integrations
Retries, idempotency and clear errors, so nothing gets lost.
service · Node.js
The glue between your tools, written properly.
Webhooks that drop events, integrations held together by scripts, marketplaces that need orders synced in real time. I write the Node.js and TypeScript services that keep data moving.

questions people ask
Before you book.
Can you work with our existing API?
Yes. I start by documenting what exists, then extend it without breaking current clients.
Serverless or servers?
Whichever fits: AWS Lambda for spiky work, long-running services where you need queues and state.
Do you write tests?
Always. Integrations fail at the edges, so the tests focus there.
