Payment orchestration platform
A multi-tenant platform that unifies online, recurring, phone and in-person payments across several business systems.
Solution Architect at SEIDOR, Valencia
I design architectures that connect enterprise systems, software and payments.
I’m Sergio. For eight years I’ve been turning complex business requirements into systems that hold up in production, across commerce platforms, ERPs and payment providers like Stripe and Adyen.
Build
Distributed systems, APIs and SaaS platforms designed to scale without becoming fragile.
TypeScript, Node.js, Java, AWS
Connect
Integrations across commerce, ERP and PIM, with clear ownership of every piece of data.
SAP Commerce, SAP CPI, Akeneo, Mirakl
Enable
Payment architectures for subscriptions, marketplaces and omnichannel checkout, online and in store.
Stripe, Adyen, Stripe Terminal
Selected work
Four projects that show how I work. Listed by industry to respect client confidentiality.
Event-driven, Kafka, AWS, Stripe
Subscription migration to Stripe Billing
A migration strategy from a legacy provider that kept recurring billing running for every customer.
Marketplace payments integration
A connector between the payments platform and the marketplace, handling payments, KYC, state sync and error recovery.
Product data architecture
ERP, PIM and storefront kept in sync through full and delta flows, with data quality rules at every step.
How I approach architecture
Start from the constraints
Before choosing a technology, I map dependencies, operational limits and integration risks.
One owner per piece of data
Most integration problems are ownership problems. I make the source of truth explicit.
Design for failure
Idempotency, retries, correlation IDs and observability belong in the design, not in the postmortem.
Stay close to the code
I review APIs, read logs and debug production issues. A diagram only matters if the team can build it.
