About this Gig

Stop wrestling with messy data and broken pipelines. Lets build an infrastructure you can trust.

I specialize in designing and building production-ready analytics infrastructure, from automated ETL pipelines to highly optimized Data Warehouses. Whether you need to pull data from a messy API, set up event-driven microservices, or design a PostgreSQL database with strict Row-Level Security, I deliver clean, scalable, and documented solutions.

What I can do for you:

  • Custom ETL Pipelines: Automated data extraction, cleaning, and transformation using Python and PySpark.
  • Data Warehousing: Designing optimized Star Schemas, handling Slowly Changing Dimensions (SCD Type 2), and implementing Materialized Views.
  • Database Architecture: End-to-end PostgreSQL and Supabase setups.
  • API & Event Integration: Building robust connections via REST APIs or event-driven systems using Apache Kafka and Docker.
  • Business Intelligence: Preparing clean datasets ready for Power BI dashboards.

My Tech Stack: Python | PostgreSQL | Supabase | Apache Kafka | Docker | PySpark | Next.js
