- define the catalog of standard integration approaches - APIs (REST, GraphQL, gRPC), Webhooks, WebView/iframe embedding, SDK -based integration, OAuth -based authentication flows, file -based batch integration.
<\/div>- ensure each approach is extensible and configurable - partners can adjust parameters (auth methods, data fields, event triggers) without requiring code changes to the core platform.
<\/div>- design the partner onboarding architecture - from registration to sandbox to production, with clear gates, automated testing, and self -service capabilities.
<\/div>- architect the data flow patterns - how partner data flows through Kafka event bus, BigQuery analytics, and internal services, ensuring consistency, idempotency, and observability at every step.
<\/div><\/blockquote>2. Coordinate Across All Teams:
<\/div>- Work with backend teams to ensure the integration platform leverages NestJS microservices, Kafka event streaming, and database technologies effectively.
<\/div>- Work with frontend teams to design embeddable UI components, WebView flows, and partner -facing dashboards.
<\/div>- Work with QA to define integration testing strategies - sandbox environments, automated partner flow testing, contract testing.
<\/div>- Work with DevOps to ensure the platform scales on Kubernetes and GCP, with proper monitoring, alerting, and cost management.
<\/div>- Work with product and business to understand partner segments, prioritize integration approaches, and align platform evolution with business goals.
<\/div>- Work with the Lead AI Practitioner to ensure the platform is AI -optimized — AI -readable documentation, AI -testable flows, AI -assisted partner support.
<\/div><\/blockquote>3. Understand All Business Sectors:
<\/div>- Fleet management - how fleet companies manage vehicles, drivers, fuel cards, expenses, and reporting.
<\/div>- Payment processing - PCI -DSS compliance, payment gateways, settlement, reconciliation.
<\/div>- Mobility services - fuel, EV charging, car washing, parking, tolling.
<\/div>- Fintech integrations - how banking and financial platforms embed third -party services into their apps.
<\/div>- E -commerce integrations - how e -commerce platforms offer add -on services to merchants.
<\/div>- ERP / Accounting integrations - how companies like SAP, Datev, or Lexware consume transaction data.
<\/div>- OEM integrations - how car manufacturers embed payment capabilities into vehicle infotainment systems.
<\/div>- Expense management - how services like Pleo, Moss, or Circula process and categorize fleet expenses.
