APIs & microservices
An API is a product. If it needs a meeting to use, it is unfinished.
Problem
Service landscapes rot when boundaries follow org charts or blog posts.
Too many services, or one service that is everything. Either way, change is expensive. We draw boundaries around real change rates and give consumers a contract they can trust.
- Microservices adopted as an aesthetic
- Undocumented payloads that only one client understands
- Breaking changes shipped as bugfixes
- No ownership of latency, retries, or idempotency
Capabilities
What this work actually includes.
01
API product design
Resources, errors, pagination, and auth that a stranger can implement against.
02
Service extraction
Peel a capability from a monolith when the boundary is real.
03
Event-driven systems
Topics, contracts, and consumers that fail visibly.
04
Integration layers
The anti-corruption layer between you and a vendor that will change.
05
Developer experience
Docs, sandboxes, keys, and webhooks that reduce support load.
06
Platform reliability
Idempotency, rate limits, tracing, and SLOs as part of the interface.
Technology
Tools we reach for here.
- OpenAPI
- gRPC
- GraphQL
- REST
- Kafka
- RabbitMQ
- Go
- Node.js
- PostgreSQL
- Redis
Approach
How we deliver it.
01
Start from consumers
Who calls this, how often, and what happens when it is slow.
02
Write the contract first
OpenAPI or events as the artefact. Implementation follows.
03
Split only what changes separately
Services are a cost. We pay it when the boundary earns it.
04
Operate the interface
Versioning, deprecation, and dashboards that owners actually watch.
Use cases
Where this tends to land.
Public platform APIs
Partners and customers building on your product.
Internal platforms
Shared services used by several product teams.
Monolith decomposition
A careful extraction, not a rewrite announced as microservices.
Vendor orchestration
A stable interface in front of payments, KYC, messaging, or ERP.

FAQ
Useful questions.
No. We default to a well-structured application and extract services when a boundary is proven — team, scale, or change rate.
