QuickGold

Senior Data Engineer

Python SQL Power BI

Context

Operations ran on disconnected ERP systems with no unified view of the business. Reporting was manual, slow, and error-prone.

What I Built

Built ETL pipelines to consolidate ERP data into a single source of truth. Designed a data model for analytics and delivered Power BI dashboards for operations and finance. Automated key reporting workflows end to end.

Impact

Reporting time cut from days to hours. Teams moved from spreadsheets to live dashboards — faster decisions, less manual work.

Previous Experience

Data Engineer

Python SQL BI Tools

Context

Multiple companies with fragmented data sources, no reliable reporting layer, and high dependency on manual processes.

What I Built

Designed and maintained ETL pipelines across different industries. Integrated data from APIs, databases and flat files into centralized models. Built reporting layers consumed by operations and management teams.

Impact

Replaced manual reporting with automated pipelines. Consistent data across teams, less time on data prep, more time on decisions.

The Engineer Behind the Data

"Good data engineering is invisible — you only notice it when decisions get faster."

I’m a Data Engineer with 3+ years building pipelines, data models and dashboards in production environments. I’ve worked with ERP systems, ad platforms and operational data — the kind of data that’s messy, business-critical, and needs to actually work.

Beyond client work, I’m building data products — tools that solve specific problems I’ve seen repeatedly in the field. The goal is always the same: less manual work, faster decisions, and clear visibility into what’s actually happening in the business.
