Senior Database Analyst

Already operating with senior-level responsibilities, formally assumed an active role in coordinating data-related demands, helping organize priorities, delegate activities, track deliveries, and provide technical feedback to the team. Acted as a technical focal point between database, engineering, and business teams, supporting architectural decisions, resolving complex issues, and ensuring alignment between data solutions and operational needs. Led and implemented an end-to-end data solution in collaboration with a Data Scientist for a cash demand forecasting project for a financial institution in Paraguay, covering more than 1,000 ATMs. Owned the full data pipeline, from data collection and preparation to analytical consumption. Designed and implemented the data flow by ingesting and preparing data in Elasticsearch to support model development, enabling efficient access for data science workloads. Prepared the analytical Data Warehouse layer to store model outputs and delivered Power BI dashboards to business stakeholders. The solution enabled more accurate cash replenishment planning for ATMs, reducing operational risk and optimizing armored transport logistics costs. Contributed to continuous improvements in database reliability, performance, and availability for mission-critical payment systems, while strengthening technical standards, documentation practices, and overall team maturity.

Mid-Level Database Analyst

Worked with technical autonomy supporting and evolving mission-critical database environments for payment systems, including card issuance, e-commerce security, and ATM monitoring. Led the administration of PostgreSQL and SQL Server environments across development, staging, and production. Configured PostgreSQL native replication across two data centers and worked with SQL Server Mirroring (2008), later contributing to the migration to Always On after upgrading to SQL Server 2016, ensuring high availability and continuity. Responsibilities included performance analysis, query tuning, bottleneck monitoring, and log management in critical environments. Took ownership of data modeling, designing new data models for modules and applications and evolving existing ones using ERwin Data Modeler, with GitLab-based version control. Implemented version control for database scripts (environment setup and maintenance routines) and Logstash pipeline versioning, improving standardization and reproducibility. Built end-to-end analytics solutions, from transactional data extraction and ETL to domain-oriented, analytics-ready Data Warehouse layers, delivering Power BI dashboards using Power Query (M), dimensional modeling, and DAX. Proposed and implemented monitoring and observability, expanding from databases to applications through log standardization, ingestion via Logstash, storage in Elasticsearch, and visualization in Kibana. Developed Python-based alerts for operational errors, anomalies, and security events, reducing incident analysis time from 1–3 hours to minutes. Led a customer-facing data migration project, upgrading SQL Server 2008 to 2016, accounting for application evolution and data model changes. Created standardized technical documentation, versioned in GitLab, improving onboarding and knowledge transfer, and acted as an informal technical reference, supporting junior analysts.
