What I'm looking for

I’m looking to build reliable ETL/data pipelines and BI that turn messy data into fast, trustworthy decisions. I want roles focused on performance optimization, automation, and dashboards that directly drive action.

I’m a Data Analyst who engineers automated, high-throughput pipelines to unify data sources and accelerate reporting. As the sole data analyst, I partnered with IT to streamline lead-generation workflows by building reliable integrations across CRM and third-party data.

I migrated Pandas-based ETL scripts to a local PySpark setup to process 1M+ records without memory issues, improving pipeline stability and reducing batch runtime by 10–15 minutes. I also developed modular transformation scripts that improved data quality and reduced errors by ~15%.

I build BI-ready models and dashboards using tools like Looker Studio, Power BI, and dbt, and I enjoy pushing performance and automation further—containerizing an internal LLM-based Q&A system with Docker, AWS EC2, IAM, and S3 to speed up knowledge retrieval. From ELT pipelines in Snowflake/BigQuery to GCP-based crime analytics, I aim for fast, dependable data products that help people make better decisions.
