Architecture

Unified API gateway built on Next.js API routes with tRPC or GraphQL Yoga, providing typed contracts generated from upstream ERP/CRM/PIM/payments specs via Zod and codegen. Event-driven sync through Inngest handles real-time data flow with retry logic and dead letter queues, while Supabase manages integration state and Redis provides edge-level caching with TTL-based invalidation. Full observability via correlation IDs, structured logging, and Sentry integration traces every request across system boundaries.

Dónde fallan los proyectos empresariales

Here's the thing about most enterprise stacks we inherit -- they're held together with undocumented point-to-point integrations between the ERP, CRM, PIM, and frontend Nobody wrote down how they connect. Nobody drew the map. So when a developer in Atlanta updates a field name in SAP, a Shopify storefront in production starts throwing 500 errors at 2am, and your team spends four hours figuring out which of the six systems actually broke first. That's the cascading failure problem. And it's not rare -- it's basically the default state of any stack that's grown organically over three or four years without a dedicated integration layer. The real kicker is there's no debugging path. You're just... guessing. Checking logs in five different systems, correlating timestamps manually, hoping someone remembers why that webhook exists. We've seen revenue-impacting outages drag on for six-plus hours simply because nobody could answer "where does this data actually come from?"
Batch sync jobs running on cron schedules are quietly killing conversions Your product pricing, inventory levels, and customer data can be hours -- sometimes days -- out of date on customer-facing pages. And honestly, that gap costs real money. A customer in Chicago sees a price that expired yesterday, buys it, and now you've got a support ticket, a margin problem, and a refund to process. We've seen stale inventory data alone generate hundreds of tickets a month on mid-size catalogs. Cron-based sync felt reasonable in 2015. In practice, it just doesn't hold up anymore.
No observability across integration boundaries means when something looks wrong on the frontend, nobody actually knows which system is lying Is the price wrong because the ERP didn't sync? Because the PIM overwrote it? Because the caching layer is serving a stale response? There's no source of truth anyone can point to with confidence. So debugging becomes a group archaeology project -- pulling logs from three different teams, none of whom can see each other's systems. That's not a technology problem. It's a structural one.
Frontend teams shouldn't be writing integration code But without a proper gateway layer, that's exactly what happens -- your React developers end up reverse-engineering Salesforce responses and hand-rolling data transformations just to ship a product page. Feature velocity drops 40-60% fast. We've watched teams in that situation where the frontend lead was spending more time reading ERP documentation than building UI. That's expensive, demoralizing, and completely avoidable.

Qué entregamos

Typed API Gateway

We build a unified GraphQL and REST gateway with TypeScript types auto-generated directly from upstream system specs. So your frontend team consumes one consistent, documented interface -- doesn't matter if the backend is SAP, Salesforce, Akeneo, or some legacy REST API from 2011. The complexity gets absorbed at the gateway layer. Your developers just see clean, typed endpoints that behave predictably. No more digging through Confluence pages trying to figure out what field SAP actually returns for a product's base price. It's all handled before it ever reaches them.

Event-Driven Sync Engine

Real-time data propagation runs through Inngest workflows with automatic retry, dead letter handling, and guaranteed delivery. Batch cron jobs are gone. So is the data staleness they cause. When a price changes in your ERP, that update moves through the pipeline immediately -- not at 3am when the next sync window opens. And honestly, once you've seen how clean this is compared to debugging a failed cron job at midnight, you won't miss the old way at all.

Runtime Schema Validation

Zod schemas sit at every integration boundary, and they catch upstream changes before anything broken reaches the frontend. So when a vendor updates their API and renames a field -- which happens constantly -- you get a logged, alerted incident instead of silent data corruption spreading through your catalog. It's not glamorous. But it's the difference between catching a schema drift at 9am and discovering it cost you conversions at 9pm. We've seen that second scenario play out too many times to leave this part to chance.

Edge Caching with Smart Invalidation

Redis and Vercel ISR caching with event-driven invalidation gets you sub-second page loads without sacrificing freshness. TTL strategies are tuned per data type -- pricing refreshes in seconds, product descriptions in minutes. You're not picking between fast and accurate. You get both, because invalidation fires when the data actually changes rather than on some arbitrary timer. That distinction matters more than most teams realize until they've burned a week debugging stale cache serving incorrect prices to real customers.

Full-Stack Observability

Correlation IDs trace every request from the browser through the gateway all the way to each upstream system. Dashboards show sync lag, error rates, and data freshness per integration -- so when something's off, you know exactly where the chain broke. Automated alerting and runbooks mean your on-call engineer isn't starting from scratch at midnight. There's no "check everything and hope" anymore. You open the dashboard, see which integration is misbehaving, and follow the runbook. That's it.

