API Platform Engineer

Once your APIs have external consumers (partners, third-party developers, internal teams across the org) you need a real API platform: gateway routing, versioning discipline, rate limiting, and documentation that lets consumers self-serve instead of filing a support ticket. We build that platform layer, including developer portal setup, so growing your API surface doesn't mean growing your support burden proportionally. This is for teams whose API consumers keep breaking on undocumented changes, or who need rate limiting and versioning before opening the API up more broadly. You get a gateway and portal your API consumers can actually work with independently.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

1
Audit current API consumers, versioning practices, and rate-limiting gaps to find where breakage is happening.
2
Build a pilot gateway configuration for one API surface, testing versioning and rate limits against real traffic.
3
Review the pilot with API consumers or your team to confirm the developer experience actually works.
4
Roll out the gateway and developer portal across your full API surface with monitoring for consumer impact.
