I'm Darta.
I solve problems with software.

Mid-level full stack developer focused on systems and automations. I build systems connected to the tools a company already uses and turn manual work into routines that run themselves. And I know marketing: SEO, Google and Meta.

Automation

SUPERPOWER Nº1

Manual work becomes a routine that runs itself.

I look at repeated work and turn it into an automatic flow: n8n, AI agents and scripts that do the job while the team focuses on what matters.

Integrations

SUPERPOWER Nº2

Systems that talk to the outside world.

I build systems full of external connections: WhatsApp, marketplaces, webhooks and third party APIs. Leading the CRMillion team, I kept a system with more than 500 users running smoothly.

SUPERPOWER Nº3

A developer who knows marketing.

I've worked with SEO and with Google and Meta tools, on paid and organic traffic. I build for the people who need to find, click and convert.

SUPERPOWER Nº4

From problem to a live system.

I take a real pain and deliver the working system: Ovis, a sheep farming management app, and Favo OS, the internal system of a creative studio with a client portal.
