Experienced Data Engineer Specializing in Scalable Data Solutions

Empowering businesses with innovative data pipelines, cloud architectures, and real-time streaming solutions. Leveraging expertise in Python, SQL, and GCP to deliver impactful, data-driven insights.

About Me: Turning Data Into Actionable Insights

My professional journey began in analytics, where I was deeply engaged in managing government website analytics, running reports, and identifying patterns to inform decision-making. As I delved into the underlying systems and code powering these insights, I discovered a passion for the technical challenges and creativity involved in building data solutions. This fascination drove me to expand my expertise into data engineering and full-stack development.

Over the years, I’ve had the privilege of contributing to diverse environments, including government contracts, non-profits, and established organizations. Today, as a Lead Data Engineer, I design and optimize scalable data architectures and workflows. My work spans the entire data lifecycle—gathering, cleaning, transforming, and processing data—to deliver actionable insights that empower businesses to make informed decisions.

In my free time, I channel my passion for coding into full-stack development projects. From concept to deployment, I create applications using technologies such as Python, TypeScript, React/NextJS (App Router), Redis, and Postgres. These projects allow me to explore the latest technologies and refine my ability to write maintainable, modular code. Currently, I am focused on a side project using NextJS, Prisma, and REST APIs to automate marketing data flows at scale.

Here are some of the technologies I work with regularly:

  • Python

  • SQL

  • BigQuery

  • Apache Airflow

  • Notebooks

  • Pandas

  • REST APIs

  • Redis

  • Docker

  • Postgres

  • Apache Kafka

  • Apache Flink

  • Data Modeling

  • Google Marketing Platform

  • TypeScript

  • ReactJS/NextJS (App Router)

  • Prisma

  • Git/GitLab/GitHub

  • JIRA
