A hacked or broken WordPress site, Meta Conversions API or Shopify numbers that don't add up, an n8n workflow that stopped working. Tell me what is wrong and you get a fixed price before any work starts, from someone who works in your time zone.

About

I am Oscar Villegas, based in Colombia, working on automation, tracking and web development. I spent years on the agency side running Meta and Google ads, so I know a campaign is only as good as its data: if tracking is wrong, every other decision is made blind.

From there I moved into building what makes things work: integrations between platforms, WordPress sites and stores, server-side tracking, and AI agents that handle WhatsApp customer service in production every day.

I work per project, with scope and price agreed before starting, and everything I deliver is documented so you never depend on me to understand it.

How I work

  1. You describe the problem

    Through the form, WhatsApp or email, with screenshots or a Loom video. No mandatory calls.

  2. I send a fixed proposal

    What I will do, how long it takes and what it costs, before asking for access.

  3. 50% upfront, then the work

    You get progress updates and everything is documented.

  4. Delivery, testing, final 50%

    We test with real data and you get a step-by-step handover.

Frequently asked questions

Which countries do you work with?

Mostly the United States, Canada and the United Kingdom, plus Latin America and Spain. I work remotely and bill in US dollars.

What time zone are you in?

Colombia, UTC-5, with no daylight saving changes. That is the same hour as US Central time in summer and US Eastern time in winter, so I work during your business day. UK clients get answers in their afternoon.

What if you can't fix it?

For the fixed-price WordPress fix, if I can't fix it you don't pay. For every other job you get the scope and the price in writing before any work starts, so there are no surprises.

How do payments work?

50% upfront and 50% on delivery, through Payoneer or freelance platforms. Longer projects are paid by phase.

Do we need video calls?

Most of my work is asynchronous and in writing, which also leaves everything documented. Send details, screenshots or a Loom video and I start from there.

Will you sign an NDA?

Yes. That is also why the case studies on this site are anonymous.

Do you use AI in your work?

Yes, as a tool to work faster. The technical judgment, the testing and the responsibility for what I deliver are mine.

Something broken or worth automating?

Tell me what is happening. You get an answer the same day with what I see and a proposal.
