Service
I connect systems that were never meant to talk to each other. ERP with an online store, an internal app with accounting, a third-party platform with the database you have always had. The goal is always the same: enter the data once and let it reach wherever it needs to go.
Documented, authenticated and versioned REST services on .NET or Node.js.
Idempotent processes: a retry never duplicates. Data stays consistent on both sides.
Error logging, automatic retries and alerts, so a failure is not discovered a month later.
Transfers between systems with upfront validation, a difference report and the ability to re-run.
When two systems do not talk, someone becomes the bridge. That someone exports a spreadsheet, reviews it, imports it and fixes what broke. It costs hours every week, and every manual step is a chance for an error that will surface later as mismatched stock or a wrong invoice.
A proper integration does not just save that time: it removes an entire class of errors. The data exists in one place and propagates; there are no two versions of the truth to reconcile.
Almost always. Without an API you can work against the database, exchange files, or scheduled processes. Less comfortable, still viable.
