Data Engineer & AI Consultant

VF. Insights

Data Engineering & AI Consultant, specializing in designing and building scalable pipelines, ETL/ELT systems, and web crawlers that turn fragmented data into reliable, AI-ready foundations. My work spans Snowflake, Databricks, Python, and Scala.

01. About Us

I'm Vinicius, a Data Engineering & AI Consultant based in Brazil. I help organizations architect and implement the data infrastructure that powers their analytics and AI systems. My journey started in 2009 as a Database Analyst, and I've evolved through roles spanning software engineering, data architecture, and engineering leadership across financial services, payments, conversational platforms, and gaming industries. Since 2022, I've also been sharing my knowledge as an MBA Lecturer at ESPM, teaching Data Engineering, AI & Cloud-Native Systems, with a focus on LLMs, prompt engineering, and real-world AI integration. My expertise bridges technical execution and business strategy. I translate requirements into scalable architectures without the usual miscommunication between teams.

Core technologies in my stack:

  • Python & Scala
  • Databricks
  • Apache Spark
  • Snowflake
  • AWS / GCP / Azure
  • LLM Integration
