What this covers
APIs and integrations that connect your screens, data and outside services reliably.
Tools
Node.js, GraphQL, PostgreSQL, AWS. The exact stack depends on what you already use.
Where it helps
- Clear agreements between your app and server on what each request sends and returns.
- Input checks, access checks and predictable errors.
- Integration docs and repeatable tests for the main flows.
We agree what “done” means before work starts.
What you get
- Endpoint and integration requirements
- API implementation and data validation
- Login and permission checks where needed
- Integration checks and API handover documentation
The final list depends on the agreed scope. The estimate and schedule follow from it.
Data and security
We agree on login and access rules, how long data is kept, where keys are stored, and who handles releases. Early reviews use sample data, not real records.
How I work on it
Discovery, then scope and what “done” means, then design, build, testing, release prep and any agreed support.
What helps me get started
- Existing API documentation and a test environment
- Required integrations and sample synthetic payloads
- Data ownership, access rules, and hosting requirements
A short outline is enough for a first call. Please send sample data, not real records or passwords.

Can you work with our existing backend?
Yes. I can build or connect one workflow inside your current setup, with responsibilities agreed with your team.
Do you need production access at the start?
No. An outline and some sample data are enough to scope the work. We agree on a safe way to share access later.
