Hi, I'm Maria. I've spent 9 years in tech: first as a fullstack developer, then the last 4 as a paid media specialist for international agencies. I've worked with agencies in the US, Sweden, the UK and Spain. Every market plays by its own rules, and I know how to move a strategy from one sector to another without breaking it.
I'm based in Madrid and work remotely with agencies across Spain, the rest of Europe, Latin America and the United States. In Spanish or English, and I shift my hours to the client's time zone, East and West Coast included.
I spent five years as a developer before this. I write Google Ads scripts, optimise the landing pages and handle the technical side without passing it to another supplier.
Every dollar counts. I review spend weekly and move budget towards what performs.
I recommend only the channels that will work with your budget. If one doesn't fit, I'll say so.
My philosophy: work side by side with my clients, honestly and efficiently, to grow their business in a sustainable and profitable way.

From one inherited campaign to 13 across three funnel stages
I inherited an account running a single conversion-only campaign with one mature creative. I rebuilt it into a full funnel (awareness, consideration and conversion) across static, video, carousel, document and thought-leader formats. Then I rewrote the lead form and restructured the creative. Form completion went from 1.6% to 6.1% in three weeks. The cheapest campaign delivered leads at $163 CPL, against an account average near $970.

Total campaign budget
A two-channel strategy for an internship programme with both B2C and B2B goals: Google Ads to capture high-intent searches from students and graduates, LinkedIn Ads to reach HR and talent managers at companies. I built a dual landing page strategy, one per audience. We started with exact-match keywords to protect traffic quality, then broadened the top performers once validated. I implemented target CPA and excluded underperforming devices and age brackets. The result: 29 conversions at a $28 CPL on a $1,300 total budget.
