I'm Izzulhaq Mahardika, a software engineer working across web applications, data pipelines, and the platform glue in between. This site documents my work the way I'd document a product: problem first, architecture second, trade-offs in writing.
Tip
Every project page follows the same shape — Problem, Architecture, Stack, Results, and What I'd do differently. If you only read one section, read the last one.
