Three Principles That Guide My Work

Principle 01
Governance is culture, not compliance

Data governance doesn't live in systems — it lives in conversations, agreements, and people's willingness to take collective responsibility for information. I build the cultural conditions for governance to take root and sustain itself beyond any single initiative.

Principle 02
Clarity is the highest form of leadership

In complex, multi-stakeholder environments, the most valuable thing a leader can provide is clarity: clarity of purpose, clarity of roles, clarity of direction. I translate technical complexity into strategic language that enables decision-making at every level.

Principle 03
Sustainable results require installed capacity

The measure of a transformation is not what happens when I'm present, but what continues after I leave. I focus on building organizational capabilities — models, frameworks, roles, and mindsets — that endure and compound over time.

From Technical Expertise to Strategic Leadership

My career has been defined by a consistent challenge: organizations that recognize data as important but struggle to treat it as the strategic asset it actually is. Over 10+ years, I have built the systems, led the conversations, and installed the capabilities that bridge that gap.

"I don't just govern data. I build organizations that know how to govern their own data."

At Compensar — a highly regulated social security and healthcare organization managing sensitive data for millions of members under strict Colombian regulatory frameworks — I built a progressive career from Information Coordinator to Functional Team Lead to Product Owner – Master Data Management. In that journey I designed and implemented governance models, chaired Tactical and Strategic Data Governance Committees, and led the MDM program that established the Golden Record for more than 17 million customer records across Customer, Membership, Contact, and Reference Data domains.

My work spans the full spectrum of data leadership: from technical architecture and MDM implementation using TIBCO EBX, TIBCO Data Virtualization (TDV), and Azure Cosmos DB, to executive stakeholder alignment, governance KPI monitoring, and cross-functional change management. I have built governance operating models, stewardship accountability structures, and data quality controls that reduce enterprise data risk and enable reliable, trusted information for strategic decision-making and regulatory compliance.

Throughout my career, I have been consistently chosen for the most complex, cross-functional initiatives precisely because I bring what technical experts often lack: the ability to hold the strategic vision while managing the operational detail, to earn trust across hierarchical and functional boundaries, and to maintain clarity of direction under conditions of high ambiguity.

Now, as I step into a global leadership role at Bristol Myers Squibb, I bring this full profile to one of the world's most mission-critical data environments — where the quality and governance of master data directly impacts patient outcomes, regulatory compliance, and operational excellence across a worldwide organization.

Five Initiatives That Define My Impact

Customer Data Governance
Enterprise Customer Data Governance Model — Data Owner
Compensar · 2020–2024
Designed and led implementation of the enterprise-wide customer data governance framework using DAMA-DMBOK methodology. Defined data ownership, stewardship roles, quality standards, and policy architecture. Governed the customer data domain across all business units, ensuring consistency, integrity, and regulatory compliance for 17M+ customer records.
Impact: First formalized data governance structure in the organization's history. Cultural shift from data as an IT asset to data as a shared organizational responsibility.
Digital Transformation
PAMC Program — Customer Data Transformation
Compensar · 2022–2023
Led the customer data stream of Compensar's flagship digital transformation program. Aligned stakeholders across business, architecture, technology, and compliance workstreams. Transformed how the organization understood customer data as a strategic priority — not a technical deliverable — enabling cross-functional alignment in a complex, high-pressure environment with multiple simultaneous fronts.
Impact: Customer data repositioned as a strategic organizational priority. Critical cross-functional alignment achieved under program complexity.
Master Data Management
MDM Implementation — Customer 360 Architecture
Compensar · 2021–2022
Governed the master data management implementation across Customer, Membership, Contact, and Reference Data domains — establishing data models, golden record logic, metadata standards, and integration architecture. Defined business rules for data quality, deduplication, and lifecycle management. Coordinated between business stakeholders, enterprise architects, and technology teams to ensure MDM reflected true business requirements, regulatory compliance, and governance intent.
Impact: Single trusted source for 17M+ records across multiple data domains. Foundation for analytics enablement, regulatory compliance, and AI-ready data infrastructure.
Enterprise Architecture
Integrated Customer Architecture & Data Layer
Compensar · 2021–2023
Directed the implementation of an integrated customer architecture and enterprise data layer using TIBCO EBX (MDM platform), TIBCO Data Virtualization (TDV), and Azure Cosmos DB. Established the technical and governance foundation for organization-wide customer modernization, enabling scalable master data management and integrated data interoperability across all business units.
Impact: Scalable MDM architecture enabling the Golden Record for 17M+ customer records. Foundation for analytics, AI enablement, and digital transformation.
Information Governance
Foundational Information Governance — Operational Excellence
Compensar · 2015–2020
Built the foundational information governance capabilities at Compensar from the ground up: implemented data quality initiatives, standardized governance practices across business units, ensured regulatory compliance and reporting integrity, and established the organizational discipline around data management that enabled the organization's subsequent strategic transformation. This foundational work created the conditions for every governance initiative that followed.
Impact: Organizational data management culture and governance discipline that became the launchpad for enterprise-wide MDM and digital transformation.

Three Moments That Shaped My Leadership

Moment 01
When I Realized Governance Is a Human Problem
Early in my career, I built a technically rigorous data governance framework — complete with policies, standards, and procedures. It was architecturally sound. And it failed to take hold. The data owners didn't feel ownership. The stewards didn't understand their role. I realized that I had built a system for data, but not a system for people. That failure became the foundation of everything I've built since.
"The best governance framework is the one people actually use."
Moment 02
Holding Direction When Everyone Wanted to Stop
In the PAMC program, there was a point where the complexity — multiple simultaneous workstreams, shifting priorities, competing stakeholder agendas — made it tempting to narrow scope and declare partial success. I chose to hold the broader vision. Not from rigidity, but from clarity of purpose. I had to have individual conversations, address fears, and rebuild alignment. The program delivered. That experience taught me what leadership under genuine pressure actually requires.
"Clarity of purpose is what allows you to bend without breaking."
Moment 03
The Day a Business Leader Said "This Is Our Data"
After 18 months of patient work on cultural change around data ownership at Compensar, a senior business leader — not a technology person — stood in a governance committee meeting and said: "This is our data. We are responsible for it." It was a single sentence, but it represented the entire shift I had been working toward. That moment clarified for me that the real measure of success in data governance is not the framework — it's the moment when the organization internalizes ownership.
"Success is when people stop saying 'the IT data' and start saying 'our data.'"
