Your systems
already exist.
We lay the track
between them.

The CRM can’t see the warehouse, accounting never hears about web orders, and the mobile app lives a life of its own. SINTEKHNO designs and builds the connections between your tools — and web and mobile products that exchange data from day one.

WHY AN ATLAS

Map first. Code second.

Most integration problems are cartographic, not technical: nobody knows for sure which system is the source of truth for a customer, a price or a stock level. So every project starts with a map — a diagram of systems, flows and data owners that you receive as a standalone document and can use even without us.

Only once every station and interchange is visible do we choose how to connect: direct API call, webhook, event queue or a nightly batch. The result is integrations you can explain to a new colleague in ten minutes.

WHAT YOU RECEIVE — MEASURABLE DELIVERABLES

Systems map

A diagram of every system involved, flow directions, exchange frequency and the owner of each field.

Data contract

Fields, formats, required flags and conflict rules — a versioned document.

Exchange log

Every sync has an ID, status and an error reason readable without a developer.

Scenario tests

Business scenarios (“order cancelled after payment”) with automated checks.

Runbook

What to do if exchange stops: steps, contacts, restart without data loss.

QUALITY CRITERIA

How we check the track holds

Re-delivering the same message never creates duplicates.
Temporary outage of one system loses no data — exchange resumes from the queue.
Every field has one source of truth, recorded in the data contract.
Access secrets are never stored in code or the browser.
Interfaces meet WCAG 2.2 AA for contrast, focus and field labels.
Pages and apps are checked at 390 px and 768 px widths before handover.
