About

Data & Analytics Specialist.

Hello! I’m Yogi Maulana, a Senior Data & Analytics Professional with over 8 years of experience building enterprise-grade data infrastructure, analytical models, and robust Business Intelligence platforms.

My journey began in Data Analytics, where I focused on uncovering insights to optimize marketing budgets and improve customer retention. However, I quickly realized that great analysis requires an even stronger data foundation. This passion drove my evolution into an Analytics Engineer—the architect who designs how data is ingested, transformed, and delivered.

I believe that data shouldn’t just sit fragmented in a warehouse; it should serve as a company’s strategic compass when backed by the right architecture.

I specialize in building production-grade data pipelines and scalable dimensional data models. Utilizing a modern tech stack centered around SQL, dbt, BigQuery, and Airflow, I help organizations turn fragmented operational data into a clean, tested, and fully documented single source of truth.

Throughout my career, I have focused on driving measurable efficiency and value:

  • Accelerating Data Delivery: Standardized data models using dbt, successfully reducing data delivery turnaround times from 1 week to just 1 day to enable rapid business decision-making.
  • Automation & Scalability: Designed data solutions that accelerated financial reconciliation for over 200,000 monthly records, reducing processing time from 2 weeks down to 3 days.
  • Data Governance & Quality: Consolidated fragmented, multi-source operational data and implemented strict quality testing that eliminated 12% of data inconsistencies for reliable reporting.
  • Mitigating Revenue Leakage: Engineered automated anomaly detection and alerting systems within data pipelines, successfully protecting business revenue from critical integration and billing failures.

  • Languages: SQL (Advanced), Python, PHP
  • Data Warehouse & Infrastructure: Google BigQuery, ClickHouse, PostgreSQL, Docker, Linux
  • Data Engineering & Modeling: dbt (Models, Tests, Macros, Docs), Apache Airflow, Git/GitHub, CI/CD, API Integration
  • Business Intelligence & Semantic Layers: Power BI, Tableau, Metabase

Whether you are an Engineering Manager looking to scale a high-performing data pipeline, or a Business Leader wanting to transition away from manual, error-prone spreadsheet reporting—I can help you build an analytics infrastructure you can trust.
