An independent data and analytics engineering practice

Idzharul Huda is the practice of Idzharul Huda, a data and analytics engineer in Jakarta, Indonesia. It builds data platforms end to end and rescues the ones already running: ingestion, warehouse modelling, orchestration, and the reports people open every day.

The work is done personally, from the first call to the handover. Engagements usually start from one platform problem, an assessment of something already running, or a delivery that has to land inside the tools a team already uses. The four services on the home page describe how they usually begin.

Alongside client work the practice ships its own products. RaschLab, a platform for Rasch model calibration and item analysis, is the first: in pilot since September 2026, built on an engine checked against Winsteps output for parity on identical input.
