Connect to your AI
I will connect your apps with API integrations and automate data flow
Maciej Gryziec
About this gig
Your team copies the same data between the online store, CRM, invoicing, calendar or warehouse? I will connect these tools so the data moves on its own and you do not have to replace software you already use.
Examples:
- a web form creates a client and a task in the CRM
- a new order goes to invoicing and a confirmation email is sent
- a booking lands in the calendar and the team gets notified
- supplier invoices are matched to orders automatically
What you get:
- agreed data flow: which system owns which data
- handling of missing data, duplicates and API outages
- logs and alerts, so failures do not go unnoticed
- short documentation of the setup
I have built integrations with order management systems, invoicing software, e-invoicing (Poland's KSeF), CRMs and email inboxes.
Scope and price are agreed before work starts. Please message me with the apps you use and what should happen between them.

I build custom web apps, CRMs and automations that fit the way your business actually works, from requirements and code to testing and launch. I connect the tools you already use via APIs, cut manual data entry and streamline order handling. Where documents or text need interpreting, I use AI. Recent work: a full CRM linking sales, stock, quotes and invoicing; a 3D PV roof-tile configurator; competitor price monitoring; automated online store audits. Stack: TypeScript, React, Next.js, Node.js, Python, FastAPI, Django, SQL, Docker. Scope and price are agreed before work starts.

FAQ
Do I have to replace my current software?
No. In most cases I connect the tools you already use. If one of them has no API or a very limited one, I will tell you before we start and suggest an alternative.
Which apps can you connect?
Any app with an API, webhooks or file export: online stores, CRMs, invoicing and accounting software, calendars, forms, email, spreadsheets and warehouse systems. Send me the list and I will check it.
What happens when an API changes or goes down?
Integrations log every run and send an alert when something fails, so nothing breaks silently. With the monthly maintenance extra I watch the connections and fix failures for you.
Do you need my passwords to start?
No. To start I only need the list of apps and a description of what should happen. Later I work on a separate technical user or API key with limited rights that you can revoke after the project.
