API Development
APIs that other systems can depend on
We design and build APIs for products, mobile clients, partners and internal teams — with authentication, versioning, documentation and the operational basics production requires.
Definition. API development is the design and implementation of application interfaces: resources, auth, errors, pagination, versioning and the runtime that serves them reliably.
An undocumented endpoint is not a platform
If every consumer needs a Slack message to use the API, you do not have an API. You have a private handshake.
Accidental APIs
Internal routes leak to new clients without contracts or versioning.
Auth as an afterthought
Partner and mobile access get bolted on with a shared key.
No error vocabulary
Clients cannot tell a retry from a bad request from a permission failure.
Capabilities
What we build
Specific delivery, not a vague capability list.
Product APIs
The interface your web, mobile and partners share.
Partner APIs
Scoped access, rate limits and an onboarding path.
Internal APIs
Clear boundaries between services so teams can ship independently.
Solutions
Common implementation scenarios
New product backend
API-first so web and mobile are clients, not competing stacks.
Replace a tangled monolith surface
Extract a stable contract without pretending everything is microservices.
Enable integrations
Give ERP, CRM and automation a clean way in.
How we work
Development process
01
Discovery
We clarify the business problem, current systems, constraints, success metrics and decision-makers before recommending a build.
02
Strategy
We define the product scope, delivery sequence and commercial trade-offs so engineering work maps to a measurable outcome.
03
Architecture
We design the application, data, integration and security model before implementation starts, reducing rework later.
04
UI/UX
We design the interfaces operators and customers will actually use — with clarity, accessibility and conversion in mind.
05
Development
We implement in short, reviewable increments with staging environments and visible progress against the agreed scope.
06
QA
We test functional flows, edge cases, integrations, performance and release readiness before anything reaches production.
07
Launch
We ship with a controlled cutover, monitoring and a clear rollback plan so go-live is an operational event, not a gamble.
08
Support & Optimization
After launch we stabilize, measure and improve — fixing issues quickly and iterating on the features that affect the business.

Industries
Where this service is typically used
Ecommerce
We help ecommerce businesses build Shopify experiences, operational AI, mobile clients and the integrations that keep catalog, orders and inventory honest.
SaaS
We help software companies ship AI capabilities, integration surfaces and mobile clients that respect tenancy, metering and a roadmap you can maintain.
Retail
We help retailers connect commerce, operations apps and back-office systems so availability, orders and exceptions are not a manual sport.
Engagement
How we work commercially
Fixed scope
A defined outcome, timeline and budget after discovery. Best when requirements are clear enough to estimate with confidence.
Dedicated team
A stable product squad that works as an extension of your team across a roadmap, not a one-off ticket list.
Ongoing development
Retained engineering capacity for iteration, integrations, maintenance and new capabilities after the first release.
Consulting
Architecture, vendor selection, AI feasibility, Shopify Plus planning or integration design without a full build engagement.
FAQ
Questions about api development
Contract design, authentication, implementation, tests, observability and documentation. A URL is not the deliverable.
