About

I'm a Data Engineer with 4 years of experience, but I started my career as an Academic Monitor.

I've worked on projects for major companies like PUC Minas, Spotify (BR, LATAM), Heineken, 99, Itaú, Vale, Mercado Livre, MSD/Merck (Global)… all involving architecture, automation, ETLs & analysis.

About Me

Data Partner

Since I started my career, I've been into open-source projects, studying cloud architectures (GCP, Azure) and tech such as Python, SQL, Airflow, Data Factory, MongoDB, PostgreSQL.

I truly enjoy planning projects, making them scalable, discussing and understanding how the project achieves the company's goals.

Outside of work, I like to share experiences:

🖊️ Medium → Data insights
📺 YouTube → Academic projects
🧑‍💻 GitHub → Study + Open-Source projects

Right now, I'm actively exploring roles in high-performance projects, automation, and robust architectures.

Questions?

How do you help companies scale their technical operations?

I establish engineering departments from the ground up and implement scalable architectures. By developing internal libraries and standardizing code, I reduce development time and streamline the onboarding of new technical staff.

What is your approach to handling data for global clients?

I architect high-scale ETL pipelines to automate data ingestion and analysis for major global brands like Spotify and Heineken. To maintain reliability, I build 24/7 monitoring ecosystems that ensure high availability and minimize maintenance hours for critical projects.

How do you use AI and automation to improve business workflows?

I integrate AI solutions and NLP bots into existing workflows to automate customer service and data queries. I also develop specialized toolkits, such as QUATI, to automate repetitive engineering tasks and accelerate the delivery of data solutions.

How do you manage security and compliance across different platforms?

I manage multi-cloud infrastructure while enforcing strict information security policies. This includes ensuring compliance with data protection laws like LGPD through technical documentation, data mapping, and security protocols.

How do you handle data projects involving multiple cloud providers?

I have extensive experience managing multi-cloud infrastructure, specifically GCP and Azure. I implement standardization policies across these environments to ensure consistency, information security, and seamless data integration.

Which technologies do you specialize in for data orchestration?

I specialize in using Airflow and Python to orchestrate complex data workflows. My expertise includes managing databases like BigQuery, SQL Server, and Oracle, ensuring efficient data lifecycles and robust DataOps practices.

Can you work with social media and advertising data (AdTech)?

Absolutely. I have built ETL pipelines to automate data ingestion from platforms like Facebook, Instagram, TikTok, and Twitter. My work often involves competitive analysis and performance insights for brands operating in the digital space.

Do you have experience with Data Visualization and Business Intelligence?

Yes, I develop comprehensive DataViz solutions using Microsoft Power BI and Looker Studio. I also engineer health monitors and 24/7 monitoring ecosystems to ensure that BI dashboards remain accurate and highly available for stakeholders.
