About this gig

Need two systems to talk to each other? I'll connect them 

via API or webhook so data flows automatically without 

manual work.


I handle:

- REST API integrations between any two platforms

- Webhook setup and processing (receive, parse, forward)

- Data transformation and mapping between systems

- Scheduled data sync (polling, cron-based)

- Error handling and basic logging

- Connections to tools like Notion, Airtable, Google Sheets, 

 Slack, Telegram, CRMs, custom backends...


What you get:

Working integration (code or workflow, depending on stack)

Short documentation explaining the data flow

1 revision included


How it works:

1. You describe the two systems and what data should move

2. I confirm scope and delivery time

3. I build, test and deliver with documentation


I prefer well-scoped projects.

The clearer the brief, the faster the delivery.


Note: Part-time availability (evenings and weekends, CET).

Typical delivery 2-4 days depending on complexity.
