Automation & AI agency · Argentina
Automate what your team does by hand
ERP integrations, scrapers, dashboards and AI agents that eliminate manual work. No smoke demos: production systems with real metrics.
01 / Services
What I can automate in your business
Every service comes from a system I already built — running in production today. These aren't packaged products, they're starting points. The version that ends up running in your company is designed around your operation, not the other way around.
ERP & API integrations
I connect your ERP, your online store and your suppliers so they talk to each other. SOAP, REST — whatever your system speaks.
Case: Naccato
Process automation
Syncs, bulk loads, reconciliations: everything your team does by hand, running on its own every 5 minutes.
Case: Naccato
Scraping & data
Data extraction from websites without an API, even behind anti-bot protections. Clean data, delivered where you need it.
Case: Polino Tracking
Dashboards & reporting
Custom panels with login, roles and CSV/PDF export. One screen for your whole operation.
Case: Polino Tracking
AI agents & solutions
Agents that read email, triage reports, investigate incidents and draft replies. AI applied to your real workflow.
Running internally
Advanced e-commerce
WooCommerce and multi-vendor marketplaces at scale: massive catalogs, per-customer pricing, custom plugins.
Case: LibrosActivos
Don't see your case on this list?
Even better. These are the systems I already have running, but I don't work with off-the-shelf products. If a vendor told you that the thing you need “can't be done” or “doesn't come that way,” it usually just means it doesn't fit their packaged software. That's exactly where I come in: I start from your specific problem and build the solution to your measure.
02 / Case studies
Production systems, not mockups
Three real operations running on their own today. Every metric is verifiable.

03 / Process
How we work
Diagnosis
One call to understand your operation and spot where time and money are leaking.
Proposal
Scope, timeline and a fixed price in writing. You know exactly what you get before we start.
Iterative delivery
Weekly releases you can actually try. We adjust on working software, not slide decks.
Ongoing support
Monitoring, logs and improvements. The system stays alive and watched — not abandoned at handoff.

05 / About
You work directly with the person who codes
A specialist, not a vendor.
I'm Sebastián Castelao, a developer and systems integrator based in Argentina. AutopymeAI is my agency, and you work directly with the person who designs, codes and maintains your system: no account managers, no broken telephone, no project passed from hand to hand until it gets lost.
I work with AI agents as my development team. That lets me deliver agency-scale systems with the proximity and speed of a freelancer. It's not a promise: the three cases on this site were built and are operated that way, in production, every single day.
And what people ask me for most is exactly what I enjoy most: custom work. When a packaged system doesn't reach as far as your business needs, that last mile — the part that “can't be done” — is where I work best. I start from your real operation and build around it.
- ERP integrations (SOAP/REST) in production
- Scrapers with anti-bot protections solved
- Marketplaces and catalogs of 100,000+ products
