My background is in content and digital marketing. The part that stuck is the machinery underneath: tracking, data, reporting, automation. Now I'm focusing on GTM engineering, because it loops it all together across marketing, sales, and product: the technology, strategy, and scale that make businesses grow. Six years owning analytics and web operations at SeeScan, a B2B hardware manufacturer (three brand sites, 250K+ annual sessions, 92% organic). For Los Bravos, a cross-border real estate developer, I built the full GTM operation solo and proposed, priced, and closed the engagement myself. Through Digito, I ship marketing, GTM, and analytics tools. Separately, I build independent data products and finance/investing systems. Bilingual EN/ES, raised on the US-Mexico border.
Los Bravos | Lead Intelligence System
A go-to-market operating system, built solo for a cross-border industrial real estate development firm with no existing systems: pipeline infrastructure for high-value, long-cycle deals. A 6,218-record prospect database (124% of target), a custom CRM-style dashboard, ICP filtering and account-based prospecting, 59 account-intelligence packets with expansion signals and outreach angles, AI-assisted enrichment and search (NLP via Groq), and automated weekly GA4 reporting, all handed off with documentation. Delivered 104% of contracted targets, on an engagement I proposed, priced, and closed myself.
Client prospect data is confidential and never published. The linked packet is a sanitized sample built on a fictional company with synthetic data, to show the format and methodology.

The multi-site GA4 reporting pipeline I run at SeeScan, productized: it pulls GA4 over the API and generates the reports leadership uses for budget and ROI decisions: traffic, engagement, channels, devices, and intent paths, with anomaly alerts. The live page is a sample; running it on your own data needs a GA4 service account.
