About

Engineer, builder, lifelong learner.

I'm Tô Gia Bảo, a Data Engineer at Timo Digital Bank by BVBank. I build cloud data pipelines, orchestration workflows, analytics systems and AI-assisted tools using Python, SQL, AWS, Airflow and dbt.

I care about explicit system boundaries, observable operations and designs that remain understandable as they grow. My current interests include lakehouse architecture, infrastructure as code and AI-native data tooling.

Building batch pipelines, lakehouse analytics and AI-assisted internal tools across the platform and operations stack.

  • Built batch pipelines syncing MariaDB into a landing–curated–analytics lakehouse with Amazon EMR and AWS Glue, masking PII before curated data and using dbt for analytics-ready models.
  • Built a FastMCP server powering conversational analytics in Slack, grounded in dbt docs, Lightdash dashboards and semantic-layer metadata for self-service discovery.
  • Automated MongoDB backup validation and general-ledger lookups with Python and Airflow, eliminating recurring manual effort.
  • Built GenBI dashboards and monitoring for Airflow, Athena and S3 with Lightdash and dbt, and migrated Timo Metrics from Loki and Grafana to SigNoz.
  • Delivered Tracking247 for the Customer team: a Streamlit app with Airflow pipelines syncing shipment status into MongoDB, centralising updates and cutting manual follow-up.
