I help companies turn scattered data into analytics systems that teams can actually rely on — from modern dashboards and reporting layers to scalable data infrastructure and operational analytics.

Over the past 5+ years, I’ve worked across SaaS, E-commerce, Finance, and Operations, helping companies build:

• self-service analytics
• executive reporting
• ETL pipelines
• anomaly detection systems
• data warehouses
• and scalable BI environments

My focus is not just visualization — it’s building analytics ecosystems that make data easier to trust, easier to maintain, and genuinely useful for decision-making.

❤️ The part I care about most?
Connecting clean infrastructure with actionable reporting.

A dashboard is only useful when the underlying data model, business logic, and pipelines are reliable.

What I usually help with:
• Data analytics & business intelligence
• Tableau, Power BI, Looker, Metabase, Microsoft Fabric
• Data warehouse design & analytics architecture
• ETL/ELT pipelines and reporting automation
• KPI systems and operational reporting
• Product, finance, and revenue analytics
• Self-service analytics environments
• Data quality validation and anomaly detection
• Dashboard redesigns and reporting optimization

Tools & Technologies:
• SQL, Python
• Snowflake, BigQuery, PostgreSQL
• dbt, Airflow, Fivetran
• Tableau, Power BI, Looker Studio
• APIs, cloud data platforms, automation workflows

A few things I’m proud of:
• Built analytics systems used daily by 5000+ users
• Worked with datasets from thousands to billions of rows
• Automated reporting workflows saving teams 20+ hours weekly
• Designed reporting layers and data platforms for fast-growing SaaS and E-commerce companies
• Led BI migrations and large reporting restructuring projects

I enjoy projects where analytics needs to scale properly — whether that means redesigning reporting architecture, cleaning up unreliable dashboards, improving data quality, or building a modern BI stack from scratch.

Good analytics should not just “look nice.”
It should help teams move faster, reduce operational chaos, and make decisions with confidence.
