I build developer tools and web systems that favor determinism over “smart” behavior.
Based in East Java, Indonesia. I care about predictable output, explicit APIs, and workflows that don’t fight the developer.
- Removing repetitive work from development workflows
- Designing abstractions that reduce cognitive load
- Writing TypeScript with clear intent and predictable behavior
- Treating DX as a system design problem

malas
Deterministic CLI generator for files, folders, and project structures.
No AI. No magic. Previewable output.

Markupless
High-abstraction JavaScript framework with implicit reactivity and no build step.
No JSX. No templates. Just logic.

- Deterministic systems age better than clever ones
- Abstractions should delete code, not add it
- Tools should help, not take control
