I am an engineer specialized in Data Governance, High-Performance Architectures, and Service Management, with a strong focus on operations and reliability (SRE).
My vision of technology is forged in the trenches of Production Engineering: working in environments where fault tolerance, resilience, and strict SLA compliance are critical factors for the business.
Professional Experience
Over the course of more than 10 years, I have evolved from pure Business Intelligence solutions development to the comprehensive management of top-tier core platforms.
Site Reliability Engineer & Platform Operations (2023 - Present)
Global Financial Sector
Responsible for the availability and performance of highly critical core platforms in distributed architectures (Cloud, Event-Driven). - SRE & Incident Management: Leadership in the agile resolution of critical incidents (war rooms) and orchestration of distributed technical teams under continuous support models (24/7). - Advanced Observability: Implementation of proactive monitoring strategies for complex systems, drastically reducing operational impact and optimizing detection times. - AIOps & Automation: Adoption and integration of Artificial Intelligence capabilities (LLMs) for triage optimization and technical document management.
Data & Operations Lead (2017 - 2023)
International Banking Sector
End-to-end technical management of the lifecycle and operations of data applications on a global scale. - Technical supervision of deployments, software validation, and change control in high-demand environments. - Definition and tracking of key operational metrics to ensure compliance with service level agreements (SLA). - Ecosystem: Enterprise data integration solutions, relational/NoSQL databases, and visualization platforms.
Data Engineer & BI Specialist (2010 - 2017)
Various Sectors (Finance, Industry, Retail)
Consolidated trajectory in the design, development, and evolution of large-scale analytical solutions and data pipelines. - Architecture and implementation of massive data integration pipelines (ETL) and advanced modeling. - Infrastructure modernization and deployment of comprehensive solutions for regulatory and corporate reporting. - Integration of mission-critical heterogeneous systems, connecting business operations with centralized analytical platforms.

Projects and Architectures
Throughout my career, I have had the opportunity to participate in the design, deployment, and stabilization of critical corporate systems. For confidentiality reasons (NDA), the following projects are presented abstracting the company names and purely internal data.
🚀 Core Architectures and SRE (Service Reliability Engineering)
- Stabilization of Cloud Transactional Platform: Focal point for critical digital operations (Tokenization, 3DS, payment gateways) deployed over a new architecture oriented towards microservices and Kafka streams.
- Impact: Implementation of observability systems (Dynatrace) for proactive alerting, achieving a very significant reduction in direct customer incidents and increasing SLA.
- AI Integration in the IT Support Cycle (Applied LLMOps): Introduction of tools based on Generative Artificial Intelligence into incident resolution workflows.
- Impact: Reduction in triage times, substantial improvement in technical documentation generated post-incident, and optimization of communication dynamics during crises (war rooms).
- Comprehensive Management and Quality (ITIL v4): Assurance and supervision of service transitions and orderly deployments to production in global financial environments, managing to maintain 0% non-compliance in the required certifications.
📊 Business Intelligence and Data Warehousing
- Global B2B Solution (Multinational Printing Technology): End-to-end design and development of an analytical platform based on the Microsoft BI suite.
- Development: Data model (SQL Server), ETL processes (Integration Services) to absorb data from multiple heterogeneous sources (SAP, custom .NET systems, European branches), creation of metadata/cubes (Analysis Services), and dashboards (SharePoint/Reporting Services).
- CRM Ecosystem Migration (Infrastructure/Services Sector): Analytical and technical definition of extraction and loading processes to migrate massive concession and billing systems.
- Development: Executed using Informatica PowerCenter and Oracle 11g, with a strict focus on increasing the quality of the resulting data before the production dump.
- Regulatory Reporting and Banking Datamarts: Maintenance, evolution, and troubleshooting of hyper-critical environments (accounting bases, financial stress) handling massive data volumes under robust technologies (DB2, PowerCenter, Tibco, Cobol).
🏭 Analytics in Industrial Environments
- Production Line Monitoring: Real-time extraction and integration of results coming from programmable logic controllers (PLCs) in chemical/industrial production factories.
- Development: Reconciliation of hardware metrics with the corporate ERP, OLAP modeling, and write-back capability in Excel spreadsheets for rapid manual readjustment of production.
