I design and build data-driven software — from enterprise ERP systems to machine-learning forecasting apps — grounded in 5+ years of engineering experience and a formal background in mathematics and graph theory.

I'm a Software Engineer with a Bachelor of Science in Mathematics from Universitas Andalas. For over five years in software-house environments I've specialized in ERP development with the Odoo framework — leading module design, data migration, multi-database server management, and end-to-end implementations that streamline real business workflows.
My backend core is Python and PostgreSQL, complemented by modern web development with JavaScript, React, and FastAPI. On the data side, I build sales-forecasting and analytics applications, applying statistical models and machine learning to turn raw numbers into actionable business insight.
The mathematician in me never left: I've published research on rainbow connection numbers in graph theory, and I bring that same rigor — decompose, prove, optimize — to every engineering problem. Originally from Sungai Limau, West Sumatra; currently building things in Tangerang, Banten.
The tools I reach for daily — from backend cores and ERP internals to statistical modeling.
