About

A little about me

Flutter apps, FastAPI backends, ML models — I build software end to end.

I’m a Computer Science student from Medan, Indonesia. I write apps with Flutter and Dart, backends with FastAPI and Serverpod, and machine learning code with Python.

What I Do

Cross-platform Apps

Flutter & Dart for iOS, Android, web, and desktop from a single codebase.

Backend Systems

FastAPI and Serverpod services that are tested and easy to extend.

Machine Learning

Python, Pandas, and XGBoost models that ship — not just notebooks.

Current Focus

A quantitative research & backtesting platform.

Backtesting Engine Event-driven Architecture Strategy Research Portfolio Analytics Multi-Asset Support

The software I like to build stays simple to use — even when it’s doing something complicated underneath.
