01 · About

An engineering approach to business intelligence.

I'm Taufik, a Power BI Developer and BI Consultant with more than six years of experience turning complex business data into clear, decision-ready insight.

My background is in Information Technology (Information Systems), and I've delivered analytics work across the insurance, telecommunications and automotive industries.

My work centres on Power BI — Power Query for data preparation, star-schema data modelling and DAX for the KPIs that matter. I'm currently deepening my skills in Microsoft Fabric and modern data preparation, applying what I learn directly to the Power BI solutions I build.

04 · My Approach

A disciplined path from raw data to decisions.

Every engagement follows a disciplined, end-to-end Power BI development process — from the first requirements conversation to a deployed, maintained report.

01
Understand Business Requirements
Stakeholder interviews to define the business questions, KPIs and success criteria before any data work begins.
02
Data Exploration and Assessment
Profiling source systems to assess data quality, availability and structure before designing the solution.
03
Data Preparation with Power Query
Shaping and cleansing source data with Power Query — standardising, merging and consolidating tables before modelling.
04
Data Modelling
Designing star-schema semantic models with clear relationships, hierarchies and calculation logic.
05
DAX Development and KPI Design
Writing performant, maintainable DAX measures that encode the KPIs the business runs on.
06
Dashboard Development
Designing interactive, accessible dashboards that surface insight without overwhelming the user.
07
Performance Optimisation
Optimising queries, model size and visuals for fast, responsive reports at scale.
08
Deployment and Maintenance
Publishing, securing and supporting reports — with governance, documentation and iteration over time.
