I will automate your business workflow with nodejs
Marco
About this gig
I build backend systems and connect the tools you're already using (APIs, databases, workflows) so they run without you babysitting them.
3+ years of experience, mostly with startups and a logistics company where manual processes kept breaking as the business grew. Stack: Node.js, TypeScript, Fastify, BullMQ, PostgreSQL, AWS, Docker.
Jobs I usually get:
- Connecting an app to Stripe, a CRM, messaging tools or AI APIs
- Setting up background job processing so heavy tasks don't block the app
- Fixing an integration that's already breaking or unreliable
- Building the backend for a new workflow from scratch
At my last job I introduced some architecture patterns that got adopted across the team and cut delivery time by 15%.
Message me with what you're trying to connect or automate and I'll tell you which package makes sense.

I started my career at a local software house, developing systems for regional businesses as a Full Stack Developer trainee.
After 7 months, I received an opportunity to join a startup as a Junior Software Developer, where I worked with a new programming language and helped refactor an online course platform.
After 11 months, I joined a logistics company, where I worked on refactoring a mobile app and a logistics management system. I stayed there for 1 year and 4 months.
Currently, I am looking for small- to medium-sized projects and freelance opportunities.

FAQ
What information do you need before we start?
A short description of what you want to connect or automate, plus API docs or account access if the project requires it. We can sort out the details in chat before you place an order.
Do you offer ongoing maintenance after delivery?
Not included in the packages above, but I'm open to a separate monthly arrangement if you want someone keeping an eye on the system long term.
What if my project needs an API or service you haven't listed?
Message me first. I work with most REST and third-party APIs, so there's a good chance I can help even if it's not in my stack list.
Which package should I choose if I'm not sure?
Basic is for connecting one service to something you already have running. Standard and Premium are for building a full automated workflow from scratch, including background job processing. Message me and I'll point you to the right one.
Can you fix an integration that's already broken instead of building a new one?
Yes, that's actually one of the more common requests I get. Send me details on what's failing and I'll take a look before quoting anything.
