About Oriol Omar

For 6 years I've been building systems where mistakes cost money: payment flows processing 6M+ transactions a month, payment processing used by most of Spain's financial institutions.


Now I apply that same discipline to AI.

Most "AI engineers" can build demos; few can take an LLM agent to production with observability, traceability and regulatory compliance.

That's my lane:
• Agent backends and LLM applications in production (TypeScript, Node.js, AWS)


• AI observability with OpenTelemetry — I'm building FleetWatch (fleetwatch.dev), a governance layer for AI under the EU AI Act and GDPR


• Integrating AI into existing products: Next.js fullstack, APIs, payments (Stripe/PSPs), data


What you can expect from me:

Code that reaches production, clear communication with no surprises, and the judgment to tell you when you DON'T need AI.
