What I'm looking for

I am seeking a mid-level data engineering role to build scalable GCP pipelines, optimize performance and cost, and collaborate with data scientists in a growth-oriented, collaborative team.

I am a GCP-certified Data Engineer with 4.8 years of combined IT support and data engineering experience, focused on building cloud-native ETL pipelines, real-time streaming solutions, and ML-ready datasets. I work extensively with BigQuery, Dataflow, Pub/Sub, Cloud Composer, Cloud Functions, and Python to automate workflows and prepare production-ready data for analytics and ML.

I have delivered cost-optimized pipelines and observability solutions that cut analyst query runtimes by 60%, reduced production debugging time by 40%, and accelerated ML feature preparation by 70% while enforcing schema governance and validation. I collaborate closely with data scientists and business stakeholders to translate requirements into reliable, maintainable data products that prioritize performance, cost-efficiency, and automation.
