Custom API Development

Sooner or later it happens: a partner asks “do you have an API?”, an app needs to read the catalog, a supplier needs to update price lists. Manual exports and direct database access don’t scale. I design tailor-made APIs that expose your data securely, documented and under control.

The problem

Data locked inside ERPs and databases reachable only from the inside, exchanges with partners via email and CSV, every new integration starting from scratch. Without a single access point, every request becomes a project.

What I build

  • REST or GraphQL APIs designed on your domain: products, orders, customers, documents.
  • Authentication and permissions: OAuth2, API keys, roles for partners and applications.
  • OpenAPI documentation and a test environment for integrators.
  • Versioning, rate limiting and usage monitoring.
  • Webhooks to notify external systems of events in real time.

Technologies

Symfony + API Platform, Node.js or Golang for high-performance services, PostgreSQL/MySQL, OpenAPI/Swagger, OAuth2/JWT, caching and CDN where needed.

Use cases

  • Manufacturer: catalog and availability API for resellers, replacing Excel price lists.
  • Ecommerce: orders API for the dropshipping logistics partner.
  • Corporate group: a single API on top of multiple ERPs feeding apps and BI.

Frequently asked questions

The API is the orderly access door to your data: it lets ecommerce, apps, partners and suppliers read and write information without direct database access or manual exports.
Standard authentication (OAuth2, tokens), per-client and per-resource permissions, rate limiting and access logs: each consumer sees only what it's supposed to see.
Always: browsable OpenAPI/Swagger documentation and a test environment. A partner must be able to integrate without writing to you every day.
