Why your GA4 migration is really a governance project.
Most migrations fail silently. Here's what to watch for, and how to set up naming and ownership rules before the first tag fires.
Read the piece →I'm Ivan Jimenez — a marketing analytics engineer and cofounder of DataScrive. I build the measurement systems global brands use to understand their customers, cut waste, and grow with conviction.
For over five years I've helped brands move from reporting dashboards to decision systems — instrumenting the data layer, modelling what matters, and translating numbers into revenue and business impact.
Helping business grow by leveraging their data
I began in paid media and digital marketing, running campaigns and maximizing the ROAS. I was good at it — but I kept getting distracted by something underneath every dashboard: is this number actually true? And what is it really telling us?
That question pulled me in. I started implementing tracking instead of just consuming reports. I began uncovering the gap between what teams thought was happening and what the data actually said. I built systems where there used to be guesswork. And somewhere along the way, I fell in love — not with the tools, but with records themselves.
Think about it: the oldest writing humans ever produced wasn't poetry or scripture. It was accounting. Clay tablets from Mesopotamia, over 5,000 years old, logging transactions — including workers being paid in rations of beer (which I'm also passionte about). Before we wrote stories, we wrote receipts. Records are how civilization remembers, settles, and trusts itself. Every data system I build is part of that same lineage: someone pressing a stylus into clay so the next decision can be made on something real.
That's the work I do now — designing measurement systems, building data foundations, and turning messy digital exhaust into something a business can actually bet on. I've done it for Pizza Hut, Isobar, Gillette, Banco de Loja, Bancolombia, Good Will, and dozens of others.
What I care about most: clean data flows, honest measurement, and the craft of translating a business question into a number you can bet on.
From first tag to last dashboard, I work across the full analytics stack — but the deepest value lives where these disciplines overlap.
Measurement plans aligned with business goals. Data-layer design, event taxonomies, and governance that survive reorgs and replatforms.
Client- and server-side GTM builds with clean hand-offs to engineering. Migrations from legacy tracking to modern, first-party architectures.
From raw exports to queryable marts in BigQuery. Models designed for the questions teams actually ask — not just the ones the tool defaults to.
Looker Studio and Tableau dashboards with a point of view. Built to drive decisions, not to impress stakeholders with chart density.
Applying AI where it actually helps: automating reporting, enriching data, accelerating analysis.
Cookie consent, server-side first-party tracking, and GDPR/CCPA-ready architectures that keep data clean without sacrificing signal.
Case studies available on request. NDAs redacted where needed.
Implementing web and app measurement on GA4, Firebase and GTM across global markets. Leading tracking migrations to modern e-commerce platforms, shipping Looker Studio dashboards tied to KPIs, and supporting markets with the data quality and insight they need to operate.
End-to-end digital analytics projects for 20+ international clients. Measurement plans, server- and client-side GTM, Google Marketing Platform and Cloud integrations, and insight-driven solutions sustaining 95%+ client satisfaction.
Collected 2M+ first- and third-party data points enriching CDP profiles. Client-side tracking, consent management, and decision-ready dashboards across 15+ enterprise clients in LatAm and the US.
Led the digital unit: strategy, paid media (ROAS 4–20×), web analytics, and B2B/B2C commerce builds. The operator years that still inform how I measure.
40+ GTM / GA / Looker Studio deployments for clients including Isobar, Gillette, Constructora Bolívar, SrInmobiliario and Banco de Loja. Campaigns, storefronts, and measurement — shipped.
Short, opinionated pieces on analytics engineering, measurement strategy, and the quiet craft of making data trustworthy.
