Analytics Engineer driving automation and scalable telecom data solutions.
BrazilWhat I'm looking for
I am an Analytics Engineer with 12 years in telecommunications and eight years building ETL pipelines, workflow automation, and BI solutions. I focus on turning complex telecom data into actionable business insights through scalable automation.
At TIM Brasil I built automated data pipelines and ETL processes in a Red Hat production environment, reducing processing time by 60% and delivering automated systems that serve 100+ stakeholders. I designed monitoring and alarm systems that improved cross-team collaboration and cut manual inspection time.
I implemented Shell- and Python-based ETL automation and backend tools that saved over US$67,000 in external development and recurring service costs, reduced manual work, and improved maintainability. I also refactored workflows and contributed to governance reporting in an agile team to increase delivery speed and operational efficiency.
My technical strengths include Python, Shell scripting, Oracle and relational databases, Power BI, ETL orchestration, and Linux tooling. I am motivated to apply automation and data architecture best practices to reduce costs, accelerate insights, and scale analytical products across organizations.
