👤 About Me
I am a Data Engineer with expertise in designing and scaling high-performance data infrastructure and BI platforms. My experience spans large-scale orchestration, event-driven architectures, Kubernetes management, microservices architecture, backend development (Python, Go), and distributed data processing. I specialize in building scalable ETL/ELT frameworks and data pipelines, implementing DevOps practices for data infrastructure, and driving initiatives around data quality, observability, and governance. I have hands-on experience with modern data stacks and data warehouses (BigQuery, dbt, Prefect/Airflow), data modeling and normalization, REST API design, comprehensive testing practices, and AI applications including LLMs and forecasting models. I thrive in collaborative, cross-functional environments and my passion lies in building reliable, scalable data systems that enable data-driven decision-making across organizations.
💼 Work Experience
Data Engineer
- IplanRio
- Rio de Janeiro, RJ
- 2024 - Now
I manage Kubernetes clusters and Prefect orchestration for ETL/ELT operations processing hundreds of GB daily for Rio de Janeiro’s public data lake. I develop microservices in Python and Go with comprehensive testing practices, manage CI/CD pipelines via GitHub Actions and ArgoCD, and implement observability solutions using OpenTelemetry. I built chatbots and AI agents using LLMs to automate internal processes across the city’s public administration. I also manage the full infrastructure stack using IaC tools (Terraform, Ansible), including HA databases (MongoDB, PostgreSQL), Kubernetes clusters, and on-premise VMs, while supporting teams with deployment debugging and troubleshooting.
DevOps / Site Reliability Engineer
- NTT Data
- São Paulo, SP
- 2022 – 2024
I managed Kubernetes clusters and CI/CD pipelines via Azure DevOps and ArgoCD, and implemented observability solutions using New Relic. I developed microservices in Python and managed the full infrastructure stack using IaC tools (Terraform, Ansible, Helm), including Kubernetes clusters and cloud infrastructure. I defined and monitored SLAs, SLOs, and SLIs, managed error budgets, and supported teams with deployment debugging and troubleshooting to ensure system reliability and performance.
Data Analyst
- Abramge
- São Paulo, SP
- 2021 – 2022
My main activity was related to extracting and processing data on the private health sector in Brazil. To do this, I created ETL pipelines using R and Python to process large amounts of data and used exploratory data analysis to produce reports and dashboards for public use. I also managed databases using PostgreSQL and serverless databases such as DuckDB and Apache Arrow. I was also responsible for forecasting relevant indicators using time series econometric tools (mainly VAR-related models).