Graceful Degradation and Circuit Breaking

Per-integration circuit breakers serve cached data with staleness indicators when upstream systems go down. SAP's in a maintenance window? Your site keeps serving product pages. A third-party logistics API times out? Checkout still functions. We define the degradation strategy up front so "upstream outage" stops meaning "site outage." And look -- every system goes down sometimes. The question is just whether you've decided in advance what happens when it does, or whether you're making that call under pressure at 11pm.

Preguntas frecuentes

¿Cómo manejas los cambios de esquema en sistemas ascendentes como SAP o Salesforce?

Cada límite de integración ejecuta esquemas de validación Zod que detectan cambios estructurales en tiempo de ejecución antes de que algo roto se propague hacia abajo. Además, generamos tipos TypeScript directamente de especificaciones de API ascendentes, por lo que la deriva de esquema aparece como un error de tiempo de construcción, no como un incidente de producción que descubres de un cliente. Las funciones de transformación del gateway hacen el trabajo pesado de aislar cambios ascendentes de lo que tu frontend realmente consume. Tus componentes React nunca ven una respuesta cruda de SAP. Nunca.

GraphQL o REST — ¿cómo decides cuál usar para cada integración?

GraphQL tiene sentido para consultas relacionales y de lectura intensiva — catálogos de productos, perfiles de clientes, agregación de contenido — donde los equipos de frontend necesitan obtención flexible de datos sin sobre-obtener recursos completos. REST sigue siendo la opción correcta para puntos finales transaccionales que necesitan garantías de idempotencia: captura de pagos, envíos de pedidos, receptores de webhooks. La mayoría de proyectos empresariales que construimos honestamente usan ambos. Pero están unificados detrás de una única puerta de enlace tipada, por lo que tu equipo de frontend no tiene que importarle qué protocolo usa una operación dada bajo el capó.

¿Qué pasa cuando un sistema ascendente se cae?

Los cortacircuitos y degradación elegante se configuran por integración, no como un fallback de manta. Los datos en caché siguen sirviendo lecturas con indicadores de antigüedad para que los clientes no estén mirando páginas rotas. Las colas de eventos almacenan escrituras con reintentos automáticos y manejo de letra muerta para que nada se pierda durante una interrupción. Y los paneles de observabilidad revelan exactamente qué está caído y qué está afectado, sin más "algo está mal, verifica todo". Aseguramos las estrategias de degradación durante el diseño de la arquitectura, no durante un incidente a las 2am.

¿Cómo garantizas la consistencia de datos entre sistemas ERP, CRM y PIM?

Aquí está la clave que la mayoría de equipos se saltan: propiedad clara del sistema de registro para cada entidad de datos. Los precios viven en el ERP. Las descripciones de productos viven en el PIM. Los registros de clientes viven en el CRM. La puerta de enlace impone esas reglas de propiedad programáticamente. La sincronización impulsada por eventos mantiene los espejos descendentes frescos dentro de segundos. Y la lógica de resolución de conflictos se define durante la fase de arquitectura, no se deja a quienquiera que esté de guardia cuando dos sistemas no están de acuerdo sobre un precio.

¿Puede esta capa de integración soportar nuestro frontend existente o requiere una reconstrucción?

La puerta de enlace expone puntos finales estándar de GraphQL y REST, por lo que cualquier frontend puede consumirlos — Next.js, React, Vue, incluso una aplicación heredada renderizada en el servidor que ha estado funcionando desde 2014. Típicamente conectamos la puerta de enlace a tu frontend existente primero mientras construimos nuevas páginas Next.js en paralelo. La migración es incremental. No necesitas una reconstrucción completa para comenzar a obtener acceso a API limpio y tipado a tus sistemas backend. Ese es más o menos el punto completo.

¿Cómo se ve la observabilidad en toda la capa de integración?

Cada solicitud obtiene una identificación de correlación que se rastrea a través de la puerta de enlace en cada llamada de sistema ascendente. Registramos tiempos de respuesta, tamaños de carga útil y tasas de error por integración — no solo métricas agregadas, sino desgloses por sistema. Los paneles personalizados muestran la frescura real de los datos: qué tan antiguos son tus precios de productos ahora, cuánto tiempo desde el último sincronismo de Salesforce. Las alertas se activan en umbrales de retraso de sincronización, picos de tasa de error y degradación de latencia ascendente. Cada alerta tiene un runbook adjunto. Por lo que tu equipo sabe qué hacer, no solo que algo está mal.

¿Cuánto tiempo toma un proyecto típico de arquitectura de integración empresarial?

Once a dieciocho semanas desde auditoría hasta entrega en producción — el rango depende de cuántos sistemas estamos conectando y cuán complicada se vuelve la lógica de transformación. Pero tu equipo de frontend no está esperando hasta la semana dieciocho para ver algo. Las primeras API tipadas están disponibles dentro de seis semanas. Fasamos la entrega deliberadamente para que tus desarrolladores comiencen a construir contra datos reales temprano. Sin lanzamiento de big-bang. Sin un apagón de seis meses donde nada se envía.
