering memory for teams working with AI agents, across developers, repositories and coding tools. |
- heic-web: HEIC support for modern web applications, in browsers where native support is limited or inconsistent.
- react-native-nearby-interaction: Apple's Nearby Interaction framework for React Native apps.
- keycloak-oid4vp: OpenID4VP wallet login for Keycloak, with SD-JWT VC and mDoc verification and X.509, did:web or did:webvh issuer trust.
Engineering notes from actual work: digital identity and EUDI, privacy engineering, AI systems, security, distributed systems and product engineering.
