FOUNDATION
Mining Engineering, University of Tehran
A technical foundation in complex systems, quantitative work, and structured problem solving.
About
Engineering discipline, applied to business intelligence.
Power BI developer based in Tehran, working remotely with global clients—and expanding into Airflow, dbt, and Python dashboards to bridge BI and data engineering.
The path
A deliberate move into BI.
The route was not linear, and that matters. Engineering built the analytical base; freelance work built the habit of shipping for real clients.
THE SHIFT
Freelance BI work
Early client projects turned data analysis into practical reporting—work that had to be understood, trusted, and used.
BUILDING RANGE
Spark Intel Group & BI Story
Dashboard delivery expanded into remote collaboration and global client work across retail, supply chain, finance, and tech.
TEACHING
Data Analyst Mentor, Data In Motion
Three months mentoring analysts—reviewing their work, sharpening their questions, and explaining the reasoning behind every technique.
TODAY
Product Developer at BIBB
Building the Theme Generator, CF Icons tool, and reusable Power BI templates alongside independent consulting.
“I had the chance to work with Sajjad on a project, and he’s honestly one of the most professional people I’ve worked with. His strong design sense and deep DAX skills made everything easier to understand and use. He’s always easy to collaborate with, and I’d happily work with him again on any project.”
LinkedIn recommendation from a coworker
How I work
Business question first. Always.
Start with the business question
Not the visual. The decision defines everything that follows.
Design first, then model and build
The interface sets the requirements the data model has to meet.
One clear story per dashboard
A report that answers everything answers nothing well.
Document and explain
Teams should be able to use and extend the work without me.
