• I ship products end to end. I designed, built and operate a production SaaS for music distribution used by 150+ independent artists, including payments, CI/CD security and AI-powered workflows.
• I've done this before without code. I built and sold an e-commerce business, founded a live-music brand, and produced TV formats including Big Brother (Spain).
• I'm going deep on fundamentals. At 42 Madrid I work in C/C++, Unix systems, concurrency, networking and containers, all through peer-reviewed projects.
• I translate between worlds. I've spent 5 years teaching tech and business, and 20+ years working with clients, brands, artists and public administration.

Looking for: Product Engineer · Full-stack Engineer · Founding Engineer roles in SaaS, creator tools, internal platforms or applied AI.

A music distribution & marketing SaaS for independent artists in Spain and Latin America. I'm the sole engineer: product, architecture, code, deployment and support.

Engineering highlights

• Payments & credits on Stripe: idempotent webhook handling, retry logic and an audit trail, because money flows can't have "mostly works".
• Security in CI/CD: automated OWASP ZAP scans in GitHub Actions on every deploy.
• AI-assisted marketing flows: Claude API integrations that generate campaign assets for artists.
• Designed for operations: support tooling, permissions, edge cases and traceability, beyond the happy path.

➡️ Architecture & engineering decisions · The codebase is private, and I'm happy to walk through it in an interview.

• Odoo (Python): custom modules for invoicing, treasury, accounting and tax processes.
• Verifactu: e-invoicing integrations for Spain's new anti-fraud invoicing regulation.
• n8n: automations connecting CRM, email, campaigns and reporting.

• Product 0→1: I turn vague needs into flows, MVPs and products people actually use.
• Clients & stakeholders: I've negotiated brand integrations for national TV, supported 150+ artists, and sold B2C and to public health administrations.
• Team coordination: I've run TV production crews, concerts, festivals, tours, and the collaborators in my own companies.
• Teaching & communication: I've taught digital marketing, business, programming and nutrition for 5 years. I explain technical concepts to non-technical people, and business needs to engineers.
• International: I spent four years between Spain and the US touring with artists and designing for an independent record label.

Education: 42 Madrid (in progress) · Master's in Audiovisual Production · Studied Audiovisual Communication & Multimedia (Universidad Francisco de Vitoria) · Music Management · Higher VET in Dietetics · Certified Personal Trainer

• Full ownership: problem → implementation → deployment → iteration.
• Listen before building: I talk to users to decide what's actually worth building.
• Design for real operations: I plan for exceptions, support, permissions and auditability.
• Explain the why: I write docs and PRs that non-engineers can follow.
